bluetooth volume

[Airborne Lee]

Ok guys, I have been searching for days and not found a clear answer.

My Sprint iP-830 volume on bluetooth sucks. My earpiece and speaker volume are great. Clearly it is not the bluetooth earpiece itself but the phone setting.

I am on my 4th bluetooth headset. All are VERY loud on my other phones but not my iP-830. I see many hacks but none specify they are for bluetooth or specifically for my phone.

Does this one work on the Sprint version iP-830W?

Hack for louder ear piece volume for verizon.
