Core Technical Specifications

Understanding the technical foundation of this headset helps buyers appreciate its functional capabilities and limitations within real-world usage scenarios.

Wireless Connectivity Range

The Pro4 headset maintains a barrier-free transmission distance of 10 to 20 metres, allowing users to move freely while staying connected to their audio source. This range accommodates typical home or office environments where obstacles might occasionally interfere with signal strength. The jl6936d5.0 Bluetooth version ensures compatibility with most modern devices while maintaining stable connections during calls or media playback. Users should note that physical barriers such as walls may reduce the effective range, though the specified 10-20 metre capability represents optimal conditions.

Battery Performance Details

Each earphone contains a 30 mA pure cobalt battery providing 3 to 4 hours of continuous operation, suitable for commutes, work sessions, or exercise routines. The accompanying charging warehouse houses a 260 mA pure cobalt rechargeable battery equipped with an IC protection board, extending usability through multiple recharge cycles. This configuration delivers up to 30 days of standby time when earphones are stored in the case between uses, making it practical for intermittent users who may not charge daily.

Audio Component Construction

High-quality composite membrane copper ring speakers form the core audio delivery system, working in conjunction with the true stereo chip to produce balanced sound reproduction. This speaker design focuses on clarity for voice calls while maintaining adequate fidelity for music and media content. The binaural call feature utilises both earpieces to create a natural hearing experience during conversations, reducing listener fatigue during extended use periods.

Practical Usage Scenarios

Identifying appropriate use cases helps potential buyers determine if this headset matches their specific requirements and daily routines.

Professional Communication Needs

The high-definition binaural call capability makes this headset suitable for business calls, remote work meetings, or customer service applications where voice clarity matters. The 3-4 hour battery life supports half-day work sessions without requiring mid-day recharging, while the 10-20 metre range allows movement around a workspace without disconnecting. The true stereo chip ensures that conference calls maintain clear audio separation between participants.

Daily Commuting and Travel

Compact packaging dimensions of 12 by 10 by 3.5 centimetres make the complete set easy to carry in bags or pockets during travel. The 30-day standby time benefits occasional users who may not use their headset daily but need reliable performance when required. Available in black or white colour options, the design accommodates different aesthetic preferences while maintaining a professional appearance suitable for public transport or office environments.

Purchase Considerations

Evaluating the complete package contents and maintenance requirements ensures buyers understand exactly what they receive and how to maintain optimal performance.

Complete Package Contents

Each purchase includes two earphones, one charging bin, one charging cable, a user manual, packaging box, and certificate. This comprehensive set provides everything needed for immediate operation without requiring additional accessories. The inclusion of a certificate indicates compliance with relevant manufacturing standards, while the manual offers specific guidance for pairing and troubleshooting common connectivity issues.

Maintenance and Longevity

Regular charging cycles using the provided cable help maintain battery health in both the earpieces and charging case. Storing the earphones in the charging bin when not in use preserves battery life during the extended 30-day standby period. The pure cobalt battery technology offers consistent performance characteristics, though users should avoid extreme temperatures that could affect battery efficiency. The composite membrane speakers require no special maintenance beyond keeping them free from debris and moisture.
