The ACEFAST H5 are everyday over-ear Bluetooth headphones with active noise cancelling (up to ~30 dB) to reduce distractions on commutes, in class, or at the office. Large 40 mm drivers deliver clear, full sound with SBC/AAC support, while Bluetooth 5.4 keeps connections stable up to 10 meters. A robust 500 mAh battery powers up to ~65 hours of playback with ANC off (~45 hours with ANC on), and the USB-C (5V/1A) port recharges the headset in about 2.5 hours. A foldable design makes it easy to carry—ideal for Android, iPhone and PC users who want long battery life with effective noise reduction.
