These earphones are far better than I thought they would be and better than any other earphones I've used. They are discreet and comfortable while you wear them. I haven't had an instance yet, even when walking or exercising, where they have fallen out for being too loose or have put too much pressure on my ears. Even if they did you are given sizing options with the earphones to make sure no matter what they fit well in your ear.
By far the greatest thing is the sound quality. These earphones sound as good as an amazing set of speakers or headphones. When playing music I can hear all the different layers and instruments very clearly as they don't sound as if they are compressed together. You actually can hear the bass which I have never found with any other earphones I have bought, and they have stereo sound which gives you that 360 degree feeling of music being played around you.
Very comfortable and very good quality. You can even choose to play music through a single earphone instead of both if you need to also be listening out for any other noises.
