I use the Telex 5x5 pro III with a custom ear mold. It works great, pretty reasonably priced too. The only complaint I have, which I talked to telex about with no solution is the audible warnings are kind of loud when you have a custom ear mold. Other than that I have been pretty happy with it. My dad also has had one for the last 10+ years with no complaints. Any questions feel free to PM
