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

The latest addition to the Rulefiss product line is the Q38 Sport Earbuds, a new upgrade in the brand's Bluetooth headphone offerings. These sports headphones feature Bluetooth 5.3 technology, providing a 150% increase in transmission speed and 50% improvement in stability compared to Bluetooth 5.2. With AAC/SBC audio decoding and a 14.2mm dynamic unit, the Q38 earbuds deliver detailed vocals, full mids, and deep bass for a high-quality listening experience.

Equipped with CVC 8.0 noise reduction technology and two microphones, the Q38 earbuds can retain 80% of the sound, ensuring clearer calls. They are also widely compatible with most Bluetooth-enabled phones, tablets, and laptops.

The box contents include a USB-C charging cable, a 48-hour charging case, two Q38 Bluetooth headsets, six soft silicone ear caps in various sizes (L/M/S), and a user manual in multiple languages.

The Q38 Sport Earbuds are designed with IP7 waterproof technology, effectively protecting them from damage caused by sweat and rain during exercise and sports activities. The headphones produce 3D HiFi stereo sound, with the AAC/SBC audio decoder and 14.2mm composite diaphragm increasing the audio frequency range by 45% (20Hz-20kHz). This results in layered instrumental details, clear vocals, resonant bass, and authentic highs for an immersive music experience.

Bluetooth 5.3 technology and dual-channel transmission provide a quick and stable connection, with a 100ms low latency that is compatible with iOS, Android, and Windows systems. The wireless earbuds automatically connect when removed from the charging case after the initial pairing.

The compact 800mAh charging case with LED power display allows for up to 6-8 hours of playtime on a single charge, with the case providing an additional 48 hours of playback. Using Type-C quick charge, the case can be fully recharged in just 1.5 hours.

The Q38 sport headphones feature a soft, ultra-light, and flexible 45-degree earhook structure, with each earbud weighing only 7g. Three different sizes of high-quality silicone earplugs (S/M/L) are included for a comfortable fit. The IP7 waterproof rating ensures protection from sweat and rain during workouts and daily use.

The Bluetooth earphones also offer smart touch control for convenient playback, volume adjustment, call management, and voice assistant activation. The sleek, glossy design with smooth lines and a comfortable touch completes the refined appearance of the Q38 Sport Earbuds.
