I use the HT820 headphones mostly with a 2003 Toshiba laptop. When the laptop and headphones connect successfully, the sound is fairly decent. The connection, however, is quirky to initiate and once initiated is interrupted with intermittent sound breaks occurring every 15 to 25 minutes. This is a bit annoying. Admittedly, this could be caused by the laptop as it is quite dated and did not come with bluetooth capabilities. I installed a USB bluetooth adatper and software (includes A2DP profile) from Targus (Model ACB10US). Perhaps an OEM bluetooth-enabled laptop would establish a better connection with the headphones.
