Here’s one possibility for them: the
TV Hear Wireless Speaker. Simply put, it’s a wireless speaker that broadcasts sound from your TV. Instead of merely pumping the television volume, simply move the TV Hear
closer to you
and adjust its volume. Brilliant. You’ll need to connect a transmitter to your TV, though, so I wonder if it disables the television’s own speakers.
The TV Hear can be used with an AC adapter or 6 AA batteries. It has a 30 foot range over the 900MHz band (some cordless phones will probably interfere), and runs for $75.
