[12 Hours] I like buy stuff from this store. Best customer service ever.

[Mono] Sound quality is great. Incoming and outgoing. Also love that it has a 3.5mm jack in addition to the USB

[1] I was looking for a headset/microphone combo that had good sound, was hard-wired for reliability and had a good microphone. I like over the ear and not on the ear. The on the ears ones start to hurt after a while because they press my ear on the temple of my reading glasses, these over the ear ones don't have that issue. So they seem well made, work great, comfortable, look good and come from a well known company. Perfect.

[12 Hours] Can't believe I waited so long to get this. Tries others but this one is so light and easy to use! I use it with my phone and the PC. Perfect!

[Closed-Back] This device pairs easily with my phone and computer so I can switch from my cell to a zoom seamlessly. So light and comfortable I tend to forget I have it on and leave the house or step in the shower.

[20 Hz to 20 kHz] My quest for my ideal headset is over. The EVOLVE 20 Microsoft Lync Stereo Headset by Jabra has what I want. Excellent mic, comfortable foam ear cushions, lightweight comfy headband, very good sound for music or voip. I tested and owned several others and either sold or trashed them. These are keepers.

[Yes] I love the product. I hunted through the packaging for two hours until I found the cleverly concealed USB piece for my computer (it is tucked into a tiny pocket inside the zipper of the carrying pouch, with no hint, documentation, or diagram provided)! Fortunately it was a day when B&H was closed so I got desperate and dug through every nook and cranny in detail, so I did find it. Great product. Online docs work great, once you find all the product parts!

[Mono] Purchased this as a gift for my wife since she works from home, and was tired of the corded Jabra headset. First fully charged day she said it lasted through her 8hr shift and could walk to the kitchen from her office which it upstairs without any dropouts. Clear voice since I did call to hear how it sounds, and headset audio I was told was great. Comfortable enough to wear all day. Got the Ms-Teams version everything was plug-n-play using an Lenovo Win-10 laptop.

[USB-C] The Jabra EVOLVE 20 UC Stereo Headset is a comfortable fit for a 4 hour shift. The earpieces are soft. The set doesn't bind or press in anywhere. The mic is nicely adjustable and the sound is clear when I am listening and background noise is suppressed; caller didn't even notice my other phone ringing across the room.

[Mono] In the age of ZOOM and working remotely, this is a necessity. The parties on the ZOOM or call can hear you clearly, and you can hear them without missing a word. The Bluetooth connection with MacBook Air works seamlessly once paired. Very pleased with this purchase.
