Was hoping with 3 BAs and advertised better reinforcement of low-end, that I'd use this in a band but it is too weak in the low-frequency range, and annoyingly overly crisp in the high-frequencies. Low frequencies are not much better than cheap earbuds I bought for my phone. (FYI ... It will need much better sealing tips for isolation, which I expected -- that's not a ding on the product.)

Perfect addition to playing live. These helped tremendously!
