A bit about my collection Beyerdynamic DT880 250ohm AKG Q701 Sony MDR-V600 Sennheiser HD201 Sennheiser HD205 Sennheiser HD419 Grado SR60i The V6 used to be a standard in the recording and video/music production worlds and Sony decided to cash in on this by discontinuing the V6 and rebranding it as the 'Professional MDR 7506". They introduced the MDR-V600 as the consumer replacement to the V6. The only problem was that they didn't sound anywhere as good, had an all plastic construction, were bulkier, had strangly shaped earpads that were impossible to find replacements for, and were generally a much hated and inferior replacement. Sony took so much flack for this move in fact that they brought back the MDR-V6 from retirement just to shut everyone up. I can confirm after having listened to both that the V6 and V600 are a night and day difference. The V6 hits you immediately with it's build quality. These are small for on ear headphones with a compact but sturdy construction, a metal headband, and a somewhat dated style that comes out as 'classic'. They are the finest closed back headphones I own and that says something..... They are a little bass heavy but not in a heavy handed way and it in no way shadows the mids or highs. They do not color the sound much at all and should be excellent for mix down and mastering work as well as monitoring of live field recording. They drop off quickly above 10,000hz, far more than say the DT880 but in presentation it just doesn't sound like you're missing highs. They sound crisp, detailed, and musical. Because of their slim proportions and sturdy quality, and aided by their efficiency and ability to drive loudly from just about any source, these are perfect portable closed backs. I could drive them to uncomfortable levels with an Iphone and the coiled cable does not get in the way for portable use although it's a little on the heavy side. I prefer the metal headphone connector on these to the plastic ones on the 7506, and it looks better. The lack of gold plating has no effect on sound since plugging and unplugging ensures any oxide buildup is quickly worn back off. These headphones are a lot of fun to use and are very musical. They would work well for hard rock but sound good with any source material. Tracks I used to audition them include the Dave Brubeck Quartet, Nina Simone, Handel, Grieg, Skrillex, Arcade Fire, Angus and Julia Stone, Arch Enemy, they presented well with just about any genre of music. For the purchase price of $70 these are a better deal than the Grado SR-60i. They are much closer in quality to the large open back headphones in my collection than to the other consumer cans like the Sennheisers. I am incredibly happy with these and with a little EQ work they go from good to great. I performed some pink noise and sine signal sweeps and do not detect any major resonances other than HRTF's you get with any on ear headphones. They did drop off quite a bit above 10,000hz but extended at a lower level up to 16,000. You aren't going to dissect music with these but you will be able to mix and master with confidence the sound you create will sound good on any system you play it on. I would buy these again even if they were $120. Pros: Excellent build quality Compact design and light weight Excellent sound that is transparent and detailed, playful and punchy without sounding veiled. The style is retro in a pleasing way. Nobody is going to hear what you're listening too. Excellent isolation Excellent noise reduction from outside sounds. An excellent value Cons: They roll off quickly above 10khz The included headphone bag is a stiffer kind of plastic than the V600's and seems cheap. They are over ear but on the small side. It felt more like on ear and they do make my ears sweat after a few hours I wholeheartedly recommend these to anyone wanting headphones that don't need any EQ at all to sound good, whether you use them at home, or with portables, for music listening, or music production, these deserve a spot in any collection.
