Put simply, it seems to work right out of the box as advertised. I bought two and tested them as soon as they arrived, no problem. The sound quality in the headphones is better than I expected and is actually quite good. The only thing that differs a bit is the clip that attaches part of the cable to the clear plastic of the earcup and receiver: it's funky in shape and a little fiddly. Putting pressure on him, pressing him against my shirt. The spring clip is ok and works (cheap earplugs from other manufacturers have already broken for me) is ok, just a bit awkward to use. If I buy more compatible radios I will buy more of these headphones.
