There is no movement of the headphones while I run and they are very comfortable to wear for an extended period of time.

Have owned Sony Wireless Headphones Model MDR-RF970R for several years and love them. Decided I needed another set for a TV in my office, so I got the newer version MDRRF985RK and they are perfect. I have difficulty hearing the TV and it is not the volume, but the clarity of the dialog. These wireless headphones are perfect. They block out other noise and make watching TV a pleasure again. I can go into another room and still hear the TV clearly. The set up is very simple. I have recommended these headphones to many of my friends who want to control the volume at which they listen to TV while others watching can tune the TV to a volume that is comfortable for them. I have never had a problem with static. It is great that the battery recharges as it sets in the transmitter cradle. Sony MDRRF985RK Wireless RF Headphone, Black Update. Now that I have used the headphones for a while I have to say that they are not as clear as the Model MDR-RF970R which were the first headphones I purchased. Wish I had gotten that model.

Two major problems with this headphone.
1. Very small transmittance range. If I walk to a different room just 30 feet away from the TV, the sound in the headphone starts breaking.
2. There is no access to the battery compartment. I contacted Sony customer service about this, and they confirmed that the batteries are not user replaceable. If I need to replace them, I have to send the headphone to the service technician. So their specs published on Sony official website is deceptive. It states that this headphone can use both Ni-MH and simple AAA batteries.
I would not recommend this product to anybody unless you are going to use it next to the TV and dispose it in two years when your original batteries go bad.

Update. After using it for almost two years I would like to change my rating from 2 star to 4 (maybe 3.5)stars. The problem with battery replacement still exists but my battery is still good and shows no signs of going bad so far. Hopefully it will last a few more years. The limited transmittance range is probably a problem of my house (other people have no complains). The quality of materials is good and the headphone is still looks like new.

Some reviewers on here seem too picky. Yes they are big (what were you expecting, Earbuds?!) Yes they work better if you have line of sight (not outside mowing your lawn). People, these are wireless headphones for under $100, don't expect to do laundry in your basement while listening to TV upstairs and not have static. That said, if you want great sounding, wireless headphones for watching TV in bed or on the couch, these are perfect. I picked these up because I liked the look and the price. Very impressed with the sound quality, like being in a theater! Crisp treble and great bass. I use them with my home theater and XBOX so I can play games while my GF watches her TV shows in the loft. I even hear little details in the sound I didn't hear before thru my surround. They cover your whole ear so it blocks outside noise as well. Yes, I can still make runs to the kitchen or bathroom with very little static, so these are mobile - within reason. Tips for use: leave headset volume on low to medium and turn up the volume on the sound source (this will eliminate the hiss), fully charge them first before use, don't have the stand next to your amplifier or router as it could disrupt the signal. Hope this helps.

This is an overachieving pair of headphones from Sony. The purchase price is low and the returns are substantial. Meaning, you get a lot for your money. Another excellent product from Sony.

These "cans" will work with a wide variety of sound sources. You can use the included audio cable to accept signal from RCA jacks or from a single 3.5mm minijack. An adapter is also commonly available if you want to connect to the larger 6.35mm jack on professional audio components. RCA jacks are typically what you would find on a home audio component, such as HiFi Receivers, CD players, etc. The 3.5 minijack, introduced by Sony in 1979 for the Walkman, is what you would normally find in portable audio (mp3 players, Walkman, iPod) as well as just about all computers. The larger 6.35mm jack is less common today, but are still present in some professional audio equipment. You will need to buy an adapter for use with the latter type of jack, the 6.35mm.

I bought this for use with my computer. I watch YouTube, listen to iTunes, and I also edit a lot of video footage. These headphones are much more than capable for all of those. The whole system consists of four very simple components: power supply cable, audio cable, base/charging cradle, and the headphones. Connecting the base to your computer is a very simple process. The whole process of connecting the base to the computer's audio jack and to the power outlet took less than a minute. After that, simply put the headphones on top of the base for the initial battery charge. The Very First battery charge will take 3.5 hours, just like with any other rechargeable battery system.

The sound quality is excellent. You could get fooled into thinking you are listening to a pair of higher-priced units.
