HainoTeko OWS-H4 Open-Fit SportBuds — Bluetooth 5.4 Earphones with Touch Controls, ENC Call Noise Reduction & 30 hr Battery (White)

Meet the HainoTeko OWS-H4—wireless earphones that keep you aware of your surroundings without sacrificing immersive sound. An open-fit design rests lightly outside the ear canal, while custom 16 mm drivers pump out deep bass, clear mids, and sparkling highs. Bluetooth 5.4 pairs in seconds and holds a steady link up to 10 meters. Tap-sensitive housings let you adjust volume, skip tracks, answer calls, or summon your voice assistant without reaching for your phone. Software-based ENC filters background chatter so your voice stays crisp on calls. Each bud plays for up to 6.5 hours, and the 500 mAh charging case stretches total listening time to an impressive 30 hours—enough for a full week of commutes or a weekend adventure. Lightweight silicone-and-ABS construction shrugs off sweat, making the OWS-H4 the perfect everyday companion from the gym to the office.
