Poly Voyager 4320 UC Review

Poly Voyager 4320 UC Review – Poly, formerly Polycom, a part of Plantronics, is an American multinational corporation that makes video, voice & content collaboration and communication technology. Polycom was co-founded in 1990 by Brian Hinman and Jeffrey Rodman. Plantronics bought Polycom in 2018 and they changed the name to Poly the following year. 

To say the pandemic has changed the way we live would be an understatement. It is now well-acknowledged that your physical presence at work is no longer correlated to your productivity. Ergo, working from home is the norm at present day. And, almost everyone needs to have a good pair of headphones for your ubiquitous virtual meetings.

Poly just recently released their latest Poly Voyager 4320 UC headset and we’re about to find out if it’s any good.

Is it easy to pair?

Yes, the pairing process is super simple. There are two ways to pair the headset. 

First is through the included Bluetooth adapter (BT700). Before plugging the adapter to your computer, you will need to download the Poly Lens desktop app. This app allows you to customise the headset according to your needs. 

Second is through the Bluetooth pairing to mobile devices. Just put your headset in pairing mode by sliding and holding the power button until you hear “pairing” and the headset will flash red and blue. And, make sure you turn on your Bluetooth to scan and pair the device. That’s it.

How’s the basic controls?

The controls are intuitive as they are pretty self-explanatory. 

There are a few buttons on the right side of the headset such as: 

  • Power on/off button
  • Adjust volume (up and down)
  • Call button (conveniently placed in the centre of the cup)

How’s the sound quality?

The sound quality is something that I really like from this headset, it’s crisp and clear. It almost resembles high-priced headphones, the lows and mids are perfectly balanced. I’ve been using it to listen to music and it’s been enjoyable. For virtual meetings, there is no complaint at all. The sound quality is sublime. It is that good. Plus, it’s quite comfortable for long usage too. It doesn’t feel too tight on my head at all. 

How’s the battery?

The battery life is great too. It has a 350 mAh Lithium-ion battery with talk time up to 24 hours (with online indicator off) or up to 18 hours (with online indicator on). 

To fully recharge it, it will take 1.6 hours. Alternatively, you can fast charge via USB-C port in just 15 minutes to get up to 10 hours listening time. And, standby time is up to 50 days.
