Just got Kensington bt headphone from ups today and paired them with my 8900 and audio seems to be playing only out of the left earphone. I checked all of the settings on the berry and everything appears okay. The controls on the hs work fine with play pause track controls but no audio. I have the berry paired with a nokia bt stereo speaker set and worx fine so I'm assuming it is defective headphones but I was wondering if anyone had any input. Thanks in advance.
