About these headphones (which I have not tried myself):
Some customers describe these headphones as having a "bass-heavy, well-balanced sound".

So it could be something for you :)
Regarding the sound emission towards the outside: it is a closed headphone, the emission towards the outside should be limited.
Otherwise, you can also ask
