My missus bought me a pair of these as her brother recommended them.

I must admit I was quite impressed by the sound that they produced (not produce any more though). The sound is on the bassier side of all the in-ear headphones I have owned. This suits really well with rock or dance music but when the volume is cranked up the sound did become quite distorted which after a while became distracting.

The reason for the past tense is that they only lasted for 2 months from first use on the commute to work and back (so 90 minutes per day in total). The first thing to go was the sound in one ear intermittantly than 2 weeks later total loss of sound in that ear no matter how much wiggling I performed.

They came in a nice little zipped case which I have retained for use with other earphones

I would recommend Sennheisers which seem to last forever although the sound they produce is more mellow (middle of the road) and the sound does not become distorted
