In Brief

Mid-range Plantronics USB headset with control panel for answer/ignore/end/hold (softphone dependant), volume and mute. Teams version includes a dedicated teams button. Also comes with a 3.5mm jack which then plugs into the control panel. NB USB-C connection is not compatible with mobile phones

Launch Date - August 2020

What We Love

+ Mid range USB headset
+ Wide, padded comfort headband for all day wearing
+ Plug and play simplicity -  no charging or pairing
+ Available in MS Teams or UC versions.  MS Teams version has a dedicated Teams button for instant access.
+ Comes with a case & leatherette ear cushions
+ Includes a 3.5mm jack which is great for the odd mobile call (most modern mobiles will need an adaptor to be compatible). That jack is also useful if you don't want to take your headset off every time you walk away from your desk - just unplug the jack and go!
+ Noise cancelling in the microphone (not earcups) to help block out your background noise for your caller.
+ Wear with the microphone on left or right (for mono versions you can have the earcup on either ear)
+ Flexible microphone boom
+ Depending on variant,  will connect to USB desk phones

What We Don't Love

- Corded headset, so you can't multi-task and have to stay at your desk 
- Adaptor required to make it work with most mobiles

In Detail

Launched in August 2020, this USB headset stands out as the budget-friendly option in the Plantronics/Poly lineup, featuring a versatile 3.5mm jack for connections to mobile phones or tablets, compatible with all brands, including Apple.

The 3305 series is fully compatible with Lync, Skype for Business, and Microsoft Teams, and naturally extends its functionality to all major softphones, as well as other programs like regular Skype, Dragon, and virtually any application you might want to use a headset for on your PC or laptop.

Equipped with a noise-canceling microphone, this headset ensures that background noise is effectively eliminated, delivering wideband audio for a natural and rich voice experience, making it feel as if you were there in person. Inbound audio quality is superb, and the Dynamic EQ feature intelligently adapts to music and multimedia, providing optimal sound for both calls and leisure.

Crafted for extended wear, the leatherette ear cushions and lightweight headband offer all-day comfort and a secure fit. It's crucial to note that this is not an active noise-canceling headset but rather a basic model with a plain adjustable headband. This version is designed to fold flat and includes a protective carry case for added convenience.

Control features encompass call functions such as answer/ignore/end/hold, redial, mute, and volume adjustment. All headsets in this series connect to Plantronics/Poly Manager Pro (available separately), making them ideal for large-scale deployments.

In summary, this is an excellent budget duo headset suitable for both mobile and standard USB use. With a stylish design and backed by a standard 2-year warranty, it offers a compelling combination of affordability and functionality.
