ACEFAST N4 Wireless Neckband

The ACEFAST N4 Wireless Neckband is designed for users who want powerful everyday audio, an extremely long battery life, and convenient wireless connectivity. Featuring Bluetooth 5.3, 10mm dynamic drivers, an 800mAh battery, TF card playback, an LED digital display, and USB Type-C fast charging, the N4 is an excellent choice for music, calls, travel, workouts, commuting, and extended daily use.

Powerful Sound with 10mm Dynamic Drivers

The ACEFAST N4 features 10mm dynamic drivers designed to deliver clear and enjoyable sound. With a 20Hz–20kHz frequency response, the neckband provides a wide audio range for music, podcasts, videos, and phone calls.

The in-ear design helps provide a secure fit and allows you to enjoy your content comfortably during everyday activities.

Bluetooth 5.3 Connectivity

With Bluetooth 5.3, the ACEFAST N4 provides a stable wireless connection with compatible smartphones, tablets, laptops, and other Bluetooth-enabled devices. It supports a transmission distance of up to 10 meters, giving you convenient freedom of movement.

Massive 800mAh Battery

One of the biggest highlights of the ACEFAST N4 is its 800mAh battery. It can provide up to 130 hours of music playback at 60% volume, up to 100 hours of talk time, and 300 hours or more of standby time.

This makes the N4 particularly useful for long journeys, office work, travel, commuting, and users who do not want to charge their earphones frequently.

USB Type-C Fast Charging

The ACEFAST N4 uses a convenient USB Type-C charging port. A full charge takes approximately 3 hours, while its fast-charging feature can provide up to 10 hours of playback from just 10 minutes of charging.

This makes it easy to quickly recharge the neckband when you are in a hurry.

TF Card Playback

The ACEFAST N4 supports TF card playback, allowing you to listen to compatible music files directly from a memory card without connecting the neckband to a smartphone.

This feature is especially useful for travel, exercise, or situations where you want to listen to music without using your phone.

LED Digital Display

The built-in LED digital display provides convenient information about the device’s battery level and volume, allowing you to check important status information at a glance.

Comfortable Neckband Design

The ACEFAST N4 features a skin-friendly silicone ergonomic neckband designed for comfortable extended use. Its flexible neckband sits around your neck while the in-ear earbuds provide a secure fit.

The earbuds also feature a magnetic absorption design, allowing them to attach together when not in use and helping keep the earphones organized.

IPX4 Water Resistance

With an IPX4 water-resistance rating, the ACEFAST N4 can handle sweat and light splashes. This makes it suitable for walking, commuting, workouts, and normal outdoor use.

However, IPX4 does not mean the neckband is fully waterproof, so it should not be submerged in water.

Built-in Microphone for Calls

The ACEFAST N4 includes a built-in microphone for hands-free phone calls. Combined with its long battery life and comfortable neckband design, it is suitable for both entertainment and everyday communication.
