Rulefiss 75H Wireless earbuds with ANC and 75h battery
Product description
This lightweight sports earbud set combines secure earhooks with extended battery life and IP7 water resistance for gym sessions, running and everyday use. With Bluetooth 5.4 and up to 75 hours total playtime according to the manufacturer, these Rulefiss earphones aim to keep workouts on track while delivering clear calls and punchy stereo sound.
Key Points
The design uses soft silicone earhooks and three sizes of ear tips to improve fit during high‑movement activities, while each bud weighs about 4.3 g for low‑fatigue wear. Bluetooth 5.4 promises faster data transmission and improved connection stability compared with earlier versions, and the earbuds reconnect automatically after the first pairing when removed from the charging case. The charging case includes a dual LED display showing case battery level and individual earbud charge status.

Benefits
Sound is geared towards active use with a separate sound chamber and large drivers that aim to deliver a lively stereo presentation during workouts. The multi‑microphone arrangement and CVC noise reduction help improve call clarity in noisy environments, which is useful when taking calls on the move. Battery performance reduces the need for frequent recharging on short trips or long training days.
Usage Recommendations
For running and gym use, select the ear tips that provide the most secure seal and tuck the soft earhook over the ear for extra stability. The touch controls permit music playback, volume adjustments and call handling without reaching for your phone, although it helps to familiarise yourself with the tap patterns before heavy exercise. Consider wiping the metal contacts dry after sweaty sessions to help prevent corrosion, as advised by the manufacturer.
