The hemp is very soft and offers a unique and sustainable material for eco-conscious users. Returned and seller gave me a partial credit stating they were dirty and missing some materials. Love that theyre color coded. Soft, cushy, light. As soon as you are back in range it reconnects. I don’t see anything but an 800 number for support and didn’t get an answer there. I was looking for a more academic and clinical experience and am disappointed. The wiring has started to act up, so i am looking for a replacement. I was blown away by the clean and full sound from such a compact package. Love that they give you 2colors for the cap so you can switch it out whenever.
