I only bought these headphones 2 days ago but they are AMAZING! The fit is great...ear buds usually hurt my little ears but the small fittings are perfect, soft but secure. I took these headphones on a 10 km run yesterday to test how well they stay in place and the comfort...didn't move an inch the entire run, were really comfortable and the sound was just as great! I even really enjoyed that they have a tiny clip on the back that I could fasten to my shirt (thoughtful feature). Also, the connection is stable and I can be a fair distance from my device with them. So far I'm pretty impressed!
