I just modded my V6.
Quick info: You don't have to do both of the mods. You can just choose to do one. The first mod is easily undo-able. Just put the foam back in. The second one is also kind of undo-able. You just have to tape the vent from inside. I personally didn't like recessed lower mids and not punchy bass, so I did this. There is a same mod for this for SRH940 as well, if anyone wants to try.
1. Remove the foam dampers in the drivers: Opens up the sound by a bit.
2. Drill a 1mm bass vent. This give much more impactful and punchy bass. It does sacrifice a tiny bit of clarity though. Also, lower mids become slightly more thicker, resulting in a warm/neutral sound. Treble stays more or less the same.
This is with SRH940 earpad.
I just did this because I was bored and I bought the V6 to experiment/mess around. I guess after all, the sound signature totally changed. It feels much more open and warm, but it does sacrifice a tiny bit of clarity.
*I forgot to mention this. You need to do a slight EQ to boost the lower mids. Once EQed a bit, modded V6 sounds magical.
