If you want to watch TV or listen to music late at night without disturbing anyone then wireless headphones are a must. All you do is plug the transmitter to your TV/mp3 player/etc then scan for the signal with your headphones and that’s it.
The HF-500 can be used to transmit audio from most sources. It can be used as a monitoring device. It can be used as a mic for your PC. It can also be used to pick up FM radio stations.
When in monitoring mode you basically use its built in mic to send you the audio it picks up. Good for spying on people or as a baby monitor from another room.
In PC chat mode, it can be used as mic for your PC.
Hit the Scan button a few times and it’ll scan through radio stations to listen to.
I use these headphones primarily in the living room. My LCD TV is 12 feet away and mounted on the wall. Having a 12 ft wire across my living room is not an option. Wireless headphones are perfect for this.
The HF-500 comes with adapters to hook up to red/white RCA connectors that are on TV’s. It comes with a RCA to stereo 3.5mm connector found in most MP3 players. The transmitter can run on 2×1.5v AAA or a 4.5v adapter (not included). The headphones run on 2xAAA’s as well.
Sound quality is decent. It’s like FM radio so nothing spectacular. Sometimes there is a bit of static interference but nothing that is too annoying. I can walk around the house too. I can go to the kitchen and the audio signal is still strong.
It’s good enough for me for watching TV and playing games at night. For less than $20, it’s a bargain. If you want better quality, you’ll have to spend a few hundred. So I think for the price, it’s good value.
