    Bad sound from combo jack

    I have the EXACT same problem as this guy (even have the xperia headset).

    T420 combo jack - Lenovo Community

    In a nutshell, my Dell E6520 has a combo stereo/mic jack, into which I can insert a regular TRS headphone connector and get great sound. However, when I insert my TRRS xperia smartphone headphone/mic combo, it filters out a lot of frequencies UNLESS I press the microphone button.

    Since it works if I press the button, it does not seem to be a hardware problem (I can get great sound if I just keep the button pressed).

    Any ideas? Thanks.

    Wrong TRRS pinout. Get a headset that's compatible

    But then why does the headset work perfectly when the microphone button is pressed? Is there no way to default it that way?

    I'll just repeat it over and over again if you like :p

    What you can do, if you're DETERMINED to resolve this by not getting another headset, is to buy a TRRS socket and a TRRS jack plus a short length of 4-core cable, and solder the connections with them swapped around. However it's highly unlikely to be cheaper than buying a new headset, and it'll also add bulk.
