Rulefiss Q38 Bluetooth 5.3 Earbuds

The Rulefiss Q38 are true wireless in-ear headphones built for sport and daily listening. They use Bluetooth 5.3 for a stable link to phones, tablets and laptops. Active noise cancellation and CVC 8.0 dual-microphone processing target clearer calls and music. The purple finish and flexible earhooks aim to stay secure during movement.

48-hour case and IP7 waterproofing

An 800 mAh charging case provides up to 48 hours of total play time and recharges via USB-C. IP7-rated shells protect the internals from sweat and heavy rain during workouts. Three sizes of silicone tips are included to help seal the ear canal. Each bud can be used alone in mono mode or paired for stereo, though only one device connection is supported at a time.

14.2 mm drivers and 108 dB sensitivity

A 14.2 mm dynamic driver per earbud delivers a quoted response of 5 Hz to 20 kHz at 24 ohms impedance. High 108 dB sensitivity means loud volume is reachable with little power draw. AAC and SBC codecs handle the wireless audio stream. The design favours sustained output for long sessions rather than short peak bursts.
