Love using these at the gym! Excellent sound and stays in my ears. Battery life lasts multiple gym sessions. Only concern is the wire is thinner than I would like it to be since I have a history of pulling the wire. No problems so far. Good product! Would recommend.

They stay in my ears while running. I only use them for music while running, not anything else. I bought Koss because they used to be made in Milwaukee, my home town and it did come from a Milwaukee address but I don't know where they are made. They work good and I will buy another pair for $37

My favorite headphone company!

The best company.
