Amposo Wireless System

That ad comes up every day on FB.
I can not speak for the product, but I hate their advertising. They write copy like this is a revolutionary product, and no musician has ever gone wireless before. Pandering to non-musicians....huh...
For the same price you can get a XVIVE which you can try in the music store, and has a warranty. I still don't trust it, but at least it's a music product marketed to musicians.

 

6 ms of latency = no thank you from me. My Line 6 G70 does 1.5 ms so I'll stick with it, even though it's bigger.

 

Apparently the latency is 6ms at its maximum range of 75-ish feet. The latency at short range is around 2.5ms according to their support people. I didn't notice anything at 6-10 feet.

I bought one and don't notice any compression or distortion. It has good headroom with my active and passive basses (MM type preamp in the active). So far, I'm pretty happy with it. There was a tiny whine when I sat at my computer LCD monitor, but it was dead quiet at rehearsal.
