Very Disappointed
I only bought it yesterday and returned it this morning. The picture on the package shows a stand holding headphones with a large TV mounted in the background. What it fails to show is the wire running from the TV to the stand and another wire from the stand to an outlet. It ruined the entire look of our living room. This product is not at all practical with a wall mounted TV. It would probably be fine if your TV is sitting on a stand that has room for the headphone stand.

Poor design
I just ordered a replacement pair from Best Buy. I am relieved I purchased the protection plan. The bracket that held the left earpiece broke one month into the lock down. Two months later they wouldn't charge. I returned them yesterday and my replacement one's will arrive tomorrow. They were not in stock at that store. I also purchased the protection plan again. My original pair broke 2 months pat the original warranty.

I am on my second wireless headphone. After awhile the connection with headphone and bass doesn’t charge, About 2 years and they are both shot. What do I do now, just spend another $130.00. If the product would be made properly this shouldn’t happen. Maybe I’ll have to try a made in America product

Great product!
Bought these for my dad, who has difficulty hearing, 2 years ago. He finds them very easy to use. Mom and I are able to listen to the tv at a lower volume or muted if we don't like what he's watching. Dad only has use of one hand so after years of using them, they have cracked. The battery is now not lasting as long. Looking to replace just the headphone and battery.

Sony should do better.
I’m ready to return them. You have to unplug them from tv if you want tv speakers on and when you plug them back in it takes several attempts to get them to work. Too difficult. It should be easy. And if you can’t get it on the fixed audio option the sound snaps and pops occasionally.

Great Sound/Poor Quality
I love the sound in the headphones and clarity of voices. The only problem is that whenever I touch the volume wheel located on one headphone the volume in it dies and I only get sound out of the other side. I have written this up to the Sony service department. They made suggestions that were useless and I have not heard from them since.

I bought these 4-20 to replace a previous set of Sony RF headphones I had used for about 10 years! I received great service from them.
The new ones are even better. More comfortable and easy to set up.

Headphone - WH-RF400 User Manual
Poor user instruction to setup RF & A/V connections, e.g.:
1.) Do not indicate when we should do the RF connection with TV.
2.) Is it suppose to do V/A connection while it is charging?
3.) How long the charging takes?
4.) How often we should charge the headphone?
I was not able to find the above issues in Sony online support!!!!!!! Therefore I’ll give “F” grade for Sony’s user’s manual.

Poor Sony’s Technical Support - I tried to call for support and it was down because of COVID19 but the Technical Support could work from HOME like all other companies in US.

Are they surround sound?
A shopper on Feb 6, 2020
  Thanks for your question. While designed and designated Home Theater Headphones, there are only two speaker element per ear. They to not process for surround sound.
Note that some manufacturers of home theater receivers may include surround effects for stereo headphones. Yamaha surround sound receivers have a feature called Silent Cinema which creates surround effects to connected headphones plugged into the front panel headphone jack.
