The audio will automatically switch between the two. In my tests, there was a short, 2-3 second delay between the time I paused the audio on my mobile phone and when the audio on my computer was directed to the headset. Though noticeable, this delay wasn’t a big deal. How about that Microphone? Our Voyager 4320 UC came in one, along with a tiny USB-A BT700 Bluetooth adapter and a USB-A to USB-C cable. The cable is required to charge the headphones, but it can also double to provide a wired link to a computer should you not wish to use Bluetooth. The positioning of the Voyager 4320 UC between these products hints that Poly is looking to draw customers from both ends of this spectrum. 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. I created a Youtube video where I do an overview, sound, and range test. Countless people prefer to watch video for their content consumption rather than having to read it. If you’re one of those people, I’ve got just the video for you.
In our test the audio began to fail near the 80 foot mark. What can you expect to receive? I’d say somewhere in the 80 range. This could vary somewhat by the number and type of obstructions between the headset and the device it’s connected to. The more obstacles, the weaker the signal. The weaker the signal, the less wireless range.
In both cases, the Poly Voyager 4320 performed great. Whether office noise or a full on blender, you could still hear my voice loud and clear with little to no evidence of noise going on around me. Where we did experience a little discomfort is that the sideways pressure applied by the band trapped the reviewers' glasses between his ear and skull. Those with less beach-ball inspired craniums will probably be fine, but for others, these might prove unsuitable for prolonged use. Whether you’re working in a business setting, or traveling with a mix of business and personal use, the Poly Voyager 4320 battery will provide you with plenty of juice to get the job done. What can I expect to receive for wireless talk range? You can also use the 4320 as a wired headset when charging. In other words, if you use the included USB-C to USB-A cable, and plug it into the headset and computer, you can use it as you’d use a wired USB headset.
You can also connect the Poly Voyager 4320 to a mobile device via Bluetooth. The 4320 uses the latest version of Bluetooth which is version 5.2. While connected to a mobile device, you can simultaneously be connected to a computer. The microphone is part of a noise-cancelling boom with dual microphone acoustic fence technology. That should reduce any environmental sounds propagating to be heard by the other end of a call or conference. However, there is no active noise cancellation in the headphones, so the operator will still hear those sounds. This is an impressive wireless headset especially for the price. It’s considered to be a budget friendly product, and to that end, Poly hit the mark. 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.Alongside the hardware configuration functions, Poly Lens Desktop App also has wellness reminders to tell users when they need to move around or look away from the screen. The Poly Voyager 4320 connects to a computer via USB. It comes with a USB dongle, sometimes referred to as an adapter. Specifically, this is the new and improved Poly BT700 that replaced the previous BT600 model.
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.
Networking
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. Being able to use the headset as a wired version while charging is a nice benefit too. I look at that as frosting on the cake. Having this capability is more than another feature Poly can put on their datasheet. Instead, it’s a really useful feature that can help you to complete a call if your battery decides to give out in the middle of your call. The audio representation to the wearer isn’t spectacular, but it is better than it needs to be for the typical usage.
