I like them quite a bit. Getting rid of any length of cord was a bigger deal than I thought it would be.
I don’t notice the sound being any better or worse than other earbuds I’ve used. Definitely not noise-cancelling in any sense. I do not know how I’ve managed not to lose them, but I haven’t.
What I like about them:
1) Comfortable. Somehow, they stay in when I run. “Cord slap” from anything with wires used to drive me nuts.
2) Battery life. Charges quickly in the case as well. They don’t drain your phone’s battery - that’s nonsensical.
3) Waterproof. They’re not advertised as being waterproof, but I have sent mine through the wash and dry cycle three times and no ill-effects. I also ran the case over with the car. They are apparently indestructible.
4) The signal does not drop out which was an issue with some of the bluetooth sets I’ve had.
