Just received today from Amazon and been using it since.. I have noticed that depending on sound mode I experience with these problems.
You can test with video call or playing below video on any devices:

Tried Noise Cancelling mode / Ambient Sound mode / Normal Mode
During a call with Microsoft Teams or any video call or playing above video from any device
Sound lost/stopped for a second / uncomfortable sound when switching between left & right sound.
This happens mainly when earphone is in Noise Cancelling mode & Normal mode. Ambient mode is totally fine..
it will be like either 1) one of side sound lost or 2) one of side sound stops for a second or two seconds then play again 3) when sound switching between it's very un-naturally switching sound (you hear boom sound when sound switching from left to right or right to left)
I did hard reset as well (like pressing button 8+ seconds after putting them into open case then re-connect)
I am using Dell laptop (new-ish one) and Galaxy S21 plus for testing, and both are like that.
Is there anything that I can do? or is this same experience for other people?
