Pros: Amazing sound, great price, extremely comfortable, very affordable.
Cons: Broke with minimal use (5-10 hours a week tops) after about 3 months, sound only comes out of the left speaker. They weren't dropped or stepped on or damaged in any way, it just stopped working out of nowhere. A little disappointing because I bought these headphones pretty much because of all the reviews saying how good quality and long lasting they are.
Summary: This used to be four star for me, but the earpads and somewhat the noise (which although don't hear that much anymore... still..) mess it up. The earpads are comfy, until they tear and the sides of your ear are touching itchy foam. One of mine teared a month ago and I'm asking it for Christmas tomorrow (6 dollars, but like 6 dollar shipping too), and today or yesterday my OTHER one got a small tear to (about half the size). Another 12 dollars.
Pros: The sound quality is pretty good, and the cord is long (if you like it that way)
Cons: On mine, there is sometimes a very quiet low pitch noise. Also, the cord is easily tangled. Forget lasting earpads, because these ones rip EASILY (at least for me) on the inside of the sides. Also, when you turn your head, it can be a little creaky
Excerpt: To be fair, I have only limited experience with this type of headphone. The sound quality, noise blocker and headphone manipulation are excellent. I was also expecting unquestionable comfort but it is uncomfortable to sit through an entire movie. I need to remove these headphones every 30 minutes or so because it begins to feel like my ears are lossing circulation and get in pain. I fear that if I was a ConeHead, I'd have to remove them every 5 minutes or so.
Summary: 3 eggs for Sony on this product. I have purchased many Sony headphones in the past and this is the first that I cannot tolerate for very long. I am happy with the sound quality but the cushioning needs more work...
Pros: Excellent sound reproduction NewEgg shipping... so fast, it's practically there the next day!
Cons: They hurt your ears after only a few minutes. My ears hurt so badly that I couldn't touch them after 30 minutes of use. The pads aren't flexible enough or large enough for normal ear sizes nor does this product have a break in period. I have used them for several days. After each use, my ears are tender and sore.
Summary: This is the first non-5 egg review for these headphones, and i was very hesitant to post this. I don't know if they need more time to break in, or if my last pair of 10+ year old plantronics were just so comfy my ears got spoiled... but if they it doesn't get better i'll have no choice but to either exchange them, or try to resell them and get a different pair. Kind of regretting not getting the sennheisers that were on sale here for 30% off.
Pros: These things sound great! The cord is very well done, definately looks and feels of high quality. The plugs are also very high quality and comes with the larger plug adapter. Again, they sound perfect, especially at this price point, very big bang for the buck.
Cons: My ears hurt extremely bad after wearing these things for even short periods of time. I played some CoD and SC2 last night for about an hour total just to test drive the sounds and my ears hurt so bad.. i couldn't even touch them. The next morning they still hurt.
Summary: Great bass output unamped. IMHO the bass output is this can's sweetspot. The sub-bass tends to roll off below ~35Hz, but the sheer impact from 35-100Hz makes up for it a lot. Midbass clarity is also very good in the 100-500Hz range. Bass guitar has good resolution over kick drum tripplets. Midrange frequencies can be overbearing. It has some nasty resonances from 3000-7000Hz. Unfortunately thats right at eardrum resonance.
Summary: The V6/7506 are quite overrated by many members. The treble is harsh, and grainy, and lacking extension. The bass is boomy, uncontrolled, and lacks any amount of articulateness. The midrange is terrible. My rating of 4/10 for the midrange of these phones is quite generous. The only thing worse is street styles. If you do not need sealed headphones do yourself a favour, and look for Koss PortaPros, or KSC55.
