Pro4 Bluetooth Headset with 5.0 Connectivity, 3-4 Hour Battery, and Binaural Call Clarity

This Pro4 Bluetooth headset provides a wireless audio solution centred on clear communication and stable connection. It employs Bluetooth 5.0 technology, specifically the jl6936d5.0 version, to link with smartphones, tablets, or computers without cables. The headset is designed for calls and media playback, offering high-definition binaural sound so both ears receive clear audio during conversations. Its operational range is practical for indoor use, allowing movement within 10 to 20 metres of the source device. The product arrives in packaging measuring 12 cm in length, 10 cm in width, and 3.5 cm in height, containing the core components needed for immediate use.
Features and Construction

The Pro4 headset’s performance is built on several specific technical components. Its design prioritises call clarity and efficient power use, supported by a dedicated chipset and battery system.
Material and Build
The audio driver uses a composite membrane copper ring speaker. This construction is focused on sound reproduction for both music and voice calls. The electrical components are powered by pure cobalt batteries; the earpiece contains a 30 mA cell, while the charging case holds a larger 260 mA pure cobalt battery with an integrated circuit (IC) protection board to manage charging safely.
Size and Practical Fit
The entire product set is contained within a compact package measuring 12 by 10 by 3.5 cm. This size indicates a portable system that includes two separate earpieces and a charging case. The earpieces are designed for binaural wear, fitting into both ears to deliver stereo sound and hands-free calling capability. The colour options are straightforward, limited to a classic black or white finish.
Uses and Placement

This headset suits scenarios where wireless audio and clear communication are needed without being tethered to a device. Its 10-20 metre range provides flexibility in various environments.
Event or Professional Use
For professional or on-the-move use, such as during presentations, warehouse work, or while commuting, the hands-free design and call clarity allow for multitasking. The 3-4 hours of working time covers typical shorter shifts or travel periods before requiring a return to the charging case. The true stereo chip supports clear audio for both listening to instructions and participating in conference calls.
Everyday Home Use
Around the home or office, the wireless range permits moving between rooms while staying connected to a phone call or audio stream. The high-definition binaural call feature makes it suitable for longer conversations with family or colleagues. The simple pairing via Bluetooth 5.0 facilitates quick connection to everyday devices like laptops or televisions for private listening.
Benefits and Buying Value

The value of this headset lies in its specific technical specifications that address core needs for wireless audio and calling, without superfluous features.
Reuse and Low Maintenance
The product is designed for repeated daily use. The charging case extends utility by offering a 30-day standby time, meaning the case itself holds charge for a month to top up the earpieces as needed. This system reduces the frequency of finding a power outlet for the main case. The inclusion of a charging cable and manual provides the essentials for ongoing use.
Why Choose This Product
This headset provides a defined set of features: Bluetooth 5.0 for a modern stable connection, a stated 3-4 hour working time for predictability, and binaural call clarity for communication. It offers a complete ready-to-use kit with two earpieces, a charging case, and necessary accessories. For users seeking a wireless headset focused on these practical, measurable functions within a black or white colour scheme, this product presents a clear, specification-backed option.
