Pro4 True Stereo Wireless Earbuds with Bluetooth 5.0 and 30-Day Standby Charging Case

The Pro4 wireless earbuds offer a cable-free audio solution built around core specifications for reliable performance. Centred on a Bluetooth 5.0 chipset, they provide a stable connection suitable for both music listening and clear, binaural phone calls. Their practical design includes a compact charging case that significantly extends usability, offering up to 30 days of standby power. Available in classic black or white, these earbuds are constructed with specific audio components aimed at delivering a stereo listening experience directly from your smartphone, tablet, or laptop without the hassle of wires.

Features and Construction

The Pro4 earbuds are defined by several key technical specifications that determine their performance. The build focuses on wireless connectivity, audio quality, and battery management to serve as a practical personal audio accessory for daily use.

Material and Build

The core audio component is a high-quality composite membrane copper ring speaker. This speaker construction is paired with a dedicated true stereo chip, which processes the audio signal to deliver distinct left and right channel separation. The earbuds and their charging case are powered by pure cobalt battery cells, a stated material choice for the power source. The charging case battery includes an integrated circuit (IC) protection board as part of its build, which helps manage charging cycles and battery safety.

Size and Practical Fit

The most clearly defined dimension is for the charging case, which measures 12 cm in length, 10 cm in width, and 3.5 cm in depth. This compact size makes it easy to carry in a pocket or bag. The earbuds themselves are designed for a wireless, in-ear fit, though their exact dimensions and weight are not specified in the provided source material. The available colour options are black and white, providing a choice between two neutral, versatile finishes.

Uses and Placement

With their specified features, the Pro4 earbuds fit into a range of common audio scenarios. Their wireless nature and call functionality make them suitable for both leisure and communication needs in various environments.

Event or Professional Use

Their stable Bluetooth 5.0 connection and 10-20 metre wireless range allow for movement during tasks. The high-definition binaural call capability makes them applicable for clear hands-free communication in settings like remote work calls, video conferences, or while managing other activities. The 3-4 hours of continuous working time per charge is sufficient for most meetings or extended work sessions without requiring a mid-session recharge from the case.

Everyday Home Use

For personal entertainment, the true stereo chip and composite membrane speaker aim to provide an improved listening experience over mono Bluetooth speakers for music, podcasts, and audio from videos. The long 30-day standby time of the charging case means the earbuds are likely to retain charge even if not used for several days, making them ready for spontaneous use around the home, during commutes, or while exercising without frequent cable charging.

Benefits and Buying Value

The value of the Pro4 earbuds stems from the combination of their stated wireless performance, audio setup, and battery system. This package addresses the core needs of users looking to replace wired earphones with a specific set of reliable wireless features.

Reuse and Low Maintenance

The product is designed for repeated daily use. The earbuds recharge within their case, and the case itself can be recharged via the included cable. The IC protection board on the case's battery is a stated feature intended to support the battery's lifecycle. Maintenance primarily involves keeping the earbuds and charging contacts clean and following the basic charging guidance in the manual.

Why Choose This Product

If your priority is a wireless audio accessory with clear call functionality and true stereo sound, the Pro4 earbuds offer these specific features. The extended standby time provided by the charging case is a practical advantage for users who do not wish to charge their accessories daily. The combination of Bluetooth 5.0 for connection stability, the dedicated audio components for sound, and the straightforward black or white colour choice presents a focused alternative to wired headphones.
