Quite satisfied, they have good sound and you have the option to choose whether to listen to the sound from the surrounding environment or to block it out. It has three sizes of silicone tips to fit well in any ear size.

UPDATE:
After almost 3 years of use, suddenly one of the two earbuds stopped working, it didn't turn on and the blue light didn't come on when I put them in the case, and I was disappointed. Just when I thought they had permanently died, I decided to leave them out of their case all night and the next morning I charged them for about 3 hours. They came back to life and since then they both work normally.
