Sound pretty good. Really wish it has a transparency mode like my pixel 2 buds. Also wish the charger was black. But the one thing that is a major flaw is your can hear every movement from the lanyard. Similar to putting two cans together with string when you were a kid. It's quite loud and very annoying. Depending on how loud your music is you can hear it over music and or a call. only other thing I'd add is a clip to use lanyard in case you are only using one earbud.

The passive noise cancellation works well. I am glad there were 3 different cap sizes so it fit in my ears well. I love the design!

Sometimes the audio cuts out maybe just because it triggers, Siri or something. I do wish the housing was metal. But that would probably contain more heat and ruin the earbuds. It does have more distortion in base than I’d like but that’s OK. I’m into clarity.
