Ambient sound quality is pretty good. The sound quality from the Bluetooth connection to my phone isn’t great. Music sounds thin and I can’t find any good way to improve that part of the sound quality.
Let me start by saying that overall its not a bad product. My first complaint is that they're not rechargeable(change batteries after about 24hrs of run time). Secondly, is that the screen covering the speaker pushes against my ear(maybe thinker ear pads would help). Finally, I expected to be able to take calls on them, but my wife says my voice sounds really muffled.
