Bluetooth 5.3 HiFi Stereo Wireless Earbuds with ENC Mic, Waterproof, Sports Earhooks

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.

The wireless earphones from Rulefiss weigh only 8 g and have a 3D bionic ergonomic design that fits perfectly in the ear canal, providing a comfortable and lightweight experience. They are also IP7 waterproof, efficiently protecting the sports headphones from damage caused by sweat and rain to ensure their lifespan, making them ideal for exercise and sports.

Each Bluetooth headphone can be used alone and shared with friends at any time, or used simultaneously for powerful stereo sound. 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. They support Bluetooth protocols such as HSP, HFP, A2DP, and AVRCP, and will automatically connect when taken out of the charging case after the initial pairing.

The Rulefiss New Q38 wireless earbuds use AAC/SBC audio decoders and a 13mm graphene moving coil unit, with a frequency bandwidth increased by 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 and making calls clearer.

The wireless earphones come with an over-ear charging case with an LED power display that shows the remaining power in percentage. The case provides up to 48 hours of playtime, with a single charge offering 6-8 hours of normal usage. The case can be quickly charged in 1.5 hours using a Type-C quick charge.

The sport wireless headphones are designed with a soft, ultra-light, and flexible 45° earhook structure that fits the 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. They are a great choice for workouts, running, and the gym.

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