Problem with speakers or is it normal?

[DonnyDonster]

First off, this is my first time buying a Sony smartphone and I love it; it replaced my old Prism II and Sony Walkman NWZ-E465.

After using it for about a week, I realized something odd. The speakers play music from one end, which makes me wonder if this normal or not. If it is not normal, I could send to the Sony store nearby since I have a 2 year warranty and a Accidental Damage plan on it. 

Oh and here's the video of the "problem": Donny's Z1 Compact
