Pros: Good sound at a low price
Cons: very short audio cable if you're looking to DJ
I bought these after popping into our local PC world and testing out all the headphones they had there. I was actually on a budget at the time and wanted to get as crystal clear sound as I could (none of that hyped up bass and brand nonsense) for a low price (£34). These were actually very well balanced, the bass was not at all over powering and let the highs (whilst sounding mildly thrashy) and mids poke through well. I no longer own these, as I hit a drawback with them - the audio cable is roughly a metre long. Whilst this might be acceptable for normal use I need these for DJing and you have to stay in close quarters to the console when you are limited to 1metre - no good for sifting through vinyl. I also noted the cable, which whilst looking very cool with its flatness also felt quite flimsy. In the end, my youngest son managed to tear the jack out of the mixer, and in doing so broken the nib of it. PC world were kind enough to give me a replacement which I put straight on Ebay.
I have been DJing using my ATH-M50s, and honestly they are fantastic, I would continue DJing with them in a heartbeat if they didn't have a dodgy jack, and were a little more comfy...and perhaps a bit more fasionable.
Anyway, I would recommend these to someone who just wants to listen to music in good quality, look good, and not burn a massive hole in your pocket. For DJing, not so much. It's also worth noting that the headphones a few marks up from this MDRV55's I think, not only appear Identical - but they also have the same short length of cable.
