Serious Question

[Alevity]

It's weird how the Audio Technicas I have are only on-ear, have 50mm drivers and are open back, yet they leak way less noise and do a ton of noise canselation when actual sound is played.

It's the on ear design so it only goes to your ears. Also beats have an opening on the cups if you swivel them you can see it where it connects to the band. Sound can come out of there.
