Pro4 Bluetooth Wireless Earbuds with True Stereo Chip and 3-4 Hour Battery Life

The Pro4 Bluetooth headset offers a complete wireless audio solution for daily communication and entertainment needs. These earbuds utilise Bluetooth 5.0 technology to provide stable connectivity within a 10-20 metre range, allowing freedom of movement while maintaining clear audio transmission. With binaural high-definition calling capabilities and a true stereo chip, the Pro4 delivers balanced sound to both ears, whether you're taking calls or listening to music. The compact charging case extends usability with its 260 mA pure cobalt battery, providing up to 30 days of standby time when the earbuds are stored and not in active use.

Features and Construction

The Pro4 Bluetooth headset combines several practical features in a portable design, focusing on reliable performance and user convenience through its technical specifications.

Material and Build

Each earbud incorporates a high-quality composite membrane copper ring speaker, which converts electrical signals into audible sound. The composite membrane construction aims to deliver clear audio across different frequencies. The charging case contains a 260 mA pure cobalt battery protected by an IC protection board, designed to manage charging cycles and help maintain battery health over time. Both earbuds themselves house smaller 30 mA pure cobalt batteries to power their operation during use.

Size and Practical Fit

The complete product package measures 12×10×3.5 cm, making it compact enough for easy storage in bags or pockets. The earbuds' wireless design eliminates cable clutter, and their inclusion of a charging case provides organised storage while replenishing power. Available in both black and white colour options, the Pro4 can match different personal styles or equipment colours without requiring additional accessories or modifications.

Uses and Placement

With its balance of calling clarity and music playback capabilities, the Pro4 Bluetooth headset serves multiple roles in both professional and personal environments where hands-free audio is beneficial.

Event or Professional Use

The 10-20 metre Bluetooth transmission range allows users to move freely within meeting rooms, exhibition spaces, or small offices while maintaining connection to their audio source. Binaural high-definition calling ensures both ears receive clear voice transmission during conference calls or client conversations. The true stereo chip supports balanced audio distribution, which can help with spatial awareness during presentations or when monitoring multiple audio channels in educational or training scenarios.

Everyday Home Use

For personal entertainment, the Pro4's 3-4 hours of working time per charge covers typical commuting periods, workout sessions, or extended listening periods at home. The charging case's 30-day standby time means the earbuds remain ready for use even after days or weeks of inactivity. Wireless operation simplifies activities like cooking, cleaning, or exercising where cables might interfere with movement, and the compact size makes them easy to carry during travel or daily routines.

Benefits and Buying Value

The Pro4 Bluetooth headset provides practical advantages through its complete kit approach and straightforward functionality, offering a self-contained audio solution without requiring additional purchases.

Reuse and Low Maintenance

The included charging case serves both as protective storage and a power bank, reducing wear on the earbuds' ports through magnetic or contact-based charging. With two earbuds provided, users have a complete stereo set from the outset. The IC protection board in the charging case aims to manage charging cycles appropriately, which may help maintain battery performance over repeated charging sessions without requiring user intervention or technical knowledge.

Why Choose This Product

This Bluetooth headset offers a balanced combination of working time, transmission range, and audio quality within its specified parameters. The true stereo chip differentiates it from mono Bluetooth earpieces by providing separate audio channels to each ear. With all necessary components included—earbuds, charging case, cable, and documentation—the Pro4 provides a ready-to-use solution immediately upon unboxing. The choice between black and white colour options allows some personalisation without affecting the core technical specifications or performance.
