I recently purchased Soundcore Life 2 (SCL2) NC headphones. They work fine with my iPhone 7 but when I connect to my MacBook Pro (MBP) running Mojave 10.14.6, the audio cuts in and out often and sometimes really bad. It took me some experimentation work to isolate the problem. I noticed that the interference goes away when my other Bluetooth (BT) devices are disconnected. I have both a BT keyboard and mouse connected to the MBP. I already disabled the iPhone’s connection to SCL2 to reduce unnecessary BT connections. Before discovering the interference issue, I tried several things, and none helped:
- Deleted the com.apple.Bluetooth.plist* file from /Library/Preferences folder. Also deleted com.apple.Bluetooth.xxxxxxxxxxxxxxxxxx file from ~/Library/Preferences/ByHost then restarted the MBP. (Instructions from here: https://www.idownloadblog.com/2016/02/01/experiencing-bluetooth-problems-on-your-mac-try-this/). That did not help.
- Checked and found the SCL2 is using the SBC audio codec. Added the AAC codec as outlined here (https://www.macrumors.com/how-to/enable-aptx-aac-bluetooth-audio-codecs-macos/) and restarted the MBP. The audio cutouts with the SCL2 got even worse. Switched back to the SBC codec and restarted the MBP.
So the issue appears to be an interference issue with other BL devices. This could be either signal interfence issue or more likely a firmware issue. This is pretty bad if the SCL2 cannot coexist with things like BT keyboard and mouse.
Has anybody else experienced these issues? Are there any workarounds? I got these headphones for general music listening use as well as to improve my BT audio setup when doing videoconferencing on my MBP. I really was looking forward to seeing these work but right now they are pretty unusable and would have no choice to return them back to where I bought them (Costco) if I can’t get this problem resolved soon.
