The Amplicoms TV SoundBox is a portable wireless TV Speaker that brings TV sound right in front of you. There will be no more straining to hear your TV from far away as the volume control works independently to the TV speaker, allowing you to turn the TV volume down or completely off. The 2 high fidelity Class D speakers deliver loud, lifelike sound and crystal clear dialogue and the adjustable voice enhancing makes each word fully intelligible and easer to understand. The transmitter also services as a charging dock for when the receiver is not in use and once fully charged, the TV SoundBox will provide up to 8 hours of listening time. The easy plug-and-play installation means you can get straight into watching TV with the 3-level tone adjustment for optimal selection according to personal hearing profile. If no signal is detected for 3 minutes, the TV SoundBox switches off automatically to conserve receiver battery power.
