The earbuds support various Bluetooth protocols, including HSP, HFP, A2DP, and AVRCP, ensuring a seamless listening experience.

One of the standout features of these earbuds is the impressive sound quality delivered by the 13mm drivers. With the AAC/SBC audio decoder and a graphene moving coil unit, the earbuds enhance frequency bandwidth by 45%. This results in well-detailed instruments, full mids, and punchy highs, covering a frequency range of 20Hz to 20kHz.

The compact 800mAh charging case boosts the playtime to an impressive 48 hours, making it perfect for long journeys or extended workouts. The earbuds themselves provide 6 to 8 hours of continuous playback on a single charge, ensuring you have the music you love at your fingertips.

Comfort is paramount in the design of these earbuds. The lightweight construction, where each earbud weighs only 7 grams, combined with the soft and flexible 45° earhook structure, ensures a snug and comfortable fit. With three different sizes of high-quality silicone earplugs (small, medium, and large) included, you can find the perfect fit for your ears.
