Default [Q] Problem with the aux connector

Hello, I bought new headphons (AKG Q350) and I noticed that when I connect it to my phone the music sounds bad, in the computer it works well and the music sounds good.
I saw the aux connector has 3 stripes (I guess because it has mic), and when i pulled the connector a little bit out the music sounds good, but it's hard to hear music that way.
Is there any solution? Maybe an adaptor?

Thanks.
