I am planning on buying these so I can use them at the library, do they leak?

What are other alternatives that offer no sound leak?

Thanks!

PS: should I consider the Sony MDR1RNC?

The DT770s should do a fairly good job of blocking noise.

They might be even better at blocking noise with the leather pads.

Not that much. Only someone sitting very close can hear a very faint sound
