Bluetooth 5.3 Wireless Earbuds with Immersive HiFi Stereo

From the brand Rulefiss, a smart device brand founded in 2018, we offer a wide range of products including smartwatches, Bluetooth earbuds, and Bluetooth speakers. We combine fashion and innovative technology to turn smart devices into carriers of personal style, with a customer-centric approach and a focus on providing high-quality after-sales service.

Rulefiss' wireless earphones weigh only 8 grams and feature a 3D bionic ergonomic design that fits perfectly in the ear canal, ensuring a comfortable and light experience. The earphones are also IP7 waterproof, efficiently protecting them from damage caused by sweat and rain, making them ideal for exercise and sports.

Each Bluetooth headphone can be used alone or shared with friends, offering a monaural or binaural mode. The Bluetooth 5.3 chip and high-sensitivity FPC antenna ensure quick and stable connections within 15 meters, with lower latency and lower power consumption. The headphones support Bluetooth protocols such as HSP, HFP, A2DP, and AVRCP, and automatically connect when taken out of the charging case.

The Rulefiss New Q38 wireless earbuds use a 13mm graphene moving coil unit, with an increased frequency bandwidth of 45%. This results in well-detailed instruments, full mids, and punchier high-pitch (20Hz-20kHz) with excellent dynamic range and accuracy. The earbuds also have built-in 2 clear microphones and CVC 8.0 technology, retaining 85% of the sound for clearer calls.

The wireless earphones' charging case features a dual LED display that shows the remaining power in percentage, allowing you to monitor the status of your headphones and case. The 800mAh compact charging case provides up to 48 hours of playtime, and with Type-C quick charge, it takes only 1.5 hours to fully charge.

The Q38 sport wireless headphones are designed with a soft, ultra-light, and flexible 45° earhook structure, providing a comfortable fit for your ears. With three different sizes of high-quality silicone earplugs (S/M/L) and IP7 certified waterproof technology, the earbuds can withstand sweat and rain during sports or daily use, making them the best choice for workouts, running, and the gym.

The multi-function touch panel on each earbud allows you to conveniently play, pause, adjust volume, answer and end calls, and activate Siri or Google Assistant. The Bluetooth earphones are compatible with smartphones, tablets, and laptops using iOS 9.0/Android 5.0 or later, ensuring a tangle-free, convenient experience.
