TrueResponse Transducers

The superior sound of Sennheiser’s new CX Plus True Wireless earphones is a world apart – at an accessible price point. This is made possible thanks to the clarity of its German-engineered TrueResponse transducer, an acoustic system that brings audiophile technology to everyday listening. Developed for the audio specialist’s premium earphones, this bespoke acoustic system delivers high-fidelity stereo sound with deep basses, natural mids and clear, detailed treble.

Be in charge of the perfect sound

Immerse yourself with Active Noise Cancellation or stay in control with the Transparent Hearing mode.

The Active Noise Cancellation function ensures that listeners do not miss a note, allowing them to experience all the clarity, detail and thrilling bass without distractions – even in noisier environments.

Meanwhile, the Transparent Hearing feature makes it easy to focus on external sounds when desired without the need to remove the earbuds. This feature is particularly useful in letting outside sound in, so users are more aware of their surroundings.

Everyday life, simplified

​Thanks to the customisable touch controls, every interaction, touch, and moment shared with the CX Plus True Wireless can be conducted effortlessly. Users can even tailor bespoke commands to ensure that controlling audio, calls and accessing voice assistants is both convenient and intuitive. Each earbud is equipped with a pair of dual mics that optimises speech for calls and voice assistant access to ensure crystal clear voice pick-up. The independent earbud use allows the right and left earbuds to be used individually or as a pair.

Another intelligent feature, Smart Pause, has been developed with the fast pace of modern life in mind. It automatically pauses audio when the earbuds are taken out and instantly resumes playback when replaced. The earbuds also automatically power up when removed from their charging case and switch off when put away, so they are ready when you need them.

A high-tech listening experience

The CX Plus True Wireless also offers the latest connectivity options: Bluetooth 5.2 compatibility and SBC, AAC, aptX and aptX Adaptive codec support for high resolution, low latency audio that syncs perfectly with video content. Bluetooth connections can be easily managed via the Sennheiser Smart Control app, while the built-in EQ delivers a personalised audio experience and a thumping Bass Boost preset.

​Designed for all-day enjoyment

All Sennheiser’s True Wireless earbuds have been developed in line with the latest ergonomic research, and the sleek, smaller design of the CX Plus True Wireless guarantees fatigue-free all-day enjoyment. The compact earbuds also securely fit in the ear canal, so they stay in place when listening on the move. Optimal comfort is assured thanks to the four-size selection of silicon ear adapters, which add further passive noise isolation to complement the earbuds’ ANC.

With IPX4-rated splash resistance, listeners can enjoy the CX Plus True Wireless wherever they go. And, as life doesn’t slow down, the CX Plus True Wireless is ready to keep pace with its long-lasting battery and portable charging case, providing an impressive 24 hours of playback time.

Control at your fingertips

Have everything under control from audio and phone calls to fast access to Siri and Google Assistant with the customizable touch controls.

Use the Smart Control App to adjust your music, voice assistants, and calls to your liking and much more. Fine-tune your listening experience by customizing your sound and settings. Opt for Active Noise Cancellation, Transparent Hearing, the equalizer presets and Bass Boost.

Along with the personalization features, the app provides battery status, a Quick Guide, firmware updates and a podcast mode for optimized speech.
