Sennheiser CX Plus Noise-Cancelling True Wireless In-Ear Headphones - Black


Take control of your audio experience with the customizable CX Plus Noise-Canceling True Wireless In-Ear Headphones from Sennheiser. Using dynamic 7mm TrueResponse drivers, the CX Plus earbuds are made to deliver rich audio and deep bass, which can be fine-tuned with a built-in equalizer by using the Sennheiser Smart Control app. When listening in public, use active noise cancellation to isolate yourself from distracting ambient noise, but if you need to let the world back in, simply activate Transparent Hearing via the integrated touch controls. These touch controls let you adjust music, hands-free calls, and voice activation of your digital assistant.

All-Day Power

On a full charge, the CX Plus headphones can give you up to 8 hours of audio, but an included charging case provides up to 16 additional hours. Simply place the earbuds inside and close the lid to begin recharging.

Clear Communication

When paired with your smartphone via Bluetooth, you can use the CX Plus earbuds to make hands-free phone calls or use your device's digital assistant, such as Siri or Google Assistant. Dual noise-reducing, beamforming microphones in each earbud focus on your voice, helping to ensure that you're heard clearly when having conversations or giving commands. An adjustable sidetone feature lets you hear your own voice during phone calls.

Workout Friendly

The splash-resistant IPX4 rating of the CX Plus earbuds lets you use them outside or at the gym without fear of rain or sweat damaging the earbuds.

Automatic Pause/Resume

Built-in sensors can detect when the earbuds are in or out of your ear. When removed, audio playback is automatically paused, and resumed as soon as you put them back in.

Use One Bud or Two

With microphones in each earbud, the CX Plus headphones can be used together or independently without sacrificing functionality. When using just one earbud at a time, you gain the ability to stay connected to your environment while maximizing battery life, as the unused earbud can stay in the case to recharge.

Additional Features

Manage Bluetooth connections, EQ, bass boost, firmware updates, and support via the Sennheiser Smart Control app
Four pairs of silicone ear adapters are included to optimize comfort
