I have tried several professional Bluethooth setups for my PA setup. This one stays. Much cheaper than Radial, much better than most cheaper options. Easy and, most important, reliable connection. It never failed me. The antenna does not come off, making it a bit cumbersome. But it gives stable connection at a surprisingly large distance (50+). Sounds good, easy level adjustment, sturdy balanced connection. Need its own powersupply, it could have been phantom powered.
