So eins verkaufenBeschreibung
The OpenJump is a pair of true wireless open-ear earbuds that sit on ear hooks instead of in the ear canal, so ambient sound stays audible. Each earbud weighs 7.8 g, and the hooks use a titanium-alloy construction rated for 7,000 bends. A three-point support system keeps them in place during exercise, and the earbuds are rated IPX7 against water and sweat.
Sound comes from 14.2mm wool composite drivers with directional acoustics, which aim sound toward the ear to reduce leakage. BassSurge bass enhancement uses real-time signal analysis and DSP processing, and spatial audio with head tracking is included. Four microphones with AI processing and wind noise reduction handle calls.
The earbuds connect over Bluetooth 5.3 with LDAC and SBC codecs, support Google Fast Pair and can stay connected to two devices at once. A low-latency game mode is available, and the EarFun Audio app for iOS and Android covers EQ, touch controls and battery checks. The charging case charges over USB-C or wirelessly. Battery life is up to 11 hours per charge and 42 hours with the case, with LDAC off.
