Doesn’t block the worst sounds much (high pitch & clanging). I can hear people talking, and it helps a little with group gatherings. I don’t think it will help you much more than most earplugs/noise cancelling headphones.

I love these. They hold 4 products from any range. Apart from the obvious, (headphones)
Nice and soft yet durable enough to carry my selection around without even noticing they're in my pocket. Great touch with the colour range.

Nice little pouch
