The Sennheiser RS120 has an on/off switch as well as volume and transmission tuning controls. The base station doesn’t have controls. When you place the headphones on the transmitter base, it is automatically charged and a LED light indicates the charging status. The built-in transmitter control allows you to tweak the reception while the volume control lets you raise or lower the volume level.


The Sennheiser RS120 can connect to any device with analog audio output such as tablets, mobile phones, televisions, computers or audio components with an RCA audio output jack or 6.3mm or 3.5mm headphone socket.

You can also add extra headphones to the Sennheiser RS120 so that multiple listeners can listen to the same audio at the same time.


The Sennheiser RS120 weighs 8.1 ounces and it remains comfortable even after long hours of listening to your favorite songs.  This also means that you will not have any problem bringing the headphones with you anywhere.

The tuning and volume controls are both located on the right earcup, right next to each other. You might hear static when adjusting the volume due to this placement.

RF wireless headphones are not compatible with Bluetooth devices, so you can’t expect the Sennheiser RS120 to be able to connect to devices that use Bluetooth technology.

Since the headphones are not a closed or sealed-earcup construction, you will most likely hear some background noise like your vacuum cleaner when you are cleaning the house or the honking of your neighbor’s car outside.

Other than these downsides, the Sennheiser RS120 is an excellent wireless headphone that offers a comfortable listening experience.
