I guess I have an abundance of riches and shouldn't complain, but I still do. I have a small home studio with half a dozen guitars, 3 amps, a multi-effects pedal and an audio interface for recording. I am fed up with trailing cables all over the room, tripping over them and having to coil them all up and put them away when I am done.
The Airborne almost completely solves the problem and my little studio is now clutter-free.
It just works! Choose guitar and an amp, plug the transmitter into one and the receiver into the other, turn them both on and off you go. It is fantastic to be free of cables.
The Airborne looks quite big compared to the Line6 or Boss equivalent but in practice it plugs conveniently into every piece of kit I own and does not get in the way whilst playing. The only thing that is less than perfect is when plugging it into my Tonemaster Deluxe, with the amp's control panel on the front, the Airborne has to be plugged in with its back panel facing out. It's a purely aesthetic problem.
I have had no problem connecting any piece of kit. The sound quality is the same as using a cable. I have two electro-acoustic guitars with pre-amps, and they both work fine. I don't know if they count as active pickups. The first time I used the Airborne I had a couple of glitches when playing, literally for a second or two each time, but have had nothing since. The wifi router is in studio and I have experienced no drop outs so far.
I can't comment on the battery life or charging time yet but the two-way USB charging cable is quite convenient. A docking station would have been nice but I can build a simple substitute - a block of wood with two holes in it.
I highly recommend the Airborne. It does everything I need and is a fraction of the price of the Line6 and Boss alternatives.
