I just purchased a new smartphone just a month ago from sony. Known as sony xperia tipo which i found very useful under the subjected price tag. I ordered it on flipkart the phone is good and working awesome but the main problem which i don't aspect from sony is it's headphone quality.

The headphone is not up to the mark and didn't produces nice voice quality. So, what can i do please suggest.

thanks in advance.

it could be a manufacturing defect i would suggest you to go service center and get your problem fixed.
