Boss Audio HS-IR Wireless Headphones With Infrared Transmitter

The negative reviews above are based on ignorance. This product is intended to be used in a vehicle. All car electronics are sold this way as they are intended to be connected to the vehicle's electrical system. If you know what you're getting and how to use it, this product fits the bill quite nicely.

As it happens, I didn't want to use this in my vehicle. I connected it to a 12-volt power supply I had sitting in my closet and my kids use it on the computer. Now they can play their online games and watch movies without bugging me and the missus. Of course, I can still easily use it in my vehicle should I choose to do so.

The headphones are a bit flimsy but I didn't expect much for the price. This is the only reason I didn't award 5 out of 5. Research indicates that replacing the headphones when they eventually break will not be difficult or costly (Wal Mart sells a kid-friendly set -- perhaps a bit more durable -- for ~$25, for instance).

The headphones use 2-AAA batteries in each set. The kids naturally forget to turn them off when they're done using them. The batteries haven't died yet -- it's been 3 weeks -- but when they eventually do I'll probably replace them with NiMH rechargeables.

Sound quality is a bit lacking; I assume that's due to the limited bandwidth offered by infrared. I also have a pair of Bluetooth wireless headphones (Logitech FreePulse) and they have much better frequency response but even they aren't quite as good as wired. You have to expect a trade-off for going wireless, of course. For the kids' needs it's more than adequate.

Overall, if your expectations are realistic, there is no reason this product shouldn't be more than satisfactory.
