XO Vision IR620 Universal IR Infrared Wireless Foldable Headphones for In-Car TV, DVD, & Video Listening, Black, 4

I wanted wireless headphones for the sole purpose of watching TV at home. I did not want a proprietary system, as I wanted to use readily-available generic headphones that are cheap enough to throw away. I was not sure if the proprietary systems would be compatible with the commonly-available car-type headphones. In addition, most of the proprietary systems have low ratings, probably because of the included headphones. I wanted to use these inexpensive highly-rated headphones (which use AAA batteries, not proprietary rechargeables - a plus for me).Of course, you need a transmitter. I got this one: Infrared IR Audio Transmitter For Portable Headrest DVD Players For Wireless Headphone Conversion 12v For in Car Use. This unit is made for an automobile, so there is a problem. It does not come with a power supply (since it would normally be driven off the car's electrical system). It requires 12 volts.Most of us thrifty people probably have a good supply of the small power supplies in our junk box from previous electronics gear. Searching through my box, I found three or four 9-volt models, but no 12 volt models. However, checking the 9-volt supplies with a meter revealed that every single one of them put out between 12-13 volts (this does not mean YOURS will). All that is necessary is to splice the proper connector onto your (overvolted) 9-volt power supply or a 12-volt one (observing correct polarity, of course!).In my case, I did not know for sure this would work, and I did not want to cut the connector off the supplied one in case I needed to return the transmitter unit. I rummaged around and found the same connector on a different power supply, cut that one off, and used that. Now that you know this actually works, you might take a chance on cutting off the connector on the supplied cable and using that...BUT I AM NOT RESPONSIBLE IF ANYTHING GOES WRONG. For example, if you just happen to get a defective transmitter, you will then be unable to return it. I disavow any responsibility for what what happens or whatever losses you may incur.You can buy as many pairs of headphones as you want for however many people you want. There is no "coupling" of the headphone with the transmitter, so an unlimited number of headphones can be used.These headphones have a decent amount of bass response, and the sound is very clear (much clearer than the sound output from my TV). They are comfortable, and since they are not closed-ear, you can easily hear conversation in the room without taking them off.My system works great for considerably less money than systems advertised on TV. Since the transmitters usually last just about forever, the only expense going forward should be the occasional replacement of a (very cheap) headphone.

Shipped to Florida in 4 days. The headphones are packed in a retail, clam-shell packaging. It was not sealed like typical clam-shell packaging; no need for scissors or a box cutter, easy to open. It came with 2, AAA batteries. My expectations was not high and knowing full well that these may not be an absolute replacement for my factory equipped headphones from my 2011 Honda Odyssey in-car entertainment system. Once I installed the batteries, turned on the DVD player, and switched on the headphones, I was quite surprised and they do work right away without selecting IR channels sitting both middle or third row seats. Other reviewers noted static or sound cutting in and out. I replaced them with high quality, name brand batteries. Perhaps that solved the issue. The build quality is good. It has a nice, balanced weight; it did not feel like a 'dollarstore' headphones. Rotating the ear-cups felt borderline flimsy, however, they do lock in place. I may have to let my daughters know to be careful when using them.The ear-cup pads are made of foam. The density of the foam are equal as the factory headphones and have a snug fit. I feel confident that they will not loosen or fall out after extensive use. The ear-cups are adjustable for a perfect fit for my children and for adult users.The sound quality is good. I did a comparison with the factory headphones first. Then, I tried the XO Vision headphones at max volume. My sound test concludes that the max volume of the XO Vision headphones is equal to the factory headphones volume at '6 - 7'; max volume at '10'. The factory headphone volume at '10' is too loud and uncomfortable to listen. Honda did a good job of reducing the noise when the van is cruising at highways speeds. So, the sound output should satisfy listeners for my kids.Overall, the headphones work right away, no need to select an IR channel. The volume and sound quality is good. I will have my kids use these first instead of the factory headphones. Honda charges around $156 each!!! I'm very happy I took a chance with these. I wouldn't hesitate to buy 2 more pairs for the family and friends!
