Review: Reuse the IR headphones from the van in the house. - We had bought 2 Simolio headphones for the video system in our Sienna. After we sold the Sienna, we saved the headphones and wondered if we could reuse them at home. With this IR transmitter and an additional optical splitter, we can watch TV at home using the IR headphones. It works great. The sound is clear, and we can each adjust our own volume levels to our preference. When the grandkids are visiting, they can watch TV with the headphones and not bother the rest of us in the room. Very happy with this purchase.
Review: Perfect for a room or car! - This Simolio digital transmitter with a 4 pack of the Simolio DVD wireless headphones is perfect for our living room which is open to our dining room. We are retired and often have other couples over. The ladies love to play cards or board games and whoop it up with cheers and laughter. Us guys would rather watch a sports game or a good "macho" movie. In fact I bought TWO of the 4 packs of headphones and we can use as many as we need. I must point out that while this works fantastic for us being right in front of the TV, the signal is not intended to reach the headphones if we step away from the immediate area. But we don't care. The audio is flawless and clear and all I am doing is running a mini-stereo cable from the headphone jack on the back of the TV. From the TV to the transmitter I could use an optical cable instead of the mini-stereo cable. But, it is perfectly clear just the way it is. A couple of us are even a bit hard of hearing. With the TV speakers turned all the way down, we can each adjust our own headphone as we like. The quality of all the items is very good and (even though I don't need them) cables are included for everything. The transmitter comes with a power transformer (even a separate one for a car cigarette lighter). The only thing you will need to add is 2 AAA batteries for each headphone. I am really happy with these items and would gladly recommend the digital transmitter and headphones.
