Wireless are great for some things but for zoom conferences Ive seen many people having to yank off the wireless and plug in headsets to be heard. A great feeling controller grip.

You need to understand that bamboo is a formerly living, fibrous material and not metal. As long as I don’t need to lift my arms above my head it’s good!

Placing the left bud back into the case and then returning it fixed the problem almost every time; I have never had to unpair/re-pair them.
