This Wireless TV Speaker from Hammacher Schlemmer would have been a great gift for my dad. It lets you have a remote speaker so that someone who needs a little extra volume can hear the sound without blasting the TV volume throughout the room. Plug the remote transmitter into the audio out on your TV, cable box, or satellite box, then place the remote speaker up to 50 feet away in the same room. The speaker reproduces 90-18,000Hz at up to a 90dB sound level. The cabinet holds two 5W speakers and has bass reflex ports. You can also plug headphones in so you can listen without disturbing anyone else. The Wireless TV Speaker is $149.95.
