The ACEFAST H8 are comfortable over-ear Bluetooth headphones with active noise cancelling (up to ~30 dB) to reduce distractions on commutes, at the office or in class. Large 40 mm Hi-Fi drivers deliver clear, balanced sound, and Bluetooth 5.4 keeps your connection stable up to 10 meters. A robust 500 mAh battery powers up to ~60 hours of music (~40 hours with ANC) and recharges via USB-C (5V/1A) in about 2.5 hours. Thoughtful touches—stainless-steel adjustable headband, protein-leather cushions, rotatable cups, and an intuitive multifunction knob—make H8 a practical, long-battery headset for Android, iPhone and PC users in Bangladesh.
