Had it for about a month now, and I?m hoping that it doesn?t stop working. However, after complaining with my friends several times, he suddenly found my chins position looks strange once he came in to wake me up. Other types would not be so forgiving. Believe me I have tried many wireless headsets nothing beats this. So Im now in my second "return/replace" effort. Overall, up to the KZ standards, and different enough to warrant a second look with nodding approval glances. Some songs sound fine at 128kbps, others sound significantly better at higher qualities. Normally, I love TEVA and wear their sandals often. FIVE STARS all around???? Boom connects to the boom app, and to the other boom speakers that I already own.
