Default Z2 with Sony MH-EX300AP

Hi Guys,

I tried using the Sony MH-EX300AP with my Z2. The headset button acts weird. When I press it either randomly increases volume, or decreases volume, or starts the music player, or acts like the app key. Its not consistent.
Has anyone else tried it with the Z2?

Also, any suggestions on a decent earphones with volume rockers + Button that works with the Z2?
If I have helped you, hit the THANKS button!!
