I have uncooperative ears for in ear buds, makes it frustrating, I love to listen to music on runs and walks, and I hate wires to tangle or get in the way. These work great, sound is good, they have silicone ear bud sleeves to help keep them in place. Only complain is the bar with the volume and power button is a bit clunky and does sometimes tug on the ear bud. I would get these again as most others are too big for my tiny ears, and hope future versions improve the power bar location. I have had them about a month, have run in them, walked to the market and talked on the phone, the microphone sound is solid.
