Got best service from them. I have too many headphones and earbuds. Well, I do now that I have these because I'll be using these the most. So much bang for the buck. A bit thick on bass when set flat, but with only a slight equalizer tweak, it's just right. I'm amazed at the sound for the price. Spend 2x as much and it likely won't be any better. Battery life is good, pairing was a snap, build quality is great.
