Bluetooth 5.3 Wireless Earbuds with HiFi Stereo, 48Hrs Playtime, IP7 Waterproof

From the brand Rulefiss, Rulefiss is a smart device brand founded in 2018 that offers a wide range of products including smartwatches, Bluetooth earbuds, and Bluetooth smart devices such as Bluetooth speakers. The company combines fashion and innovative technology to turn smart devices into carriers of personal style.

Rulefiss' customer-centric approach provides high-quality after-sales service. The wireless earphones from Rulefiss weigh only 8g, have a 3D bionic ergonomic design, and fit perfectly in the ear canal. The IP7 waterproof technology efficiently protects the sports headphones from damage caused by sweat and rain, making them ideal for exercise and sports.

The Rulefiss Bluetooth earphones can be used in either monaural or binaural mode. Each headphone can be used alone and shared with friends at any time, or two headphones can be used simultaneously for powerful stereo sound (although they cannot connect to two devices at the same time).

The Bluetooth 5.3 chip and high-sensitivity FPC antenna ensure that the headphones connect quickly and stably within 15 meters, with lower latency and lower power consumption. The headphones support Bluetooth protocols such as HSP, HFP, A2DP, and AVRCP, and they automatically connect when taken out of the charging case after the initial pairing.

The Rulefiss New Q38 wireless earbuds use a 13mm graphene moving coil unit, which increases the frequency bandwidth by 45%. This provides 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 come with an 800mAh compact charging case that provides up to 48 hours of playtime. The case has a dual LED display that shows the remaining power in percentage, and it can be quickly charged using a Type-C quick charge, taking only 1.5 hours to fully charge.

The Q38 sport wireless headphones are designed with a soft, ultra-light, and flexible 45° earhook structure, which can fit your ears smoothly. They come with 3 different sizes of high-quality silicone earplugs (S/M/L) and are IP7 certified waterproof, protecting them from sweat and rain during sports or daily use.

The earphones also feature a multi-function touch panel on each earbud, allowing for convenient control of play, pause, volume, call management, and voice assistant activation. They are compatible with smartphones, tablets, and laptops running iOS 9.0/Android 5.0 or later, providing a tangle-free and convenient listening experience.
