Last year, I reviewed a new type of Clip-On earphone - the Soundpeats Clip1 Cuff. They don't leave a mark, they don't ache, they don't pinch, and most importantly they don't fall off. They paired instantly, accepted AAC as a high quality audio codec, the sound quality was excellent as was the microphone quality. Note, you need the PeatsAudio app not the "Soundpeats" app. I think that's excellent value for money.
