4.5 Excellent reproduction but for MP3s, no amplification NethLyn | 23/01/2011 | See all NethLyn's reviews (18) This is the third pair of 201s I've bought since they were released. They're still very comfortable though might need wiping in summer depending how sweaty you are, the cable's still just about 3m when stretched out and measured and I keep them at home. When using them on any device with a powered headphone stage like hi fi separate players and PC speakers, they will do a great job of reproducing the source sound. Hook them up to an amp and turn off "Source Direct" or any other bypass button and that's when you could force them to distort if too loud, but by the time you did so, you'd damage your hearing!The catch is that for MP3 playback, faithful reproduction without the extra bass of the HD202s, can make this particular format sound thin and reedy, though WMA, M4A/iTunes and other formats seem better able to preserve bass when encoding from CD and WAV, aren't as badly affected - but it's something to take note of. The upside is, this will send you back to playing your source CDs for home use, and you can pick up some other set like the HD218s or the PX range for your walkman/iPod.For the GBP 14 price, this is the only issue to note and lots of people have snapped it up for their iPods as you don't need to kill your ears with bass all the time on the move - but they are more plasticky and bulkier than specialist ranges. If you're a rip-once kind of person then keep the MP3s at 320k and if making a WAV first, use software to push its volume to as high as possible before ripping, and the thin sound on ripped files won't be so bad - but if you must have relatively loud sound all the time on every single format, seek out the HD202s or PX200s/HD218 or their equivalents.
