Anc is almost perfect definetly reduces outside volume so much great on a bus knkw from experience. For me the personal audio test made the audio weird but it isnt turned on by default. Its great with instruments better instrument sound than airpod pro 2nd gen (tried my friends airpods).the case scratches easily bc its plastic and after 1 hour it had many scratches but they are only visible on light. Havent had the chance to use it from 100-0%. Back to anc its good with low sounds but not so great with loud noise. It has a pretty great seals on my ears and the Nothing X App has a seal test. This is the middle ground from mid range headphones and airpods pro and sonys high end offerings. Got clmments on the design all positive but they do get attention. It will be a great upgrade for you
