I have the Liberty Air 2 and so far I’m loving it. However, they face the same issue as multiple earbuds where the connection drops / stutters some times depending which pocket you have your cellphone in. This is because human body is a big source of interference and the Bluetooth antenna is basically stuck inside your head with this model design (the Pros, for example, stay outside due to it’s design).
The Airs 2 can work independently, however, when both are on, the right one is the master and the left one is the slave. So if I have my phone in my left pocket it cause the connection to drop.
I wanted to suggest to allow both earbuds to be able to sync with the phone or to allow us to choose which one is the master in the app. That way you could avoid this.
