I use the PSM600 for 6 years.
It works well trs! Good potatoes, good transmission (up to 25m) and director Receivers solid and ergonomic. E1 The headphone nude over 110dB dynamic range! 2 frquences selectable UHF, limiter, XLR / jack (Combo), loop exits, racking adapter provided ...
It is more than 1700 today ... A bit pricey but the quality is pro l.
E1 The headphone alone is worth over 150 ... New models are also out in SHURE (E2, E3, E5).
I used 3 of scne and we gladly repeat if we play more!
