I have had these for a couple years now and they sound great, are very simple to use, and only cost about $100. The one caveat is that they are not very comfortable after wearing them for extended periods of time. I’ve been meaning to add some cushioning material to the headbands on mine, just haven’t gotten around to it. Unfortunately, they don’t come with the required AC adaptor or RCA cables but you can pick those up on amazon as well for less than $10.
I was looking at this one https://www.amazon.com/dp/B001584QQU/ref=cm_sw_r_other_apa_0H0oybN5XX0NQ. The Q&A portion of Amazon mentioned each receiver can accommodate 3 headsets so I was picturing getting at least 3 receivers and seeing if I can grab extra headsets separate. I just don’t know if that would work well/if it would compress the audio making it unbearable.
