Pros The sound. So pure and natural.
Cons I have had mine for about 20 year. Have replaced the earcuffs twice. Only con found.
Summary If you want the best try these. Nothing I have ever tried comes close. I have found many people with these. My wife had them before we even met, the same with my best friend.
Pros Studio Standard Sound Quality!
Cons Some people think the fit is awkward. I say: Not all heads are made the same.
Summary EXCELLENT *****
Pros Accurate overall tonal balance
Fairly comfortable for full size headphones
Cons At this price none.
Summary I bought my first Sony MDR V-6 sometime back in the early 80's. When the vinyl covering the earphones started to shed, I went shopping for another pair not necessarily expecting to purchase another MDR V-6 given how much time had passed. However, I was able to compare different phones at B & H and I found that I preferred the overall comfort and sound of the V-6 to any available comparison phones (including Grados and Sennheisers) that in some cases cost almost twice as much.
While the top models of Sennheisers did have a more finely detailed sound and accurate tonal balance than the V-6, they were going for $350 and up.
Now that I've had the new V-6 at home for awhile, I continue to be really impressed by their sound quality. One quibble is that the bass seems to be slightly overemphasized, but not nearly enough to mask other frequencies. My receiver has separate tone controls for headphones and I turned the bass down one notch.
I later purchased Pearstone foam wraps for the V-6 to replace the original vinyl which I then used to put on my original V-6. I found that the Pearstone made the phones a little more comfortable and also, I think, improved the sound by making it a little more 3-dimensional. There is a logical explanation for this - the foam on the Pearstone lets the sound from the drivers pass through to your ears while the vinyl blocks the sound. Therefore, the larger surface area from which you receive sound with the foam wrap on could account for the improved dimensionality.
Pros Bass. High treble. Comfortable. Relatively inexpensive.
Cons There is really nothing I can think of. Other than maybe the size for some.
Summary These headphones are almost indescribable with words. The highs all the way down to the lows are AMAZING! They are also very comfortable. You will not beat these headphones for the price. I mean honestly these headphones have been out for a VERY long time, and the fact that Sony is still making these headphones is ASTOUNDING! Listen to them and you'll never want to go back. I guarantee it unless you don't have an appreciation for music.
Pros Plays all types of music consistently, from R&B to Rock, to classical and ambient, through a full range, all notes are clear and crisp, the lows are awesome without overbearing. It even makes the ipod sound good.
Cons I wish the cord would detach(like the Bose), yes they are "studio" cans, but they sound so good i want to take them everywhere. And i wish i heard about these a long time ago. I still give them a 5 star because it's the sound im most concerned with.
Summary I have not tried all the headphones out there, but i do have a diverse taste in music, and i also make my own music, mostly ambient/ambient rock, and soundtrack, that being said, i believe i can distinguish what and/or how most sounds and/or music are intended to sound.
I tried my friends V6's, i was actually blown away. I then compared the V6's to Dr. Dre's 'Beats' headphones, the sound was right there with the 'Beats'.
The bottom line is that you can get the V6's for approx. $60, or $300+ for the 'Beats', i'm gonna say that so far(to me), the V6's are the best over the ear headphones you can buy for the money...easily.
