The PR-75a AutoSmart-Tuning Receiver from Comtek is ideal for auditory assistance and other personal communication. The receiver automatically tunes itself to the closest transmitter when it's turned on, so one receiver can be used to tune in to multiple receivers. The receiver runs on 2 AA batteries so it can work anywhere even when you're not near an outlet. The audio output jack doubles as an automatic on/off switch when earphones are inserted or removed.
Up to 100 hours battery life
