The Sennheiser RS 160 headphones are a pair of wireless headphones that came with rechargeable batteries when I purchased them months ago. They have a detachable cable that comes with a 1/8 inch connector. There is a digital volume control and a mute function on them as well. The audio comes through these headphones very clean for them to be affordable and wireless. I have used many different pair of wireless headphones in the past and each time I get a different feeling from them. Some of them have the issue with not delivering the clearest sound especially when working with music and not just listening to music. These do not do that, the sound quality is very clean and crisp.
The RS 160 headphones also have a “multi receiver” mode that will let the user have up to 4 different headphones used on the same audio source. I do not have 4 of them hooked up at the same time but I do use 2 of them at the same time and it comes in handy depending on what I want to use them for.
Setting up these headphones is very simple; all you have to do is plug up the audio outputs to the system that you are listening from. The RS 160 headphones are also very durable and seem like they will last a long time. The battery charge also last for a long time which is a huge plus for me because nothing is worse than wanting to use them and the batteries are dead! These headphones have a good frequency response of 22 Hz to 19.5 kHZ and they are circumaural headphones meaning they go around the ear.
I am a huge fan of these headphones, I have gotten rid of a lot of other headphones since I started using these and they eliminated the cords that are all over my studio at home. Being that some of my headphones are all the way on the other side of the room, I would have cords going everywhere. I recommend getting cordless headphones. These are not inexpensive but they are worth the 200 + dollars to have these quality.
