Wireless headphone systems for cars, caravans and motorhomes are more popular than ever. Connecting wireless headphones to the music, DVD or gaming entertainment system in your vehicle is a great way to ensure everyone on-board gets what they want.
Before you make the choice about the wireless technology to use for your cordless headphone system it’s important to understand the differences. Below is a brief summary to help you make the right decision.
Infrared Wireless Headphones
In-car headphones that use infrared wireless technology are the best way to avoid electromagnetic noise problems, but does require more planning than an RF wireless system. Think carefully about the placement of the wireless transmitter when planning the infrared headphone system for your car, as any physical objects between the transmitter and headsets will cause audio drop outs.
Pros:
- Less prone to interference from nearby electrical/electronic equipment than RF wireless.
Cons:
- Infrared depends on line of sight link between transmitter and headsets – audio will drop out if link is broken by physical obstructions.
- Range limited to 5 metres – normally not a problem in automobile environments.
Analogue RF Wireless Headphones
Radio frequency (RF) wireless headphone systems are the first choice for many due to the fact the transmitter can be placed in a concealed location with no need for a line of sight link between wireless transmitter and the headphones. With RF wireless you can even get out of the vehicle and continue listening to the audio without interruption – perfect when installed in a motorhome or caravan.
However, cars can be electrically noisy environments and RF wireless signals are susceptible to interference from electronic equipment that is not well shielded. The only practical way to check if your vehicle is emitting RF noise that interferes with wireless headphones is to try it out. If you find you are getting interference then you will need to track down the source and fix it.
The possibility of interference from other wireless equipment is also present with RF wireless. Recent changes in wireless headphone frequency bands (especially the introduction of the 2.4Ghz band) means there is now more distance between consumer wireless signals, resulting in less chance of interference.
Pros:
- Long range between transmitter and headsets – signal can go through physical obstructions – no need for line of sight. Headphones can continue to be used outside the vehicle when parked.
Cons:
- Susceptible to interference from nearby electrical/electronic devices that emit electromagnetic noise, e.g. dashboard electronics, car computer, alternator, fridges, microwaves, low voltage lights, etc.
