Good enough to filter distractions and communicate, not good enough to record audio tracks or mix/master sound- Output adapter is flimsy and may easily rip if accidentally jerked too hard- Plastic mic wrapping is also flimsy & thin Worst straightener I have ever purchased . I love Keen, after the indestructible boots we got this winter for a very active 3 year old boy I ordered these. No matter how hard I tried, I could not get the screws into the holes. And it feels really good when asked are they comfy? I can say, oh definitely. The overall design looks sturdy, however, it’s not good if you’ll hang it over the door. I only gave it 3 stars because of the built quality. Thankfully they fit hubby who takes a size 11. And for the price, it was Very Worth It! I recommend these sandals they just look too cute.
