I bought these primarily due to the low price. I was a little worried when they arrived - generic Chinese packaging, instructions that could be much clearer. Once I got them hooked up to the computer (under 1 minute, plug them in) and finally got the headphones picking up the signal, it's been smooth sailing. The headset is pretty lightweight and comfortable, the signal reaches all rooms of the house. Each part of the unit requires 2 AAA batteries, so be sure to buy 4 batteries at the same time.Buy Wireless Rf Headphones for TV VCD PC MP3 MP4 CD DVD Ipod come with 3.5mm to 2.5mm adapter w/transmitter Fm!
