In my case it's about 11cm - but it's older and may have expanded. It falls off my head from time to time... Otherwise recommendable!

The "DUO" is equipped with a USB-C plug and the stereo version has a USB-A plug. With stereo, the headsets have speakers on the left and right. So if you also want to use the headset for music, I would recommend a stereo. It is also a question of which variant is more comfortable for you. "MS" and "UC" differ in certification. MS stands for Microsoft certification and is therefore optimised for Office/Teams and Skype products. The question here is with which software you will use the headset.

Hallo. Voila Huawei CM20 (USB C, 3.5mm)

These headphones are wired (mini-jack and USB interface) and are primarily suitable as a telephone headset on the PC. For iPhone, I recommend either in-ear or closed earphones with Bluetooth or headphones that you connect to the lightening port using an adapter.

That is possible, depending on the adapter for the 3.5mm jack from the Jabra.

The difference between home and work is that at work you may have a computer specialist who has done the setup work for you. And yes, they don't just plug and unplug cables or reboot a computer...

Hello, I cannot answer this question because I do not use this connection. I used Bluetooth. But this did work. But I assume that if the jack fits on the Lightning adapter, this will also work. Mfg

Yes, this works, perhaps Jabra Direct still needs to be downloaded for call control; https://www.jabra.com.de/software-and-services/jabra-direct

Hello Jonas - that's no problem at all. The headset consists of two parts: A USB connector with "control console" (preamplifier with function keys for telephony and volume) and a detachable headphone part (cable length approx. 1.2m) which has a mini-jack. It fits into the iPhone. You just don't have any control buttons on the cable (like with the original Apple headset). But the quality of the headphones is good. Speech quality through the microphone is also good. We have 6 such "sets" in our office for softphones and Skype and are very satisfied. I also use them on my iPhone now and then. Hope this helps you with your purchase decision ;-)

It works fine for me with Skype but not always with FaceTime.

I can't answer that because I don't use Appel products.
