OWS Pro headphones provide epic sound and an incredibly comfortable experience. Compared with traditional in-ear earbuds, the OWS Pro uses an innovative ear-hanging design and has been rigorously tested to calculate the most accurate ear fulcrum to achieve a stable and firm position. Oladances unique battery behind design provides better balance for sports than normal open earphones, without applying pressure. Equipped with dual 23mm*10mm dynamic drivers plus a primary chip and an amplifier chip, the OWS Pro earphones can deliver rich, full-range sound while minimizing sound that others can hear, all without requiring a tight fit. Far beyond traditional headphones' soundscape. Each earpiece has 16 hours of play time, and a physical power button to help preserve battery life without the case. The OWS Pro charging case provides another 58 hours of battery life, and just 15 minutes of charging can add 6 hours of play time. Focus Mode reduces distracting environmental noises, and the clarity of your calls is preserved by wind noise reduction technology. Whether you are working or relaxing, indoors or outdoors, OWS Pro will deliver exceptional sound, battery life, and comfort all day.
