XO Vision IR630P Universal IR Wireless Foldable Headphones - Pink Bluetooth Headphones for iPhone, Android, Car & Kids | Lightweight Portable Design | Perfect for Travel, Commuting & Car Entertainment Systems

These headphones work right out of the package in my Honda Odyssey 2006, which has a factory installed DVD player with IR transmitter. Some other reviewers complained that the product description didn't clarify that you need to either have a pre-existing InfraRed transmitter in your car, or have one installed.I have bought three of these headphones in various colors for my three kids, and they work flawlessly. They are more effective than the factory headsets at picking up the IR signal, causing less overall static and loss in volume. The factory headsets would lose signal in the back corner of the car, or if your head was turned, and the factory headsets only had IR sensors on the front (meaning that if the kids put on the headset backwards, it wouldn't work at all, which was a problem with our smallest 3-4 year old). These headphones can pick up the IR signal being forwards or backwards, and even if your head is turned sideways.The volume controls on these are less recessed than on the factory headsets, which makes it easier for kids fingers to find the volume, and they are a little louder at the loudest setting than the originals. Picky parents may not be happy with this due to prolonged exposure to loud sounds... but for me it means less of the kids complaining that me listening to the radio keps them from hearing their movie.These headphones do rotate their earbuds in, so they fit well in a seatback pocket, though rotating the earbuds does not turn them off. These headphones must be manually turned off by pressing a button on the headphone. There is some potential for batteries to be completely drained if the headphones are left on...but all of my kids have already developed good "remember to turn off" skills, and I haven't had one set of dead batteries resulting from headphones being left on. [Plus, we use rechargable batteries, so even if they die, we have backups in the car, and it is a non issue]These headphones have a much smaller diameter than the factory headphones, and fit the kids heads much more snugly than the factory headsets. Plus they don't have that annoying plastic strap that the original headphones had in our car, which made the headphones uncomfortable. These headphones snugly fit my 4 year old in the smalles setting, and can extend to fit my adult head.Several reviewers have complained about cheap quality. I think these are made extremely well, and haven't had any defect show itself in the 6 months since we've owned these. My kids got into a fight over one pair and despite pulling and tugging they weren't broken. One of the leather ear phone covers was pulled off, but I was able to stretch it back on in a few seconds, and it has functioned perfectly since.I originally bought two of these for our car to replace two of the factory headsets which had broken, but after using them for several months, I bought more to replace the still working factory headsets because they are that much better. And at a price that is much much better than the originals.
