Well, ignoring the link issues, I think the audio is fine. All I care about is hearing the caller and the Supertooth is decent in that category. It has a large speaker for this type of device and even in my noisy offroad Jeep I can hear fine. A caller said I sounded 'funny' but I figured that was just because any speakerphone sounds different.

But I can hardly reccommend the thing. The latest issue is when I press the Pickup button to manually link to the BB, the Supertooth will start prompting me to "Say a Command".
