Has what seems to me like over-emphasized highs. Can be excessively sibilant.
Hard snares like those in "Money for Nothing" can be painful.
Excellent fit an finish at the price point. I'd like to see this kind of build quality combined with the sound profile of a pair of IEMs like the QKZ KD9.
A few weeks later: I have been using these at work and they aren't too bad.
