Sound is great. I'm coming from a pair of LG tone infinims and because harman did the audio in those I was fully expecting to be sacrificing audio quality for the convenience of the W1 chip but I'm happy to say they are comparable. Comfort is where they blow all other neckband earbuds I've ever had away. The weight and bulk are entirely unnoticeable. Every other neckband earbud I've had I had to get used to the weight and or bulk and while I really enjoy the neckband form factor I hated having to get used to that. These are so light and slim I'm in love. One thing that surprised me when I first got them out of the box though was the flexibility of the band, I was expecting it to be much more rigid than it is. It's still early but these might be my favorite earbuds I've ever had.
