Bought in May, in October one earpiece stopped working. Do not return under warranty, tk. a small piece was chipped off on the "clothespin" (at which point this was not the case when I handed it over, but you can't prove anything). When the maximum volume level is reached by adjusting the rocker, it emits a dull "blink" sound into the headphones, while turning off the main sound. Pairing is not operational.
