Sennheiser RS 275 TV Headphones

The Sennheiser RS 275 TV wireless headphones have a closed-back, over-ear design with a practical headband. This model does not use active noise cancellation, but instead relies on the passive isolation of the earpads. They connect to audio sources via Bluetooth 5.4, an analogue 3.5mm jack, or a digital USB-C connector. The integrated battery provides up to 50 hours of use on a single charge for long TV viewing sessions. The set also includes a desktop transmitter that doubles as a stand and power source.

Sound and Tuning

The headphones use 37mm dynamic drivers that provide a frequency range from 6Hz to 22,000Hz. Listeners have four sound profiles available to customise the content being played. Virtual surround sound creates an immersive three-dimensional effect right in your living room. In addition, the Speech Clarity function brings the spoken word to the forefront, so dialogue remains intelligible even with loud sound effects.

Battery Life and Durability

The headphone battery offers up to 50 hours of use on a single charge for long, uninterrupted binge-watching sessions of your favourite shows. Charging is convenient via the USB-C port on the headphones, from the transmitter, or from a standard home charger. The replaceable battery lasts for up to 12 years of regular use. Thanks to fast charging support, you can get the power you need for further use in a very short time.

Comfort and Design

The closed-back, over-ear design effectively dampens ambient sounds while preventing sound from leaking to other members of the household. A low weight of just 200g prevents fatigue even during long movie sessions. The soft earpads with a pleasant surface do not press on the ears and maintain an optimal temperature. If they become worn, you can easily remove them and replace them with modern parts.

Controls and App

You can make basic volume adjustments using the buttons located directly on the headphones. For detailed adjustments, use the Sennheiser Smart Control Plus App for Android and iOS. The mobile app offers advanced adjustments to the frequency response and balance of the left and right channels. In the interface, you can also activate noise cancellation or set safe volume limits.

Connection and BTA1 Transmitter

The included BTA1 transmitter connects to the TV via an optical cable, a classic 3.5mm jack, or a modern HDMI ARC interface. The manufacturer has already paired the headphones with the transmitter at the factory, which simplifies the initial installation. The wireless transmission uses modern Auracast technology with a signal range of up to 50 metres. This allows you to connect multiple compatible receivers to one transmitter and share the audio with other people.
