Alrighty... I finally dug up the balls to carve up my brand new set of NDH-30's.. throwing a wrench into the "standard" procedure used with the NDH-20 the HPC port is in a slightly different location (offset further outboard than on the 20's) so I had to redesign the cutting jig to relocate the...

Will post some more as I go. This frame has a different hole placement, so I need to print a new jig and take some measurements to make sure I can cram that jack all up in there. That's a tomorrow project :) I have a very high confidence this will go as planned, despite needing a little rework.

It's time ;)

I am flattered!!! Their work is gorgeous. I'm a manufacturer in the canna vape space but am just a "user" here... look at my post history hahaha. I'm not sure I'm allowed to flip but would be happy to if there's a demand for it. I'm rather particular about the quality of my work and have...

The cable and jack inside the 20 and 30 are different pinouts, the cables are not interchangeable. I saw zeos chop his cable around the same time I got my set, so I know the cable itself can be converted/swapped to bal. The 30 is internally balanced, so you can use a custom TRRS cable to run it...

I just got my 30's a few weeks ago - am planning on doing this conversion. Will be happy to post pics. I bought my 30's new and they're worth every last penny!

Very first batch AKG K553 Pro's I got from massdrop when they released. I always hated the pads and fixed cable on these, but grew to love the sound. I wanted to convert these to Mk II's (detachable plug) and in doing so made some changes. I've put these things through the wringer and decided to...

My set is balanced so the BTR7 pushes them pretty hard :)

I've been searching all over the internet to find someone that has done this but keep coming up empty handed. I finally took a stab at it. IMO these are criminally underrated cans, but I HATE the cable nightmares they come with, and they really deserve to be able to run from a proper balanced 4...

Love these things. Decided to jazz them up a tad :)

Cans showed up as described in great working condition. Seller was courteous, prompt, and communicated effectively and thoroughly. Would certainly do business again! Thanks!
