ventman Just a word of advice. I tried several Bluetooth devises, they all ended up having drop-outs while out gigging. Embarrassing to say the least. I ended up with a cabled, good quality USB-C to 3,5mm adapter. I have a brand called Linocell. It is much more robust than apple's own, which also works fine btw.
