German headphone brand Sennheiser has released their newest True Wireless earphones, the Sennheiser CX True Wireless IEMs.


Sennheiser CX True Wireless IEMs feature the brand’s proprietary TrueResponse transducer which is designed and manufactured at the company’s headquarters in Germany and was developed for Sennheiser’s premium earphones.

The Sennheiser Smart Control App and built-in EQ allow for custom tailoring of the listening experience, whether notching up the intensity of music with the Bass Boost preset, relaxing with a podcast, or enhancing audio for a phone call. Bluetooth 5.2 compatibility and SBC, AAC and aptX audio codec support ensure wireless sound quality and management of Bluetooth connections via the Smart Control app.

“The CX True Wireless delivers truly superior sound at an accessible price point,” said Anton Zgurskiy, Product Manager at Sennheiser. “Featuring state-of-the-art technology and offering proven ergonomics, the earbuds have been developed according to user comfort studies. They also offer an outstanding personal audio experience that anyone can enjoy anywhere, every day.”


With 9 hours of battery life and up to 27 hours available when charging on-the-go with the supplied case, the Sennheiser CX True Wireless will keep going, and comfortable, all day. The ergonomics of the earbuds were developed according to user comfort studies. For a perfect fit in the ear canal that keeps the earbuds securely in place and effectively attenuates outside noise, ear adapters are provided in four sizes. The earphones’ IPX4-rated splash resistance offers additional peace of mind.

The CX True Wireless features an intuitive touch interface. Via a firmware update, the user can make the touch controls customisable, letting the listener define their preferred way of controlling audio, calls or accessing voice assistants such as Google Assistant or Siri. The charging case is similarly intuitive, with the earbuds automatically powering on when taken out of the case and powering down to save energy when replaced.

Using dual microphones on each earphone for better voice pick-up, the CX True Wireless optimises speech for calls and voice assistant access, even when using a single earbud. A convenient ‘role switching’ feature allows either earbud to be used on its own for added versatility. The Sidetone feature, which makes phone calls more comfortable by letting the user hear their own voice during calls, is adjustable via a slider setting in the Smart Control app.


The CX True Wireless will be available in matte black or matte white from the 8th of July for £119.99 / €129 (RRP).
