Sound is excellent, but left channel started failing.
I don't know what to do about this set of IEMs for the price they're excellent but I've been using them daily for 7 months and the left channel started failing. They're not an expensive pair of IEMs but even so, they should be able to last longer than this. The left channel is noticeably quieter now and after swapping the monitors on the cable it's obvious that it's the left driver that has failed/is failing, not the cable or plug. There's no crackling or popping or static from the channel, it's just QUIETER so much so that it almost sounds mono. It can be mitigated by changing left/right balance, but that's not ideal. Guess I got a lemon.
