## Description

Stay connected with this USB-compatible headset featuring Poly's audio quality, flexible microphone, and comfortable, adjustable design for all-day use.

Review: Value for money product that works well - I regularly join meetings on zoom and had been told that others found it difficult to hear me when speaking whilst relying on the audio of my desktop computer. I was therefore advised to buy a headset with built in microphone. I therefore ordered this product as it suited my budget and used it for the first time this week. My colleagues were delighted as they said I could be clearly heard for the first time when I spoke and I found the quality of audio I received via the headphones to be good. The set is lightweight and comfortable to wear.
Review: Clear sound - Nice price nice fit.

### ⭐⭐⭐⭐⭐ Clear sound
*by S***Y on 8 January 2026*

Nice price nice fit.

### ⭐⭐⭐⭐⭐ Great headset
*by J***K on 25 September 2025*

Superb headset for the money, crisp sound and clear microphone for Teams calls and the controls work without issue. Haven't tried it for any other purpose but I think that wouldn't be fair, it's for calls and the voices sound more than adequate.
