Problem with headset

[Felipe_Bozzoni]

I have a Xperia P, the headset that came with the phone spoiled, then bought a Sony MH750 headset, but the quality of sound is horrible, and I wonder if something with the phone or the headset that is defective

Hi,

It's hard to say from here if the phone or the headset is defective. I suggest that you try another headset in your phone and/or the headset in another phone to see if you can conclude what the cause is.
