A:Answer Although I have not used them with Zoom or online classes, I believe they would work with those programs. They do have hands free calling feature. They easily connect via Bluetooth to my laptop, iPhone, and iPad. I have only used them to listen to music or watch movies/TV with apps such as YouTube, Amazon Prime, Netflix, Hulu and many more streaming services. The sound is very clear and drowns out most noises...unless really loud. Great product for the price. I’ve been so happy with the headphones, I bought another one for my sister. She loves the headphones, too. I definitely recommend them.
