I just stumbled across this and have no business interest or experiences with it, but it was intriguing to consider if you want to add Bluetooth capability to your L1s or into a mixer channel. I’m sure there might be other devices like this out there, just thought I’d pass this along. I’m using my S1s Bluetooth more, but wouldn’t mind adding something like this to my L1 setup.
I've used a very inexpensive BlueTooth receiver (many less than $30) plugged into a channel of my QSC Touchmix Mixer (adapters to 1/4" Stereo input) before I switched to the Bose S1 Pros with bluetooth built in.
