I personally prefer to hear the world completely and be a bit zen in my own thoughts when cycling (even if my thoughts are mostly just internally cussing out the hills), however if you do want to listen to music while cycling without blocking situational awareness bone conduction headphones are pretty good - like not winning any awards sonically but it’s good enough. Shokz used to be the best but like I said none of them sound that good so perhaps as well to just use aliexpress for some non brand version.
