What you are looking at isn’t a Bluetooth headset. No, this is Cybertheater, not Mobilewhack.
This is the Personal Television and Theater Amplifier, which can sync wirelessly to your TV or radio and boost the audio by about 50 decibels. It also has a directional microphone, amplifying the high and low frequencies for rich tones.
It is able to work for up to 18 hours on a four-hour charge, and it costs about $29.95.
