Wireless TV Headsets technologies review: Their advantages and disadvantages
- Infrared TV headset : It’s the cheapest technology. However, the helmet must be in front of the receiver base to operate. If someone walks between you and the TV, the sound is muted. The range is 10 to 12 meters ahead. They are not compatible with plasma screeens.
- FM or UHF TV headset : More expensive, these TV headsets allow you to change room and even out in the garden. The transmission distance is up to 100 meters outdoors. They are susceptible to interference. Interference are cackling that may appear if the receiver is close to a mobile phone, a high voltage line, a microwave oven or other equipment producing waves: computer, internet modem etc. A thick wall (reinforced concrete or chained) can stop transmission. The selection and adjustment of frequency is more difficult (it is often necessary to choose a channel and turning a button like on the old radio receivers). So, it’s possible that you can hear the sound of neighbor’s TV.
- Digital TV headset 2.4Ghz : The lastest technology. It’s a hi-fi digital link (0 – 20 kHz) with an audit of data packets (transmitter and receiver communicate to ensure that no note is lost). Transmission distance is about 30m and 100m outdoors. However, a thick wall (reinforced concrete or chained) can stop transmission. This technology may be disturb by interferences. Pairing is automatic, no need key combination.
- Bluetooth TV headset : This is a similar technology to digital 2.4Ghz, suitable for telephony. It was first adapted for the transmission to mobile products, players… The transmission distance is usually less than 10m. Beware also of the frequency band. The wireless headphones that you buy must use a hi-fi system with a frequency of 20 KHz and not just telephone transmission (up to 4 KHz).
