Koss Pro4AAT Titanium Pro Headphones Review

First off, I would like to say that these are some of the best looking closed ear headphones anywhere near this price range. If you don’t have the want or money to buy a 0 pair of headphones then these are for you! First off I shall list some of the pluses for this product then followed by the negatives.

Pros:

- Lets face it, these are some beautiful headphones! They use the right materials in all the right places!
- I like closed ear headphones which block out background noise and these do the job very well.
- The mid-range and treble sound levels are really nice on these.
- You can’t scoff at the lifetime warranty! It’s one of the best things Koss is known for!
- The coiled headphone cord is a big plus! It makes owning a set of cord headphones quite nice.
- Oh, did I mention how good looking these headphones are?

Cons:

- My biggest complaint with these headphones would be that the bass sound level is somewhat soft. If you love to listen to your music with a ton of bass, then these aren’t the headphones for you.
- As with any closed ear headphones, they can get a little tight on your head after a while.
- Not really a con for myself, but everyone’s head varies in size so a set of closed ear headphones won’t be perfect for everyone.

With your own marine audio systems, you can transfer your car system to your boat. It is quite new in the market but a lot of stereo products have already been customized to be used on the boat.

In fact, there are car audio manufacturers that are specifically designing for marine audio systems.

You can design your own marine audio systems by following the same steps. Survey your boat. Check the areas where the audio products are placed and see whether the water can reach these.

The amplifiers are placed in the engine compartment near the rear of the boat or under the dashboard. The delicate parts should not be close to the water. The subwoofers can be placed under the seats.

The radio replaces the original radio. With your customized system, you can also adjust the midbass and midrange speakers as well as the twitters. Do this so that the system can fit under the dash or into the side panels.

It helps to take photographs of the locations you would put it in. At least you already have the dimensions with you. These facts can help you choose the products that will fit in the places that you selected.

You can lay the system out in your head or draw it out. Make a plan. Determine where you will put all the components.

For research, you can contact the manufacturers. By using their pattern of where to route the wires, you can set your system up in a coherent manner as well.

You can also contact them for retailer recommendations. By comparing the parts of the marine audio systems, you can canvass for the parts that you want and the parts that you need. Set your marine audio systems up that is your most ideal.

When choosing speakers, we suggest that you get the polypropylene. This is a rigid material that can resist moisture. You can have two 10 inch subwoofers for your speakers.

Remember to design the speakers that will be appropriate for infinite baffle mounting. You can also include four other speakers that are separate from the main ones.

Just make the two way speaker of your marine audio systems the midbass speaker and the midrange speaker. Don’t forget to include a tweeter.

After you’re done designing, take a step back and look at your masterpiece. Then take a step closer and listen in.

The Book: More Than The Gift – A Love Relationship

Author: Mr. Larry J. Robinson

Aventine Press – copyright 2009

ISBN: 1-59330-594-X

LC # 2009930804

Introduction

Larry Robinson is a man with an assignment from God. This assignment is to more fully equip the average parishioner with a better understanding of what it truly means to give our tithes and offerings. He has served in several positions within the church body which have given him a very clear perspective on the issue of tithing and the attitudes that surround this important part of our relationship with God. While checking out his website, I discovered a very passionate and truly inspired man who I feel God is using in a very powerful way. Larry Robinson has demonstrated with this book that he has a very firm grasp on the greater importance God places on our attitude vs. just the physical gift. Mr. Robinson with his wife Sharon and his four sons have served faithfully at four church bodies over the span of his walk with Jesus. God has used their personal journey to shape and define what he wants told to others. In my understanding, God gives important assignments like this to only faithful and devoted people who have a heart of love and grace. In reading this book and web site, this is what I perceived.

Summary

The book “More Than The Gift” is 125 pages long and takes its reader on a journey of what it’s like to open up are heart and mind and really give from Gods point of view. This book is basically divided into three sections. They are 1) God’s interests in our giving, 2) What are giving reveals, and 3) What are giving accomplishes. These three areas cover everything we need to understand about giving in general and into ministry. Larry Robinsons book shows how giving is really for and about us. He describes beautifully how God is primarily interested in our relationship with him and not just some legalistic mindless routine which I’m afraid many of the body of Christ fall into over the years.

Review

This writing is well thought out and deals frankly with all the issues of giving that many are struggling with today in the churches across the world. It is filled with family references and has some well placed stories about others who have experience lessons from God in the area of giving and attitude. The frankness is the strong point of this book because it is written narrowly focused with the average church attendee in mind. The author takes us step by step through the process of giving from having a pure motive to understanding how giving actually benefits us the giver multiplied times. He shows us that motive and attitude is everything with God. I personally responded with a favorable feeling after reading this book and it did convict me to read it completely through which by the way took about two hours.

Recommendation

“More Than The Gift” offers a clear and very easy read. I would recommend buying this book to all pastors and use it to teach the true meaning of giving to Sunday school classes and as a give away to church members year round. While many churches struggle with asking their members for tithes and offerings today, this book would easily help with the transition from parishioner ignorance to having a wanton desire for giving. It removes the stereo types that surround this very important aspect of our relationship with God. I thank the author for being obedient to his assignment, and his book “More Than The Gift”, will truly inspire and more importantly bring people a closer more fulfilling relationship with God.

Surrounded

The hype of 5.1 and huger surround seems more active than ever… except in sales.

Back in the early days of Dolby Digital and DTS I stood up for releasing music in multi-channel formats. I still do.

The thing is just that I do not uphold the “Dolby Digital” or “DTS” 5.1, or 6.1 or whatever approach, it makes little sense to me, speaking in commercial terms, because of the comfort sacrifices it forces you to, when listening to it. Remember you may leave the music playing in the room and listen from the kitchen.

So, I think most people just won’t go trough the trouble of buying a music “DVD” just by imagining sitting in the couch while it plays, exploring all the 5.1 surround activity. I speak for myself, having countless high-definition audio surround titles, I *only* listen to these in the former mentioned scenario, thus, rarely.

What do I think should be the way then?

Stereo still rules

No matter how much DVD players get lower in price, or compression algorithms get multichannel, the thing is that… The main thing is still the music, the thing you whistle too, tip the toes at with or get the goosebumps from.

Truth of the matter is that now matter how good people’s Home-Cinema systems get, as far as music use is concerned, they will probably just stuff in a quite common normal audio CD in there, or SDCards or whatever.

The immersive surround makes more sense watching a movie or playing a game, not quite so listening to music which, some even just “display” for the neighbors, leaving the room due to very high volume, or dance away from the speakers, and I do mean away – not good for feeling immersive effects the producer wanted his 5.1 music to give you, which means, for that, you should stand in the geometrical center of all 5 or 6, or even 7 (for now) speakers…

… Ah, and have I mentioned that in many cases the speakers are incorrectly placed?

Encoding

So, to me, the solution, as far as investing in music audio production, still lies with the stereo approach as root, and… to add some value, if need be, the surround. Although there are a lot of ways you can do this, I use two (please mind that for HighDefinition content I use MLP and WMA lossless):

- Windows Media Audio Multichannel encoder (or similars) – Dolby Prologic or similars

Sticking to the examples, Windows Media Audio allows you to encode several channels of audio but downmixes to stereo transparently if you are listening in stereo. Dolby Prologic, if version II, encodes a 5(.1) matrix into a stereo file, if IIx, goes up to 7.1, and although the listener may enjoy it in stereo (with the hyped iPod, for example, and headphones) he can also, if in the mood, stuff the source into the Hi-Fi, turning on the suitable ProLogic decoder and getting the full 5(.1) channels from the stereo file or more.

There’s some loss of quality doing phase encoding in a stereo file to get the extra surround channels, but, for the reasons stated above, some of which related to the kitchen/room scenario, that difference won’t make that much of a difference.

Please notice the “.1″ in all the stated cases, which is the sub-bass channel, is handled automatically, hence, removing bass from all channels, it’s not a dedicated channel in ProLogic, but may be with Windows Media Audio.

Speaking of 5 channels surround, the problem with Windows Media Surround Encoder (and similars) is that, since they encode the whole channels, the file size is around, lets say, for sake of argument, bigger than a simple stereo would be (prologic is encoded in stereo) – not good for bandwidth (specially in high-quality, high bitrate versions).

On the other hand, if you had a stereo encoded Prologic II file, the size would be the simple stereo normal size, hence, around a few times less if you count off compression tricks, with all the channels there. Good for bandwidth, best for high bit rate encoding with no worries for size, and you can listen in an iPod or at home with your pride and joy home-cinema system in full 5.1, having downloaded a simple, small, ingenious simple stereo file.

Thus means, ProLogic is also good to burn straight on to a normal stereo CD…

My vote

So, you may have guessed it by now, my vote goes for plain stereo with encoded ProLogic information and that is probably my future orientation, if I don’t stick with plain stereo – which would be option zero, the original vote, but I like to add value, and multi-channel does just that.

On the other hand, I uphold and defend HD multichannel (24bit/96khz) should be 5.1 in heart, engineered to be so with the highest of qualities, but only to be sold along side the standard material, for true appreciation – I’m not a supporter of compressed high-definition multichannel downloads, I want it all, linear, or, at most, 75% of it (WMA Q75 mode, similar to MiniDisc quality).

The future

I believe the future may very well render effortless many hours of sweat some insist on going through to have a good 5.1 mix (many sound really lousy). The thing is that DSP (digital signal processing) will have such a huge amount of processing power that it will take any audio signal and do whatever it wants with it.

So, from a crappy mono feed, you may end up with a glorious 12.2 surround artificial but realistic environment, and move trough it in real time, as with most games nowadays. So my motto is to focus on music, balance, production, emotion, and stereo, with optional spreading to a well mixed 5.1 (actually it’s the reverse, but who cares) for marketing and personal pleasure reasons for, under all this reasoning, monophonic would be enough.

If you own an older television, chances are you may have to use a few different tools in order to get clear, quality digital picture. Many televisions today have these ports and adapters attached, but other old models will need a little bit of an extra push. To change it up and make the picture better and brighter you will need an S-Video Composite adapter. You can do it all on your own without spending a penny as long as you have the right equipment at home!

Many older televisions have only composite video input that will not work with the usual DVD players and other new age electronics. Now, you can buy an adapter for a small amount of money, or you can easily turn your S-Video device and strip it down so that it will become an actual composite adapter so that anything you want to use will become compatible with your particular television.

The first thing that you need to do is take the S-Video connector and strip it down so that you are revealing 4 different wires. Each wire will have a different color, typically yellow, white, yellow and green. Strip it down enough so that you have some room to work with when you start working with the composite. Pins 1 and 2 (known as Y ground and C ground) in the S-Video cable will need to be connected to the composite ground. This will be located in the RCA connector that you have on your television.

From there you will need to connect the remaining wires; short pin 3 belongs in the hot pin of the connector. You should then just have to use a 470f capacitor between that hot pin and the last short pin on the S-Video connector. From there you should be able to see a picture and the device that you are looking to use should be able to connect and send the images to your television. However, keep in mind that this is simply a quick fix so that you can buy some time before you buy a brand new television.

Those who have accomplished this do-it-yourself task have had no trouble using the S-Video Composite adapter properly. If you have different colored wires than the ones mentioned above, you may want to play around with the short pins in order to see which ones should go together. This process should not take more than about 20 minutes, which means that you can easily have your TV up and running in no time!

As time presses on, there will no longer be a need for the composite port. Many people are upgrading and using plasma and LCD televisions that have an overall higher level of quality, picture and sound. The S-Video Composite adapter is a great way to temporarily solve an issue and allow you to sit down and watch your favorite DVD’s and play all of your favorite games, without having to spend a single penny!

There is nothing like finding the best stereo headphones available on the market, but sometimes, those phones labeled “best” are not always the best ones for you. Often times, lists are created based on the popularity of a device, the brand name, and overall quality. And sometimes a reviewer may mention a pair that is perfect “except for the fact that they make your ears sweat.” However, in owning yours for three years, you’ve not released one drop of sweat. This is why it is important to find what is best for you, despite all of the reviews. Locating this perfect choice will require research, however, meaning you can’t just find a pair that look nice online then order them because there is a good chance you will be disappointed. Instead, you need to look around, test them out yourself, and make an educated choice, because if you are shopping like the wise person I know you are, you will want to keep them for more than a year or two.

Do a “Stereophile” Check for Reviews and Recommendations?

Stereophile is one of the most popular print and online stereo magazines available and it provides a “Recommended Components List” every April and October that gives great suggestions for top devices that are best in price and quality. Of course this is not necessarily where you’ll find the best stereo headphones for you, but it is a great place to start. You’ll be able to get a good idea of what it takes to make a great set, plus you’ll get other ideas for other great stereo components – that is, if you don’t already have them.

Start Your Internet Search

I am a big fan of the Internet – within reason, mind you. I say this because, just as there is a lot of great information available, there is also a lot of false information. Many people make up information for ulterior motives, so while you can trust some of what is put out there, you cannot trust it all. One thing I do to check the reliability of a source is to check other sources and see if the information is similar – but not a carbon copy. It is easy to get out there and copy exactly what someone else has written and you will found a lot of that out there. So check source after source, making your research comprehensive. Also, look at what others say about the particular pairs that appeal to you. Most people give honest reviews as a way to warn others and help them avoid wasting their money, so take their advice seriously that is unless the reviewer seems to be a “brand basher.” Finally, check those that so far seem to be the best stereo headphones against your Stereophile reviews and recommendations to see which ones appear to match in quality. But remember, you might find ones that seem to the winning pair – that doesn’t mean they are the best stereo headphones for you, so don’t let the research stop here!

Choose Between Circumaural, Supraural, and Intraural Stereo Headphones

The terms circumaural, supraural and intraural are fancy words with simple meanings. Circumaural headphones surround the ears and are typically known as closed headphones because of their ability to shut out most noise. They are very commonly used in musical studio sessions where there is the potential for outside noises and distractions. They can also be used as headphones in the home for those who either love to feel completely surrounded by their musical selections, want to shut out people and noises in and around the home, or both. While they are a great choice for many people, they may not be the best stereo headphones for you, so keep searching!

Supraural headphones usually sit on the frame of the ear and have soft ear pads. They normally don’t block out all, or even most, sound but can, often times, still give a great sound quality. Usually they are little less expensive than the circumaural headphones, which may be ideal for those who don’t care to block out the world. However, depending on the padding used to cover the speakers, your ears could become irritated, so it is a good idea to find the ones that work well for you.

Intraural headphones, also known as earbuds because they fit inside the ear canal, are more commonly found for IPods and MP3 players, or any other portable device. However, if you’re particularly fond of this style then they may be the best stereo headphones for you. You can find high quality in all versions, so the don’t feel that you have to hold back on your decision because of the style.

Determine What Works with Your Current Stereo Components

If you already have your choice stereo components at home, then you will want to make sure that you choose the best stereo headphones for those components. While many components naturally work well with each other, some don’t. And just because you buy components of the same brand does not necessarily mean that they will collectively produce the best sound. So it is important to incorporate into your investigation a comprehensive check for the best component collaborations.

Test Headphones in Person

Once you’ve done all of the research you can and have narrowed down your search to a few that you really think you’re interested in, it’s time to get out there and find those perfect headphones. You will want to visit the stores you’ve found that sell the ones you’re looking for then ask the sales associates to let you test them out. They will normally have some CDs they can use to test them, and if you can, have them plug the headphones into the device you own or plan to buy. Once you have narrowed down your search, you’re set to make your dream headphone experience a reality!

Finding the best stereo headphones for you doesn’t have to be rocket science. Once you do your research and follow your instincts you’ll be on the right path to finding what you’re looking for. In the meantime, it doesn’t hurt to sit and daydream about the best stereo headphones in the world. Before you know you it, the perfect ones will be sitting around, on, or in your ears, blessing you with the musical experience of a lifetime.

The optimum TV screen size is directly related to the available viewing distance – but there are other factors as well that need to be taken into consideration.

Viewing Distance: Is it just a matter of personal preference?

Sit too close to your big screen TV and you will be able to see the image build-up structure – scanning lines or pixels forming the image – thus distracting your attention and spoiling your home theater experience. Yet, sit too far away, and the impact will be lost.

There are differing opinions on the best way to determine the optimum TV viewing distance for a specific screen size. Just go to the movie theater and you will soon realize that it is all a question of personal preference – some would sit at the very back. Others would go straight to the front row, as they prefer the bigger picture and a wider angle of view, while some would simply choose their seat randomly somewhere in between these two extremes.

The truth is that there are no scientific rules her. This does not mean that there aren’t any guidelines that you should follow when planning a big screen purchase or a would-be home theater room.

SMPTE Recommendations and the THX Certification standards:

The Society of Motion Pictures and Television Engineers (SMPTE) recommends that the screen size for home theater use should occupy a 30 degrees field of view – in the horizontal plan – for the audience. Alternatively, the ideal TV viewing distance should be such that the screen width occupies an angle of 30 degrees from the viewing position.

This 30-degrees viewing angle seems to have been accepted by many as the standard in home theater and motion picture viewing.

This SMPTE guideline is also in line with the THX certification standards in that these recommend that the back row of seats should have at least a 26 degrees viewing angle and while recommending an optimum viewing angle of 36 degrees.

It is believed that within these viewing angle limits, the viewer will get better immersed into the action movie itself.

Vision System limitations:

There is also the issue of TV viewing distance based on visual acuity. This does not represent the optimum viewing distance – rather, this relates to the maximum viewing distance beyond which some picture detail will be lost.

Technically speaking, visual acuity is a measure of the eye spatial resolving power and indicates the angular size of the smallest detail that a person visual system can resolve. A person with 20/20 (or 6/6 when expressed in meters) normal vision can resolve a spatial pattern separated by a visual angle of one minute of arc angle i.e. 1/60th of a degree, at the eye when viewed at 20 feet away. Expressed differently, a person with normal 20/20 vision is capable of identifying an object with a height of 1.76mm at 20 feet way.

In terms of TV viewing distances, these represent the point beyond which some of the picture detail will no longer be resolved by the viewer vision system.

So How Does All This Translate In Practical Terms?

A few rules-of-thumb can help put in practice the guidelines detailed above. These rules for viewing distance refer to the screen width rather than the screen diagonal and therefore apply to both 4:3 and 16:9 display formats.

A general rule for the TV viewing distance based on the SMPTE and visual acuity guidelines, is that the nearest TV viewing distance between you and your big screen TV should be limited to approximately twice the screen width (more precise 1.87 x screen width for a subtended angle of 30 degrees), while the furthest distance being no more than five times the width of your screen.

This rule of thumb should give you a fairly good approximation for your TV viewing distance. It does not necessarily represent the ideal home theater viewing distance but rather the limits within which your TV viewing distance should theoretically be out of the trouble zone.

In other words, move closer than twice the screen width size, and the picture scanning lines, pixels and any other video artifacts will become too visibly intrusive – leading to distractions that will spoil your movie watching experience. Move further away than 5 times the screen width and your vision system will no longer be able to resolve all the picture detail.

But…

It is also important to realize that these maximum and minimum viewing distances should be seen in the light of the video signal definition.

A fully resolved high definition TV (1080i, 1920×1080) supports a closer viewing distance than standard analog TV. Thus while twice the screen width would be the ideal TV viewing distance for a HDTV display, it would be a bit too close for standard TV; in the later case, a three times the screen width would be a better option.

Similarly, the five times the screen width as the maximum view distance, while more than adequate for a standard analog TV picture, is a bit too far away for a person to see the fine detail supported by a HDTV picture – a three to four times the screen width represents a more practical limit for the maximum viewing distance in the case of HDTV.

These rules-of-thumb work best with big screen TV sizes in the range 42-inches and over.

When it comes to the use of regular-size standard definition analog TVs in the home theater, i.e. up to 36″ / 40″ diagonal, the optimum viewing distance range is between 8 feet and 12 feet. TV sets smaller than 36-inches aren’t big enough to qualify for Home Theater use; their smaller screen size will not provide the desired impact on the viewer.

Vertical Angle of View & Screen Height:

For optimum viewing, the eyes of the viewer should be level with the center of the screen.

Maximum vertical angle of view: In those home theater set-ups where this is not possible, the SMPTE guidelines suggest that the maximum vertical angle measured at the seated eye height from the front row center seat to the top most part of the projected image should not exceed 35 degrees.

This does not represent the optimum viewing angle but rather the limit beyond which the viewer will be subject to an increased neck strain.

This maximum vertical angle limit is always measured from the front row as this represent the extreme angle of view.

Minimum angle of vision: While there do not appear to be any specific SMPTE or THX guidelines in this respect, yet studies have shown that if the screen size occupies less than 15 degrees of the viewer’s vertical field of view, than that image appears small.

Practical Considerations:

In a typical home theater set-up, you do not need to really worry about neither the maximum vertical angle of view, nor about the minimum vertical angle of vision for an effective movie theater experience.

If one were to adhere to the recommended TV viewing distance of twice the screen width (as further detailed above based on the SMPTE guideline of 30 degrees horizontal field of vision), you would automatically be complying with the minimum angle of vision. The reason being that there is a fixed relation between screen height and width in accordance to your home theater screen aspect ratio of either 16:9 or 4:3.

Further more, in a typical home theater setup, it would be very difficult to exceed the maximum vertical angle of view beyond which you will be subject to an increased neck strain.

Taking into account that most home theater rooms are approximately 10 feet (3m) high, the resultant vertical viewing angle is normal well within the maximum of 35 degrees detailed in the SMPTE guidelines – all you have to do is just remain within the twice the screen width guideline for your viewing distance.
