I recently purchased the QC35 headphones and am having significant Bluetooth connectivity issues while listening to music on a 2016 13" Macbook Pro w/ Touchbar. Both devices are updated with the latest software (QC35 = 1.3.2, MacOS = 10.12.5).
When pairing these two devices and listening to music, the longest I can go without dropped/static interruption is 10 minutes. In the worst case, it's happening every 60 seconds. I am using WIFI on the computer. The one constant I have noticed is that whenever the connection issues begin, if I look at my Bluetooth connection, there is a new device connected as "Broadcom Bluetooth Device" (see image below). If I do nothing, this will disappear on its own after several seconds, or, I can also disconnect it manually. Either way once the secondary Bluetooth connection is disabled the interference stops. Does anyone have any idea what's causing this "Broadcom Bluetooth Device" connection to interfere? Is it caused by the QC35 or something else?
