My Motorola S305 headset sounds great with phone or music... when it plays. With my BB 9650 at 220.127.116.114, the signal will drop every few minutes for a few seconds and then resume. Disrupts the music considerably. The volume is great up to about 30 feet. The headset works perfectly with my wife's Droid X with no problems at all. The problem is obviously with the Blackberry. Can anyone suggest a cure? I love my BB and the S305. I'd like to make them compatible.
