Comfortably Better Music HUAWEI FreeBuds 4 takes Open-fit Active Noise Cancellation to new heights, incorporating all-new adaptive ear-matching technology for even greater audio immersion. The open-fit design allows air pressure to stay equalised, while ensuring important environmental sounds can still be heard — for a safer, more comfortable wearing experience even after long hours of use. In Tune with You Every ear is different. That’s why HUAWEI FreeBuds 4 uses adaptive ear-matching technology to detect your unique in-ear shape and how you wear the earbuds, then intelligently selects from a variety of noise cancellation modes to achieve optimal low-frequency sound reduction. A New Sphere of Listening The perfect-circle charging case is designed to fit right in your palm. And now even smaller and lighter, it slips seamlessly into your pocket, for an easier way to take your music with you. Sounder Fit The earbuds are ergonomically moulded to precisely fit your ear, for a shape that feels right every time. And at just 4.1 g each, they’ll sit naturally and comfortably in your ears, offering an almost weightless way to deeply enjoy music. Hits the High Notes The large 14.3 mm LCP dynamic driver inside each earbud is what helps HUAWEI FreeBuds 4 achieve their extraordinary sound quality. Boasting a frequency range of up to 40 kHz, they’ll let you experience the soaring melodies and rich timbres of all your favourite tunes. Let’s Bass it Better bass needs its own space. Each earbud is equipped with its own bass-enhancing power engine for greater diaphragm vibration, generating impressively deep bass you can really feel.
