I agree. Ive been using wired iem until recently because for church use I cant afford to buy a good sounding system. I now use wi digital for iem for $200.. these are in the digital spectrum and sound quality is there. However, I have to handle these with care and certainly wouldnt hold up to touring with the build quality. Range is 50 ft line of site only and latency not nearly as good as line 6 products. It is good enough to get me untethered for worship services with great sound quality. (used with a headphone amp) as they need a hot input..Also to note, Ive already seen reports of the relay being reverse engineered for iem even in mono..!
