My daughter got these for Christmas, and liked them so much I got them too. They fit perfectly in my ears and don't fall out too easily. I do wish the sensor was in a larger area but it stops me from accidentally hitting them. The sounds quality it great I had bought the candyskull pods first and tried them side by side and these were far better. Battery life lasts me four days or so and I listen for hours at work and home. They pickup sound very well for calls. I love the smooth slick case and the only problem with the smooth finish is sometimes it takes a minute to get them out of the case, not enough to be bothersome tho. I'd buy again!
