While I can hear clearly with this headset and listen to music, no one on the other end can hear me speaking to them. I'm disappointed since the description states it is compatible with all 2.5 mm phones. I have a Huawei Ascend cell, and it's hard to find headsets that work with these phones.I'll keep these as a spare to listen to music, but I'll just foot the $15 for the correct headset for my phone.
