Hi, Bought my father some wireless headphones, his pc does not have built in Bluetooth, so I bought a Bluetooth adapter that is compatible for Win7. Iv set up the adapter with the headphones and all is fine, its finds both the adapter and the headphones for the adapter. Went on Firefox , then youtube, played a song, sounds fine. I then turn off the power button on the headphones, when I turn the headphones back on and connects to the Bluetooth adapter again all I hear is this random popping noise when playing a YT video. I also have the same setup with the same headphones for a different pc with the same Bluetooth adapter, and all is fine. I do not get the popping noise on my headphones using my pc Could it be interference? as his pc is close to a TV, Internet router, and some speakers including a sub woofer.
