Only 8.1 ounces of weight make this headset lightweight and comfortable to wear. A supra-aural design (the earpads sit on top of your ears) is used for the ear cups. Over time, you can replace the ear cushions. These earphones offer a comfortable fit and plenty of breathing space because of the material. While noise cancellation can be effective, it is not as efficient as headphones with full-coverage ear cups.

This device requires a transmitter to function; therefore, it is an essential component. Because it is designed stylishly and beautifully, it will look great with the rest of the decor in your home. For optimal performance, keep the transmitter in an ideal location.


A switch on the Sennheiser RS120 activates the unit and controls the volume or transmission tuning. There are no controls on the base station. An LED light indicates whether the charger is charging once the headphones are placed on the transmitter. You can tweak the reception with the built-in transmitter control while adjusting the volume by turning the volume knob.

Sound Quality

It has also been designed with an easy-to-use charging system. You can recharge the Sennheiser RS120 by placing it on the transmitter base and charging it with AAA NiMH batteries.

To save battery life and power, the transmitter shuts down automatically 5 minutes after the source of audio is turned off. This headset has a range of over 300 feet so you can use it in any part of your home.

An integrated stereo RCA-plug cable is accomplished by connecting the transmission base to the audio source’s RCA line-out connections.

Using this device, you can get fantastic surround sound in the high and mid-range bass. The only drawback is the hissing sound when the transmitter is placed near another electronic device with remote control. Even though this is inconvenient, it is simple to fix: keep your transmitter away from such devices.

Thanks to high-frequency radio technology, users can tune into multiple frequency channels manually. Moreover, with a frequency of 900 MHz, you can rest assured that you will not interfere with other media. The sound and quality of RF technology are similar to that of infrared. Bluetooth devices can switch between channels, but RF can’t.
