Question: Does it include the AC adapter?
Document: It would work perfectly as a supplemental speaker for someone who is hard of hearing, especially with some of the poor speaker systems in todays newer TV's. I would suggest buying an AC adapter for the speaker so that you don't have to completely rely on the charger system.
Battery wont charge after the first week. Bought an adapter and keep it plugged in
Works great for someone with hearing problems. It has very good sound. The unit had a loud buzzing noise, but this was due to cables not completely connected into the TV on the back, once this was corrected, sound is great!
Works as advertised, no headphones, no wires, easy set up, easy recharge, it's a perfect solution. It's so excellent, we forget what it was like before we had it.
We have tried numerous speaker solutions & find this to be the best find, thus far. Have tried TV Ears, Bose speaker system & headphones. The only drawback for some users( might be)  that when the speaker is attached to our TV's we loose the TV set's speakers which are poor quality most often, anyway. That results with this SoundBox being the only speaker that functions. That is not a problem in our home.
We bought this to use in the kitchen and other areas of the house with no problems with sound reception. We have a surround sound system and my husband was able to hook it up with the purchase of additional cables to enable us to ear not only TV but also radio and DVD through the sound system. It's nice to be able to hear without blasting the surround sound system.
Very fast shipping and it was free. Works great and took less than a minute to install it. Does everything that was represented when I was looking to find a product like this.
This works as good as expected. I use it as a bedside speaker for my bedroom TV so that my late night TV watching doesn't disturb my hubby as much. I can turn the TV volume down and listen to the speaker right next to me. It's not great sound, but it's good for the purpose I bought it. The directions say that the unit will automatically turn off after 3 minutes of not receiving a sound signal from your TV. That's not the case.
This sound system is perfect to set next to a chair and help boost the tv sound. I have lost the hearing in one ear so I struggle to understand what it said. This helps a lot!
This is not a product for older people who are not electronically savvy. All I really wanted was a speaker to attach to the TV and sit near my chair. This is very light weight. You have to charge a battery to keep it going. We could not even get it to work with our small flat screen tv. I don't want to have to keep it charged for it to work. So am sending it back-definitely not for me.
Answer: Yep.
