Jabra 01-0247 Quick Disconnect Wired Headset - Compatible with Desk Phones, Softphones & Mobile Devices - Perfect for Office, Call Center & Remote Work

I use this headset to conduct interviews. It is very well made and seems like it will be durable. Sound quality and noise isolation are excellent. I find myself grabbing it instead of the handset for ordinary calls because of its clarity.I don't need a separate amplifier because my excellent Polycom Soundpoint Pro SE-220 2-Line Conference Phone has one built-in. I did have to buy an adapter from Hello Direct (Amazon doesn't carry it) to plug it into the 2.5mm jack.At first the headset felt unstable - it adjusts on so many different dimensions and the spring power of the overhead loop is so light that it seemed to want to slip out of position. But I've learned to adjust it so it stays put, and the light pressure makes it very comfortable.
