I bought this in october. I agree with other reviewers, the sound is definitely value for money you can read other reviews for that.   However, the build quality is terrible.    I took good care of it, only used it in the office. However, after 1 month, the Y splitter got loose and you can see the wires underneath. Also the connector between the wire and each headphone ear buds also got loose.   After just 3 months, the right earphone no longer works. Fine, I still like this headphone. maybe I got a bad batch, lets email Ostry. No response...

I am not sure how these got such rave reviews.   As background I've used DBA02 Sony XBA3 prior to purchasing these. I was interested because of its double dynamic drivers.   After receiving them, I was really underwhelmed. They lack in clarity, sound grainy, no high or low end. And worst of all, the left channel is like half the volume of the right channel.   Even considering the price they were not worth it.    This may be a quality control issue but I wouldn't take the risk again considering how hard it is to order this (shipped from china).
