The receiver looks solid but the clip seems a tad flimsy, I'm satisfied with the battery life. The power/volume knob is reliable, however, a surge of sound upon turning teaches you to plug in your in-ears after the fact.
There is also a decent level of noise coming along with them, but I'm not sure If it's related to the receiver or matching transmitter.
The earbuds are anything but the best, but I did get some use out of them in a live scenario and they did the job. No sound Isolation and practically no bass, but I needed them to have the percussion and a clicker in my ear so they did the job they were required for.
The best part is that I can purchase several of those and have them all synced with the same transmitter if one is not too picky on sharing the same mix with other musicians. Might be a common thing for wireless monitors but I was happy with the notion.
Honestly, you could do worse, and for the price, you can't really do much better.
