Bests & Worsts Reviews from Amazon

I bought these to conduct conference calls, but none of my devices detect that these have mics, such as OnePlus7, iPhone X, and macOS laptop. Disappointing. I want to send them back, but I recycled the box. UPDATE: Based off my original review, Anker reached out to me in order to rectify my issue and immediately issued me a new a pair of earbuds which are working as expected. In this regard, there customer service has been excellent and I would order products from them again.
