This version (jl6936d5.0) maintains stable connections at distances up to 20 metres, even through walls and furniture, making it suitable for moving around offices or homes without losing connection. The high-definition binaural call system ensures both parties hear clear audio without the muffled quality common in budget headsets. With 3-4 hours of continuous use from each charge and a charging case that extends standby to 30 days, this headset supports extended use throughout the day without frequent recharging.\n\n\u003ch2\u003eTechnical Features and Audio Quality\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Pro4 Bluetooth wireless headset in charging case with earpieces, cable, and manual\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/39\/2025-10-19\/original-image\/1639010845688.webp\"\u003e\u003c\/div\u003e\nThis section details the specific components that deliver the Pro4's performance, from its transmission technology to its audio reproduction capabilities.\n\n\u003ch3\u003eBluetooth 5.0 Connectivity\u003c\/h3\u003e\nThe jl6936d5.0 Bluetooth chip provides the 10-20 metre transmission range that characterises the Pro4 headset. Unlike earlier Bluetooth versions that struggle beyond 10 metres, this implementation maintains connection stability through typical household barriers like walls and doors. The chip's power efficiency contributes to the 3-4 hour working time, as it consumes less battery during both active use and standby periods between calls.\n\n\u003ch3\u003eAudio Component Specifications\u003c\/h3\u003e\nEach earpiece contains a high-quality composite membrane copper ring speaker measuring approximately 10mm in diameter. This construction combines a flexible composite membrane for accurate high-frequency reproduction with a copper ring component that enhances mid-range vocal clarity. The true stereo chip processes left and right audio channels separately, creating proper spatial separation for music listening while maintaining vocal focus during calls.\n\n\u003ch3\u003eBattery and Power Management\u003c\/h3\u003e\nThe 30 mA pure cobalt batteries in each earpiece provide the 3-4 hour working time specification. Pure cobalt chemistry offers more consistent voltage output than standard lithium-ion cells, preventing audio distortion as batteries discharge. The charging case's 260 mA battery includes an IC protection board that monitors charging cycles, preventing overcharging that reduces battery lifespan. This system enables the 30-day standby time by maintaining optimal charge levels without constant power draw.\n\n\u003ch2\u003ePractical Applications and Usage Scenarios\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Pro4 Bluetooth wireless headset in charging case with earpieces, cable, and manual\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/39\/2025-10-19\/original-image\/22204771763486_c49f884f-492f-4683-ab62-e73df139cc3f.webp\"\u003e\u003c\/div\u003e\nThese specific situations demonstrate how the Pro4's technical specifications translate to real-world performance across different environments.\n\n\u003ch3\u003eProfessional Office Use\u003c\/h3\u003e\nIn office environments, the 20-metre range allows movement between desks, to printers, or during brief meetings without disconnecting from calls. The high-definition binaural call technology filters background office noise like keyboard typing or distant conversations, ensuring clear communication during conference calls. The 3-4 hour battery supports typical workday call schedules without midday charging, while the charging case provides backup power during extended sessions.\n\n\u003ch3\u003eEveryday Home and Commute Use\u003c\/h3\u003e\nAt home, the barrier-free transmission works through walls, enabling movement between rooms during calls. The composite membrane copper ring speakers deliver a balanced audio experience where voices sound natural rather than tinny or muffled. During commutes, the secure fit and stable Bluetooth connection prevent dropouts in areas with wireless interference, while the charging case's compact 12×10×3.5cm size fits easily in bags or pockets.\n\n\u003ch3\u003eVersatile Audio Applications\u003c\/h3\u003ePerformance Benefits and Value Considerations\nThese advantages highlight how the Pro4's specific features provide measurable benefits compared to alternative options.\n\n\u003ch3\u003eLong-Term Value and Durability\u003c\/h3\u003e\nThe pure cobalt batteries maintain capacity through approximately 500 charge cycles before significant degradation, compared to 300-400 cycles for standard lithium-ion cells in similar headsets. The IC protection board extends overall battery lifespan by preventing overcharging damage. At 3-4 hours per charge, this translates to 1500-2000 hours of use before battery replacement considerations, making the Pro4 suitable for daily users seeking long-term reliability.\n\n\u003ch3\u003eUser Experience and Satisfaction\u003c\/h3\u003ePurchase Decision Factors\u0026lt;\/h3\nChoosing the Pro4 headset provides specific advantages: the 20-metre range enables freedom of movement unavailable with 10-metre headsets, while the 3-4 hour battery supports longer usage between charges than many 2-3 hour alternatives. The charging case's 30-day standby ensures the headset remains charged during infrequent use, avoiding the frustration of dead batteries when needed unexpectedly. These measurable differences justify selection over basic Bluetooth headsets with shorter ranges and battery life.\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Pro4 Bluetooth wireless headset in charging case with earpieces, cable, and manual\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/39\/2025-10-19\/original-image\/717794684574.webp\"\u003e\u003c\/div\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Pro4 Bluetooth wireless headset in charging case with earpieces, cable, and manual\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/39\/2025-10-19\/original-image\/989039346685.webp\"\u003e\u003c\/div\u003e","brand":"t0zkis-0a","offers":[{"title":"Black","offer_id":56486684033355,"sku":"CJXFBXEJ01990-Black","price":36.98,"currency_code":"GBP","in_stock":true},{"title":"White","offer_id":56486684066123,"sku":"CJXFBXEJ01990-White","price":36.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/5778\/2347\/files\/1639010845688.webp?v=1770634990","url":"https:\/\/homeenjoy.us\/products\/pro4-bluetooth-headset-with-bluetooth-5-0-chip-for-high-definition-binaural-calls-offering-a-10-20-metre-barrier-free-transmission-distance-and-3-4-hours-of-continuous-working-time-per-charge","provider":"Homeenjoy.us","version":"1.0","type":"link"}
