Excerpt: Just bought these today in-store because my Cardo S-2 Bluetooth headphones broke last week and I wanted something with better sound quality. The salesman pointed me to the first generation version of these to sample the sound and then told me "Imagine that richness, plus great bass response.
Summary: I purchased these headphones just over 2 years ago from Amazon UK. The sound of the headphones is brilliant and the option to fold them up is great too. But In these 2 years I had to claim Sennheiser's warranty 3 times as one of the speakers stopped working.
Summary: I couldn't decide between these and px100 II so I ordered both to try out. I was looking for a lightweight headphone that I can use in bed when watching movies and playing games on my pad and a bit of radio listening.
Summary: I had two pairs of these and both times they lost the sound in one ear within months. Amazon were great and first replaced them, then second time gave me a refund. It's obviously a design fault but it's frustrating because I loved their portability and the sound quality was really good.
Summary: I've had two pairs of these headphones in 6 months, both suffering a similar fate. The sound produced by these headphones is outstanding, they're comfortable and effectively cut out background noise, whilst the closed back design makes them fine for commuting.
Summary: After getting through quite a few pairs of in-ear type earphones, I decided to buy this pair of on-ear ones, because I thought they'd be less likely to break and sound better. Well, I was certainly wrong about the former!
Summary: I'd give a much higher rating for sound quality, but while they're outwardly physically robust (my most recent pair look as new after a year of regular use) there are serious problems with the internal wiring.
Summary: Had two pairs of these now, last ones replaced in February 2011 as lost sound in one ear and same has just happened to the replacements. Great sound, but I expect a pair to last more than four to five months, which is what these have.
Build quality could be better, out lasted by the non-i version

Summary: The first one I received died on me - the sound stopped working in one ear. I got it replaced, but the second one died in a similar way in a ahort time, and I haven't bothered to return it again as I expect it to keep happening, because I keep the phone in my pocket and it forces on the connector.
Summary: Good overall quality, they have very clear sound and the microphone is crisp and clear as well. Although after about 2 months of normal usage the jack has started to work poorly, the microphone and remote control buttons no longer work and the audio cracks if moving the cable.
