I was not going to post this review until next week, but changed my mind. As with all things in life, this is only an impression from one mans point of view, with everyone else ears being different. This is my first official review here at Head-fi; it may not be my last nor the best review ever published. All depending on how much of my wallet I want to hold on to. (Currently have a built-in mouse trap attached) LOL
These Koss are my reference phones which I judge all other headphones. The Koss has excellent mid-range, true accurate bass like an Acoustic suspension speaker, and the treble presentation is very nice, crisp, and not bright or laid back/recessed. The Pro4AA T is the only phone to date that I can close my eyes listen and relax and find myself waking up two hours later, because they are so neutral and natural sounding. Making me go, “Oops they did it again”.
My statements in this post: http://www6.head-fi.org/forums/showthread.php?t=178230
Two statements posted for convenience on my thoughts of the Koss and why I am trying the K 701’s.
[size=xx-small]Post 1:
These are the best set of closed cans I have used to date sonically. If you can deal with the weight and the clamping force (about as much as the Sennheiser HD 600) on the head until they loosen up or stretch, you will love them. The weight of the cans are not an issue for me. As for the rubber ear cushions, they can get hot, but they are easy to wipe with a soft cloth if you sweat a little.
I faintly remember the sound of the older Koss Pro4AA, but the Titaniums sound better, with solid accurate bass, nice mids, and excellent high frequency. Instruments especially drums sound like drums, flutes like flutes (David Maracle [Spirit Flutes or Speaking Winds], guitars like guitars (Michael Angelo Batio [angelo.com]), and female vocals are awesome (Pink Martini, Anita Baker etc.)
As you can see, I love my Koss Pro4AA Titaniums, but they isolate so well that I can't hear my wife nor my teenage daughter when they are speaking, and when they are away from home I can't hear the phone when ringing at max volume. About the only thing I can hear well, but sort of faint is my medium size dog (Cocker Spaniel size) bark.
To no longer upset my wife because I can't hear her, I just ordered the K 701's and have a 2-4 week wait before I get them from HeadRoom. So I am hoping these open cans will give me sound similar/equal to/or better than the Koss. From the impressions of everyone on these boards they should. The open cans I have sound inferior (like toys) to my Koss.
Allow 140-175 hours of burn-in. While breaking them in I periodically listened and you can hear the sound change (open up).
25 hours-became more closed
75 hours-became a little bright
100 hours-began to come in their own
140 hours-opened up more
175 hours-sound changed, became more spacious, thought something happened to my equipment, but then understood they finally exhibited air, and have been happy ever since.
Hope this helps.

Sorry rodbac, I don’t post much on message boards, and this thread got buried very quickly. Find it more fun and interesting to read what others say, see the arguments and making up on these boards like a marriage. (ha ha ha)
I have auditioned several closed cans, nothing in the upper echelon though. Each time I continue to use my Koss as they sound better to my ears. Maybe because they are so smooth, full, and accurate sounding to me. They have rich mids, tight bass, smooth treble, not laid back and not forward.
Maybe this could be attributed to the titanium drivers. I don’t know. They remind me of a very tight, accurate, three way acoustic suspension speaker. (Former speaker guy here) The rubber surrounds I think add to the suspension analogy, by adding that suction cup tight seal.
Part of the reason I need better open cans is so I can hear my family speak as noted above. Plus I want the smooth sound similar to the Koss Pro4AA Titanium (acoustic suspension sound). With such good compliments of the K 701, I thought I would give them a shot. Plus my wife doesn’t mind right now since I can hear her when need be. ; )
I have open cans, Sennheiser HD497, RadioShack version of the Koss UR40, and Koss KSC-75 but come back to my Koss Pro4AA Titanium’s. Have also heard the HD600, HD595, but still like my Koss. Maybe I need to hear the upper echelon, but will not spend the money on them. Better to spend money on my son in college, and daughter after graduating high school next year, her college, and the new home I will be in a month from now.
If any of you are in the Dallas, TX area and have some higher end closed cans for me to hear, shoot me a PM.
P.S. If you ever want to block out the wife or girlfriend (he he he) these work very well.[/size]

Note: All of the above Classical music was performed by the London Symphony Orchestra and other artists.
Break-in:
K 701 – 168 hours (I have notice no significant changes since about 108 hours other than the soundstage opening up a little more)
Pro4AA T – about 1104 hours
Some may think the Koss Pro4AA T sounds veiled. If you think the Koss sounds veiled, then the K 701 is more veiled, which would make the HD 600/650 series sound like they are covered in quilts. However everyone hears things differently.
Sound of both cans
Neutral:
K 701 – A very neutral phone. I did not notice a hump in the bass, mid-range, or in the treble to my ears.
Pro4AA T – Neutral. I would have to say that the Pro4AA T’s are the most neutral phone I have heard. I have not heard any of the upper echelon, like the R10’s, Orpheus etc. They don’t display a bass hump, mid hump, nor are they considered bright in the treble. They would not be considered too mellow, display a veiled sound, or laid back sounds like most describe the Sennheiser’s. I know for sure that the Koss have a very flat sound, and are Studio type phone with the sweetest of sweetest mid-range.
Explanation of Neutral: Both phones play what the source and AMP are feeding them without being altered or altering the sound. What you hear is what you get. If music is recorded dry, it is heard or sounds dry, if music mastered fun, you get fun sound etc.
Natural: This is where these two phones begin to separate.
K 701 – The K 701 has all of the right sounds and does things right per say. It just does not have the weight in the instruments especially the drums. Left to right separation is nice and sound right. Plenty of Head-fi folk mention drums on most headphones just don’t sound like drums. That is where my Koss comes in. They sound thinner than my Koss.
Pro4AA T – This phone brings out the best in instruments with nice left to right separation. Drums sound like drums with weight/sustenance/texture. All aspects of the drums sound like drums (snares, all cymbals, kick/bass drum sounds like a drum). Chimes sound like chimes, bells sound like bells, , piano has weight like a piano should and sustains the sound as a piano should (holds the note).
I guess the best way to describe it is to say, you hear a live instrument in person and feel it. The Koss has that same sound but not the feeling/vibration you have in person, but it makes you imagine it and melt.
Bass:
K 701 – Bass extends very deep and is pretty accurate. Now as some have said they think it lacks bass, this is not true. I would however say that it lacks for better words, weight/impact/authority type sound some are looking for, but the bass is all there for me even at low volumes.
Pro4AA T – Bass extends very deep and sounds accurate like an Acoustic suspension speaker. It has weight/substance/impact/authority. It does not give you too much or too little bass, but as much bass as the song provides in its recording.
Mid-range:
K 701 – Has a nice mid-range but still not as sweet as the Koss. This phone only lacks a little again in the weight and texture of all instruments, as well as the sweetness of texture of what is the human voice in both male and female, but just a little.
Pro4AA T – Koss seems to bring out more of the weight and texture of all instruments, as well as the sweetness of texture of what is the human voice both male and female.
Treble:
K 701 – Liquid clear and clean with no notice of sibilance or peaks in brightness in my equipment after break-in.
Note: The K 701 sound was worse out of the box than my Koss were out of the box. One thing I can say is that there was something in the treble at first I did not like before at least 10 hours of break-in with the 701’s. It was something in the treble that actually caused ear pain. Like some sharp weird sound. I love them now.
Pro4AA T – Same as above.
Movies/Games:
Both cans are great for movies and games.
Conclusion:
The Koss Pro4AA T’s are still my reference phone by which I judge every other phone. They have sound which is more than their price suggests, are the top dynamic phone for Koss minus the Electrostatic phone (they were, see links at the bottom), and just does everything right to my ears. They are heavier than most phones in production, can have a clamping force on the head (they will loosen up), and most would not like the rubber ear cushions (can get hot, but are easy to clean with soft cloth vs. removing cushions and washing). The moral of the story here, is don’t judge a phone by their price point.
The AKG K 701 is an excellent reference headphone and complements my Koss well. I would not hesitate to mention this phone to anyone as a great neutral/natural sounding reference phone. However, this phone does not have the weight feeling of instruments as the Koss does. I will be keeping this phone for the reasons I needed to get an open good sounding phone in the first place. Other than not being able to hear my family because the Koss isolate so well, I did not want to sacrifice much in the way of sound that the Koss give me.
Each phone will reveal flaws in music recordings, even if the flaw is on CD itself. For those of you, who are interested in how they sound with Rock, well they both sound good with it, with the Koss getting the nod due to the weight and realistic sound of the instruments.
Many will read into this review thinking “What”? Is this guy for real? In the end as in the beginning of this review, “As with all things in life, this is only an impression from one mans point of view, with everyone else ears being different.”
P.S. PeeeMeS, I think the Koss can handle your bass but still will not sound like a car sub-woofer. Sound will have harder hitting bass, but with accuracy. I leave everything I hear flat.
As of this writing Koss has introduced two new phones as possibly their top dynamics, but jury is still out on them.
