The ACEFAST W1 are everyday Bluetooth 5.4 true wireless earbuds that blend powerful 13 mm drivers with active noise cancelling (up to ~35 dB) for immersive listening. A 4-mic ENC array helps voices stay clear on calls, while Transparency mode lets outside sound in when needed. You get about 8 hours per charge (~35 hours total with the 400 mAh case), and the case’s LED digital display shows battery at a glance. Built for daily use with IPX4 splash resistance and USB-C charging, W1 is a practical pick for commuters, students and office users in Bangladesh—compatible with both Android and iPhone.
