It never happened before, when I wrote a positive review within few hours of receiving anything, I couldn't do that injustice to this amazing pair of earbuds. Fitting and comfort - just number 1, it fits so perfectly that gives you better than ANC experience, I literally can guarantee that. Calls and Music - I tried the old ones before and the new earbuds are lot lot better, extra bass, music quality was fantastic. I like the upgrade of magnetic casing, keeps it secure, I remember that was a drawback with the old gen. Below $300 I would say the best choice for full wireless earbuds. I must say really really impressed. Highly recommended.
