Consumer review by: Dan Davies (



I bought these to replace the headphones which came with my mp3 player - sound-wise these are far better although not especially comfortable and tend to come loose quite a lot. I'm thinking I should have gone for the Sony MDR-EX71, as they come with...

Extremely clean sound, decent midrange & bass for in-ear phones.

Not particularly comfortable after prolonged periods, tendency to become loose.
