Review Content I would buy this product again. My husband who is moderately deaf got the headphones and TV adapter for Fathers Day. He is now able to follow a drama, the news, or any talk show and know what is going on. The sound quality is excellent and the fact that the unit turns off when he takes the headphones off is just great. The TV unit is powered by electricity. Quiet at Night I use this product at night when the house is quiet. I try to stay as quiet as possible,which seems impossible when your trying. Before I had to keep it as low as possible,trying not to wake anyone or the dogs up. They have completely solved my problems. Thanks Wonderful Gift! This review comes from my son-in-law who is an enthusiast and thoroughly enjoys this headset! I purchased this as a gift for him and he could not have been any more pleased. I always rely on the purchases I make from Sharper Image to be of high quality and high standards. Thank you for caring about your products and keeping them a cut above!
