Product details

Automatically tinted & UV-safe
Whether it's bright sunshine, a cloudy sky, or changing light conditions – the photochromic lenses automatically adjust to ensure clear vision at all times. Thanks to ISO-certified UV protection, your eyes are reliably shielded from harmful radiation. Ideal for everyday use, travel, and outdoor activities in any weather.

Sound with clarity
The open speaker design delivers rich sound for music, podcasts, and clear calls – without completely blocking out your surroundings. You remain aware of traffic, colleagues, or announcements while enjoying your sound. Perfect for use on the go, during sports, in the office, or wherever you want to stay active yet present.

Smart click instead of touch confusion
The intuitive control is done via three side buttons directly on the glasses – without the hassle of tapping on your smartphone. Whether it's volume, track change, call answering, or voice assistant: everything is at your fingertips with just one click. Simple, reliable, and perfect for situations where you need to react quickly – whether during sports, on the go, or in a meeting.

USB-C standard & quick start
Full power in a short time: with the included USB-C cable, you can fully charge the glasses in about 2 hours. After that, enjoy up to 6 hours of music, calls, or podcasts – without interruption. The modern USB-C standard ensures universal compatibility with your other devices, making charging particularly straightforward and future-proof.

Ultralight & secure fit
Weighing only 35 g – so light that you almost forget you're wearing them. Yet the glasses sit securely and comfortably, even during movement, sports, or extended wear. No pressure points, no slipping – just pure comfort. From the first ray of sunshine to sunset, they accompany you throughout the day without being a distraction.
