Quick Sony EX-71 Question

[Squibbles]

I was about to purchase these off eBay for their isolation, but then another question came up:

I know that I can't hear external noises with these on, but can other people hear my music? Does it contain the music well?

Thanks.

They are the most non-leaky in ear buds I've come across. On full volume (French limited unfortunately) when lying on the desk in front of me I can barely hear them. When they're in my ears they're quite loud enough for me even on the Tube.

I hate hearing other people's music and so this was also quite important to me.

Thanks Alot!
That's all I needed to know.
Gonna go order these now.
