It uses a true stereo chip and a 14mm composite membrane copper ring speaker to separate audio channels, making voices sound distinct and reducing the muddiness common in mono headsets. With Bluetooth 5.0, it maintains a stable connection for up to 20 metres, letting you move freely during calls. The headset itself offers 3 to 4 hours of continuous use, while its compact charging case—with a 260 mA battery—provides multiple full recharges and keeps the earpieces protected. Available in classic black or white, it's a practical solution for professionals, commuters, and anyone needing hands-free convenience without compromising on call clarity.\n\n\u003ch2\u003eFeatures and Build Quality of the Pro4 Headset\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black Pro4 true wireless Bluetooth earbuds and charging case on a white background.\" 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 and construction that contribute to the Pro4's performance, from its audio driver to its power management system.\n\n\u003ch3\u003eAudio Driver and Chip Design\u003c\/h3\u003e\nThe core of the Pro4's sound is its high-quality composite membrane copper ring speaker. The composite polymer diaphragm is responsive to mid-range frequencies critical for voice, while the copper voice coil ensures accurate movement. This 14mm driver is powered by a true stereo chip, which processes left and right audio channels independently. This separation prevents the audio from collapsing into a single, compressed signal, a common issue with cheaper mono Bluetooth headsets. The result is call audio where you can better distinguish between multiple speakers or hear subtle nuances in tone.\n\n\u003ch3\u003eWireless Connectivity and Battery Performance\u003c\/h3\u003e\nConnection stability is managed by the Bluetooth 5.0 protocol, which offers improved data throughput and range over older versions. The specified barrier-free distance of 10 to 20 metres is achievable in open environments, reducing dropouts when your paired device is in another room. For power, each earpiece contains a 30 mA pure cobalt battery. This chemistry provides a consistent voltage output, which translates to the advertised 3 to 4 hours of working time at moderate volume. The charging case uses a larger 260 mA pure cobalt cell with an IC protection board, a circuit that automatically stops charging when the battery is full to prevent damage and prolong its overall service life.\n\n\u003ch3\u003eConstruction and Ergonomic Fit\u003c\/h3\u003ePractical Applications for the Pro4 Headset\nUnderstanding how this headset performs in real-world situations helps illustrate its value in both professional and personal contexts.\n\n\u003ch3\u003eProfessional and Remote Work Use\u003c\/h3\u003e\nFor remote workers or professionals in open-plan offices, the Pro4 headset addresses specific needs. The 4-hour battery life comfortably covers a half-day of meetings or calls without requiring a mid-day recharge. The true stereo audio makes conference calls easier to follow, especially when multiple participants are speaking. The 20-metre range allows you to step away from your desk to fetch a document or make a drink without disconnecting, maintaining privacy and continuity. The clear voice pickup minimises the need to repeat yourself, making virtual interactions more efficient.\n\n\u003ch3\u003eEveryday Commuting and Leisure Use\u003c\/h3\u003e\nFor the daily commute or leisure use, the Pro4 offers a hassle-free experience. The earpieces have a smooth, rounded finish that feels comfortable against the skin during extended wear, a direct result of the polished ABS plastic construction. The simple touch controls (implied by the chipset) allow you to manage calls and playback without fumbling for your phone. The charging case, at just 12 by 10 by 3.5 cm, slips easily into a jacket pocket or small bag, and its 30-day standby time means it's always ready to top up the earpieces, whether you're using them for podcasts on the Tube or taking a quick call while out shopping.\n\n\u003ch3\u003eVersatility and Style Combinations\u003c\/h3\u003eKey Benefits and Long-Term Value\nThe advantages of the Pro4 headset extend beyond its basic specifications, offering tangible value through its design and performance.\n\n\u003ch3\u003eCost-Effectiveness and Durability\u003c\/h3\u003e\nThe Pro4 presents a value proposition by combining features often found in more expensive models, like a true stereo chip and pure cobalt batteries, at an accessible price point. The use of ABS plastic for the housing provides impact resistance against accidental drops from ear height. The IC protection board in the charging case is a critical component for long-term value, as it actively prevents overcharging—a common cause of battery degradation. This attention to power management suggests the headset is built to maintain its battery performance over hundreds of charge cycles, reducing the likelihood of needing a replacement within a year or two.\n\n\u003ch3\u003eUser Experience and Satisfaction\u003c\/h3\u003eReasons to Choose the Pro4\nChoosing the Pro4 Bluetooth headset is a decision for those who prioritise clear communication and convenience. Its measurable benefits—4 hours of talk time, a 20-metre wireless range, and true stereo call audio—address specific shortcomings of basic wireless headsets. The inclusion of a high-capacity charging case with protective circuitry adds significant utility and safeguards your investment. If your daily routine involves multiple calls, commuting, or simply valuing clutter-free, reliable audio, the Pro4 provides a spec-focused solution that delivers on its core promises without unnecessary complexity or cost.\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black Pro4 true wireless Bluetooth earbuds and charging case on a white background.\" 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\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black Pro4 true wireless Bluetooth earbuds and charging case on a white background.\" 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=\"Black Pro4 true wireless Bluetooth earbuds and charging case on a white background.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/39\/2025-10-19\/original-image\/989039346685.webp\"\u003e\u003c\/div\u003e","brand":"dfewnq-9s","offers":[{"title":"Black","offer_id":53511307395409,"sku":"CJXFBXEJ01990-Black","price":36.98,"currency_code":"GBP","in_stock":true},{"title":"White","offer_id":53511307428177,"sku":"CJXFBXEJ01990-White","price":36.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1035\/0795\/1953\/files\/1639010845688.webp?v=1776059132","url":"https:\/\/celovian.com\/products\/pro4-bluetooth-headset-with-binaural-hd-call-clarity-and-up-to-4-hours-of-continuous-working-time-on-a-single-charge","provider":"Celovian","version":"1.0","type":"link"}
