Hey all, I've recently become aware of this Audiofusion™. They are offering wireless IEM system that uses your (currently) iOS (soon to include android) mobile phone as the headphone amp/output and controller. All the audio is streamed over wifi and looks to be a pretty promising solution. A house of worship muso showed him using it in practice and it worked well without any noticeable latency. Just wondering if anyone has tried it or something similar?
