The Acefast H4 ANC Wireless Headset is designed for immersive listening and all-day comfort, combining powerful hybrid active noise cancellation with professional Hi-Fi sound and extra-long battery life for travel, work, and entertainment.

Engineered with pro-grade 40mm dynamic moving coil speakers, it accurately presents high-resolution audio with rich mids, crisp highs, and deep bass.

The built-in high-definition microphone features integrated wind protection to deliver exceptionally clear vocal clarity during hands-free phone calls and online meetings.

Soft over-ear cushions crafted from premium skin-friendly protein leather and zero-pressure memory foam provide breathable, long-lasting comfort, while the lightweight adjustable headband and rotating foldable earcups ensure a secure, custom fit that packs away easily into any travel bag.

Powered by an upgraded Bluetooth V5.3 chip, the headset delivers ultra-stable, low-latency wireless connectivity with a transmission range of up to 10 metres, making it ideal for use with smartphones, tablets, and laptops.

For added versatility, the headset includes an integrated 3.5mm AUX port and a detachable audio cable, allowing you to switch instantly to a wired connection when the battery runs low or when connecting to non-Bluetooth devices.

An internal 500mAh lithium-ion battery provides up to 55 hours of continuous music playback on a single charge, supported by convenient USB-C fast charging that reduces downtime between listening sessions.

Rated IPX4 water resistant, the durable construction is protected against sweat and light splashes, making it an ideal companion for outdoor commutes, daily workouts, remote work, and multimedia entertainment.
