Question about Sony Mdr-Ex650ap

I have recently started using the in-ears. I think they provide very good shielding from outside noise.

Hi Marco,

yes, the small driver sits comfortably behind the ear for added comfort and improved sound isolation.
Sensitivity measures how efficiently an electrical signal is converted into sound. Thanks to the ultra-high sensitivity, you can turn up the volume with these headphones without sacrificing clarity.
You can hear every single sound more clearly with less unwanted vibrations. Our MDR-EX650AP headphones feature a brass housing to minimise distortion and wide brass tubes for high sound stability. And the new angled earphone design with a secure fit ensures you hardly feel a thing when wearing them.
