Air conduction (open-ear) earbuds from the ACEFIT series, model FA005: the transducers rest in front of the ear canal instead of blocking it, leaving the ear open to the environment while delivering sound. The manufacturer announces an open “anti-noise” sound field and dynamic bass amplification, with an ear-hook design intended to stay in place without pressure. Connectivity is Bluetooth 5.4 (JL7016G8 chip) with SBC and AAC decoding, a frequency response of 20 Hz to 20 kHz and a range of at least 10 m. Published battery life reaches about 5 hours for the earbuds and 20 hours total with the charging case (400 mAh, USB-C 5V 0.4 A, full recharge in 2 hours); 10 minutes of charging gives about 1 hour of listening. Ultra-slim case, total weight 52 g, IPX4 water resistance, 18-month warranty.
