About Sony

Approximately 900 million of Sony’s devices are in use in the world today. To achieve this feat, Sony never wavered from the vision of its co-founders, engineer Masaru Ibuka and physicist Akio Morita. From its beginning in 1946, Sony has always positioned itself on the cutting edge of technology to continually break new ground, from the portable transistor radio in the ‘50s to the color television in the ‘60s to the PlayStation video game console in the early ‘90s. Along the way, Sony also co-developed a range of industry standard formats, including the CD, DVD, and Blu-ray Disc. Not content to only store and play media, the company also produces movies, music, and television and is responsible for acclaimed films and shows such as The Social Network and Breaking Bad while representing artists as diverse as Adele, Bruce Springsteen, Usher, and Milton, a baritone humpback whale.

We have used other RF headphones for listening to the TV. These are the best. The interface always works well and is simple to use. The phones are light and very comfortable.

Works great, easy to hook up, but make sure you put it back on the charger after every use or it won't work next time.

I was under the impression that they were bluetooth and that they would work with any device. Which was not the case.

Sound was okay but the size of the headphones are way to big and they are also heavy. Good for studio sessions but not Day-to-day use.

Yes, these were for my husband and he is really enjoying them - great sound experience. He had a different kind before that were not "over the ear" - they had small foam pads that fit "inside the ear", so this has really made his watching TV a lot nicer! Thank you!
