Serene Innovations TV-SoundBox Max review

The TV-SoundBox Max takes a different route to clearer dialogue: rather than processing the sound, it moves the speaker next to you. A base connects to the TV by optical, RCA or 3.5mm cable and sends audio over a 2.4 GHz RF link, which Serene says is zero-lag and reaches up to 100 feet. The speaker runs about 10 hours on its rechargeable battery and recharges on the base in roughly 3 hours. Serene says the Max plays louder and clearer than its Pro model, and it adds a carry handle for moving between rooms. A personal tone control lets the listener brighten voices, and a headphone jack allows private listening. What it lacks is the stepped dialogue boost of ZVOX, so it suits people whose main problem is distance from the TV or a partner who wants it quieter. At $139.95 it is fairly priced for a device made for hard-of-hearing viewers.

Who it is for

People who sit far from the TV, or who want the sound next to them at their own volume without blasting the room.
