I use the headphones in a rather small office, but with noisy colleagues. (We listen to music, talk a lot and loudly). Making calls with the Plantronics in Skype for Business is absolutely fun. My conversation partners only hear me. The microphones are so well aligned that the ambient noise is successfully muffled to a minimum. I would recommend the headphones again and again.

From my point of view, the USB-C variant is a bit of a tinkering solution. Basically, it is the same headphones that are charged via MicroUSB. However, the USB-C variant comes with a USB-C dongle instead of the USB-A dongle. If I understand correctly, they also supply the normal USB-A to MicroUSB cable, but also provide an adapter from USB-A to USB-C so that charging can take place via USB-C. Not a real USB-C product...

Ok

It's already in a previous question. One is USB-A charging/wired cable while the other USB-C.

The headphones have Bluetooth, a USB wireless adapter and an AUX connection. You can try connecting the USB wireless adapter to the TV, but I don't know if TVs support this. If the TV supports Bluetooth, you can connect the headphones to the TV via Bluetooth. If neither of these works, you can still connect the headphones to the TV with an AUX cable, which should be possible with any TV.

I had the same concern. The headset is surprisingly comfortable. The ears do not get warm compared to my previous headset of similar design and it remains very comfortable.

Hello, that is correct, it works without software. You can also configure the headphones via the app on your mobile phone.

I do not know. What it can do is distinguish between mobile calls and calls via sSkype in the office, or switch to the ringing device.
