Sony Wireless Radio Frequency Headphones (MDR-RF985RK)

HT Models

 Home-theater headphones—wired or wireless—are built for comfort  and audio fidelity. Wirelessmodels use IR (infrared),  RF (radio frequency), or  Kleer uncompressed RF  technologies. IR units have  a reputation for resisting  interference, while the two RF technologies may allow you to listen to audio from another room.  

Transmitters

 Home theater styles of wireless headphones generally come with a transmitter. This AC- or battery-powered unit receives audio from your HT  device(s), such as your A/Vreceiver, and sends it wire- lessly to the headphones.  Some models support multiple headsets, so several  family members can enjoy  the same program quietly.

 Features

 Some transmitters double as docking stations for the headphones, making it easy to recharge their batteries. Speaking of battery life, you want a set of headphones that will last through several movies  if necessary. And if you  plan to use the headset from a distance, make note of its range for usage, such as 100 feet. 

Comfort & Sound 

Choose a set of HT headphones that you find comfortable. After all, you don’t want to have to take them off halfway through a big game or Harry Potter movie. Likewise, try several models to see which  ones sound the best to  you. To this end, you’ll find that some models employ sound enhancement technologies.
