User error huh? I must admit your responses often favor the seller vs the hard working people paying real hard earned cash. Some of us don't get products for free.....
I already had the left ear go bad. They replaced the left ear without replacing the right ear. Right after receiving the iem back from repair, the right ear went bad. In my decades of purchasing iems I never had this issue.
Every time something goes wrong, I have to take a trip to DHL which is extremely challenging for people like me. That's why people in my position research beforehand hoping we won't have to do a return.
Also, that's at least 2 weeks it takes to send them in for repair. I've purchased this iem back in December of last year, received in January and had issues every since.
Also, I've been very patient. I didn't say anything until my messages start being ignored.
More importantly, if the qa was done correctly in the first place, or at least the first time i sent it in for repair, this wouldn't be an issue.
