I am looking for wireless headphones with a microphone to be worn in the gym. My ears have an atypical inner ear structure and thus none of the so called IEMs that are 'guaranteed not to fall' work for me. I am looking at preferably bluetooth 5, a hook like design that keeps the buds in place and a microphone that will allow me to answer calls while I am working out. Any suggestions would be appreciated. Budget is around USD 100.
