If you can wear them all day, the experience is a good one, with very clear and balanced audio and excellent battery life. There are headsets that offer even longer battery lives, but the ability to fast charge these enough for more than a working day of use in just 15 minutes is handy. Even without active noise cancellation, the Voyager 4320 UC provide clear sound and excellent clarity for anyone at the recipient end of the conversation. Whenever something significant happens, like the headset powers on or connects to the Bluetooth adapters, a voice informs the wearer what has occurred. From a user perspective, these are very friendly and easy to use. The one can is a single USB-C port that can be used for wired use and to charge the unit, and on either side of this are two small recesses designed to help engage the connections on the optional charging stand. The American giant Poly adapts to the global professional evolution and user needs by introducing a new range of products: Voyager 4300. Designed for professionals who want the freedom and mobility to communicate, the Voyager 4300 Series wireless headsets are comfortable, discreet and, above all, flexible solutions that respond to the new global professional approach: hybrid working. By choosing a Voyager 4300 Series headset, professionals can talk hands-free wherever they are - in the office, at home or even on the move - without losing efficiency. Voyager 4300 Series headsets can be used for both professional and personal use to play media through their Bluetooth connection. For professionals

The Voyager 4320 USB-A is a stereo headset designed for professionals who want superior sound insulation for their conversations, so they can fully immerse themselves in the conversation in question. This device will offer you great convenience during your exchanges. It features two low-pressure faux leather headphones, a memory foam headband and a flexible boom, all adjustable to your liking. The dual USB-A + Bluetooth connection of the headset allows you to use it on multiple devices such as: PC/Mac via the included dongle, smartphone or tablet via simple Bluetooth pairing. As a multipoint solution, the Voyager 4320 USB-A can be used on two devices simultaneously, allowing you to juggle multiple devices on a day-to-day basis. Powerful battery life: 24 hours of talk time Adjustment for head size is via notched arms that slide inside the headband. Once you’ve set these to your optimal position, there is sufficient friction that they should move while you are handling the headset away from your head. Voyager Focus 2 UC connects to PC/Mac via new BT700 USB-A or USB-C adapter and a mobile phone via Bluetooth 5.1; Voyager Focus 2 with Voyager Office base (accessory, sold separately) connects to a desk phone (via telephone interface cable), computer (via USB-A cable) and mobile (via Bluetooth). These are remarkably straightforward to use, as Ploy avoided any complicated buttons or controls to confuse the user. Up to 50 m/164 ft (UC version) – increased range due to new BT700 USB adapter; up to 91 m/300 ft (Office version)mAh lithium-ion battery: 24 hours talk time, 47 hours listening time and up to 50 days standby time Handling these for the first time, they feel lightweight (162g) but substantial. Construction appears to be primarily glass-reinforced plastic with very high-quality injection moulding used throughout. Talk time: Up to 24 hours (online indicator Off – requires setting change via Poly Lens/Plantronics Hub)

While this makes the construction of the monoaural models very straightforward, it could also makes these a less compelling solution for those that are left-handed. All the volume controls and the microphone boom are on the right. If the 4300 series has a stand-out feature, it’s undoubtedly the battery management, enabling up to 24 hours of talk-time and up to 47 hours of listening. It takes just 1.6 hours (96 minutes) to recharge fully, and you can get sufficient battery power for 10 hours from just 15 minutes of power connection. On the same side are three widely spaced buttons for increasing and decreasing volume and ending or starting a call on the end of the can. Lights around those show the call status of the headset wearer to those nearby, a feature we’d associate more with call centre applications. Even if they weren’t entirely comfortable for our reviewer, for the majority of normal humans, these should be fine with these. As with all headphones, their suitability for all-day wear is a personal thing, and we wouldn't assume to say that everyone would find them comfortable enough for extended use.greater noise reduction compared to Voyager Focus with Acoustic Fence technology to Microsoft Teams Open Office Premium level Voyager 4300 UC Series connects to PC/Mac via new BT700 USB-A or USB-C adapter and a mobile phone via Bluetooth 5.1; Voyager 4300 with Voyager Office base (accessory) connects to a desk phone (via telephone interface cable), computer (via USB-A cable) and mobile (via Bluetooth) with the Office base. It is also obvious that the designer of these conceived them as both stereo and monoaural from the outset, as almost everything necessary is on the right side of the headset. No controls are on the left, reducing that side to merely a left-side driver.
