What is interesting is M/S Teams sees the Sennheiser USB dongle as an available USB input device labeled "Sennheiser BTD 800 USB for Lync". I noticed recently that They came out with a new version of this thats a little more heavy duty, but also more expensive. I hated to send them back but ,I couldn?t get my foot in them. Press the X button to Apply these changes. These fit well, with nice materials and detailing, modern but not flashy--like the suede, synthetic uppers, and especially the long, round, high quality shoestrings--ease to lace and tie. Was easy to connect to my phone, once turned on, they automatically paired. The reason I downgraded to 4 stars is the little "lip" at the heel which defeats the purpose of a mule. I am not happy. The noise you imagined, is how loud they are, lol) The weight is comforting and the fabric is very soft.
