You may try EQing. Many people try to seek more balance that what a product has to over by default. EQing is a big way to get there
if something robust enough is available which can sometimes be rare without spending some cash on something.
There is one thing I will suggest. The Triple.Fi 10 runs a dual nozzle setup. Unfortunately this creates some sensitivity to positioning in the ear. This can become a time domain issue and create some incoherent nature with the sound. Over the ear for mean creates this incoherence between the mid-treble driver and bass drivers. They don't quite sound linked and the bass is a dominant presence. I have come to prefer wearing them down instead, rotating it 180 degrees in the ear and having the earphone tucked against the ear facing backwards. There are no reversed cords doing this either. They simply hang down instead. I tend to shape them forward a little as to prevent the cord weight from wanting to rotate the earphone in the ear. It's not as secure, but what it does for me is sync the mid-treble and bass together better and brings the mid-treble forward and more inline with the lower frequencies. Coherency goes up, and the whole presentation is just better. I have a pic of what I mean
This provided improved coherency for me, but it's not something everyone experiences. It really depends on how the earphone sits in the ear and how the canal is shaped. It's just a solution I've found for that issue. I realized it some time back and brought it up in a thread. I was cautious about the accuracy of the claim, but it was something I repeated later on after trying to keep them worn up over the ear for a while. Even the repeat showed that the presentation was just more coherent for me.
Now I would still EQ some in order to balance out the earphone. Frankly, these things are amazing balanced. They are fun left alone but get pretty critical evened out. These have long been one of my favorite and well regarded earphones that I've owned. These are earphones that I went back to after a slew of other products and was impressed by the quality of sound and level of refinement they offer. Are they perfect, not quite, but they're darn good and in the handful of the best IEMs I've used to date.
As for the muddy comment, I will agree that these are actually slightly muddy in the bass department. It's just that the notes are very thick in nature, very unusual for BA drivers, but if one carefully listens to the bass, it does tend to blurr a little bit, not much but some. It's not enough to really care about and not as bad as some dynamic drivers by a long shot, but it is there if you choose to be critical about how it reproduces the notes. I think it's just the thick nature of the notes that create that sense of muddiness with these earphones. So few BA earphones are like this. Something like the ER4S or Custom 3 offer thicker, more textured notes that step towards what the Triple.Fi 10 has, but it's not the same. The Triple.Fi 10 offers an uncanny amount of body yet still articulation and detail that isn't really matched by any other product I've heard.
