An upgrade in every way to their previous earbuds. Better noise cancellation, better charging case, at least as good of fit (it feels just as secure as the last ones in my ears). Useable for long periods of time without discomfort (the previous ones would hurt my ear after awhile), I have used these from full to zero twice now without any notable discomfort. The sound is at least on par with the previous version, my brain says it’s better but my mind says it’s about the same.
