Product details

Silence everywhere with ANC. Whether in the office, train, or airplane – active noise cancellation reliably filters out disturbances. This way, you can enjoy music and phone calls in the best quality, completely undistracted.

Immersive sound. Rich bass, clear highs, and precise details bring your songs to life. Thanks to interchangeable ear tips in S, M, and L, everything fits perfectly – for sound that completely immerses you.

Clear conversations. Multiple microphones with noise cancellation ensure that your voice remains understandable even in loud environments. Perfect for calls on the go or in a home office.

Long battery life. Up to 5 hours of music per charge, with the charging case even 20 hours. The included USB-C charging cable makes recharging easy – a charger starting from 5W is optionally usable.

Stylish design. Elegant surface, precise craftsmanship, and modern colors make the earbuds a premium accessory. Comfortable for everyday use and a real eye-catcher.
