    So my left ear hears better then my right ear. I have got solved this by dropping the left channel volume in windows to 90% and this seems to even it up.

    However if you use something like WASAPI this ignores windows balance controls necessitating using your player's balance control. I wanted a hardware device to do this that would take software out of the picture.

    I did some googling and found this cheap thing on Amazon:
    https://www.amazon.com/gp/product/B0002J226O/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

    Only $9. The reviews are all over the place.

    It got here today. I set windows back to the default, and ran that through the left RCA of my Modi Multibit -> Asgard 2.

    I turned the volume all the way up on my Asgard 2 and dead silence. No audible anything.

    Listened to some music and I hear nothing cept my louder left ear I am used too at this point.

    I slowly turned the volume pot down on that thing till my soundstage was in the center of my head instead of off to the left.

    Not a bad little thing for $9. Does as advertised.

    Good to hear (pun not intended) that you found a solution and sorted the matter out.

    I'm also left eared, but right handed. The injustice!! Anyway, thanks for this.

    Oh my... the left hear problem.. I'm also a victim of this thing. Unfortunately in my case testing with sweeps and sines i have not only a prevalent left hear preference, but unfortunately it is more so at some frequencies, while some other are better heard right... so when i listen to a sweeps, it seems as if it has drank a little to much the evening before, because it goes like left left right left left right... Very annoying, cause then your mind start playing games and you ask yourself if you are hearing correct panning of various instruments in music.

    This imho is a thing better sorted in software than hardware if your source is a pc or a phone; loss of quality is non existent anyway if you use something like jriver, neutron or some other player that has 64 bit internal processing.

    Solutions i've found:

    On windows, depending on the player you use, you probably have a balance control. In jriver you can use either the parametric eq or the channel volume feature in the room correction. If you have only a total spectrum imbalance this will sort it.

    If you have particular frequencies imbalances then you have to eq. Fabfilter pro q 2 works well for this, find the problem frequency, correct it in L or R mode, then duplicate the band with the split function and make it specular (for example if you need - 4 at 8000hz R, you make two bands, -2 8000 R, + 2 8000 L. This preserve the overall volume at that frequency as intended, otherwise it can become weird sounding); easy peasy.

    Want better quality? Do this in pro Q, then copy all your setting in DMG equilibrium. Dmq equilibrium interface is a bitch for doing things like this, while you can do the correction really fast on pro q interface. But pro Q utilize a 1024 taps impulse response lenght, while equilibrium defaults at 65000 something, which is more transparent. Remember to use linear phase when adjusting for stereo coherency otherwise you can run in weird phase imbalances between channels. Oh, another important thing, if you use crossfeed, eq for coherency goes always after the crossfeed.

    In android phones, use neutron music player. There is a channel balance feature buried deep in the settings. I have not played much with specific frequencies imbalances here, but i suppose you can make an impulse response of your equalizer and run it into the neutron convolutor.

    Hope this helps, cause this problem drove me mad for the good part of a month! I know the software mentioned isn't inexpensive, but if you have to spend big $ on the rest of the chain only to hear everything shifted to the left or the right, or worse something that should be a little left becoming hard panned left... Well my priority would be to spend something on a good eq before buying further hardware. YMMV
