Logitech Stereo Headset H151. Speak clearly. Crisp calls with stereo sound make it easy to stay in touch. The noise-cancelling microphone reduces annoying background noise so you can be heard clearly. You can wear the microphone on your left or right, and rotate it up and out of your way when you're not using it. Personalise your fit with the adjustable headband and foam ear cups. Simple in-line controls make it easy to adjust the volume and mute the microphone. It's easy to set up, too. Just plug your headset and it works with common calling applications across almost all platforms and operating systems. Mini-jack.
