Great product I have PCOS and has help me a lot feel.better more energy, overall controls all my pcos. Awesome

I was a little reluctant to purchase these headphone since I haven't much success with "in ear" headphones in the past. Boy am I sure glad that I did!! These headphones rock! I'm no audiophile so I can't get into all the specifics about the ranges and such. These are a very comfortable headphones and they fit comfortably inside of my ears. The stay in my ears as well so I'm excited that I have nice headphones to use at the gym. I love the "hooks" on these headphones to keep them on your ears. The sound quality is awesome. The bass really kicks and the highs are very clear. I didn't have any issues connecting to these headphones. They also have pretty good range. On a side note, they didn't make my ears sweat like some other headphones have in the past.
