It really depends on your ear size
editor so YMMV.
I really liked the Anker P2's I had until I lost them. They are similar in shape to the Liberty's
contadino mentioned. The models that are not like that, such as Amazon's buds had too much weight in the wrong place and would not stay in my ears.
The P2's weren't noise cancelling but fitted in my earholes so well that they sealed out 99% of all noise, so much so I only used them on about 50% volume most of the time.
Buds with numerous sized tips to get a good fit is an essential imho. Preferably ones that have an app too so they can sense if they're isolating properly.
I'd use Amazon to ensure I could return them if I were you. Try a few brands out.
