r/kossmods

Hey folks! Just wanted to give you an update. As I mentioned, Fiona said they are working on the issues. Keep in mind, Fiona is just a customer service rep... She can't program in Linux!

Turns out, HibyLink on the R1 I sent doesn't really matter. My friend's daughter is getting a Hiby R1, with Koss PortaPros (used. That's like 10 years old!)

So it is a happy ending after all, at least I'm my case. But I think Reddit saved the day cause it got me in touch with Joe, so now I feel like I have personal connection with Hiby.

Anyhoos....v have a good night, all

These are my modded kph30is. Geekroa comfort pads, etsy 3d printed suspension strap and reinforcements for the headband. I got the Koss USBc to 3.5 cord that is 4 bands. A 3.5 to 4.4 adapter into a 4.4 extension cord into my Fiio R2R Dac/Amp. The Kph30is sound even better with some extra juice. They sound more open and dynamic. The mid bass is cleaner.

(Pictured: KSC75 drivers + Yaxi pads + Parts Express headband)

TLDR:

Is there a closed-back driver with the same clipping mechanism as the KSC75/Porta Pro?

Or, if not... is there another pair of super lightweight, swivel-ey, on-ear headphones that might work instead?

Essentially, what I'm trying to achieve is this exact same setup, but with a closed back. They're amazingly comfortable, and because this headband is so flimsy (and flexible), they're also super comfortable to use with only one ear (i.e. taking off one driver and tucking it behind your ear).

I had an old set of ksc75's laying around somewhere and bought the bits and doodads needed for the mmcx mod. Got another set, because I've been getting these headphones for years. Didn't know they had a cult following. I did get a parts express headband for my other set and a two pack of Yaxi Pads.

Love these guys. Never been an iem fan. They have just been my default for years

I noticed the headset version has a screw where the mic attaches, and now I’m curious if all Porta Pros share the same structure or if it’s just a manufacturing shortcut.

I found a broken headset version locally and wondered if the mic could be transplanted to a regular Porta Pro.

i installed mmcx connectors on my kph40s but theres a bit of a wobble whenever the cable is inserted which causes the audio to cut out, any advice on this?

These headphones at target have a headband that fits perfectly with ksc75, nice little $2 headband for those looking :3

They're just starting to roll in, but put together a little list of some of the early unboxing/reactions below I've seen for anyone interested. More unboxings vids will be rolling in with full reviews in the coming weeks. I believe we sent out a bout 30 review samples. We send samples to a full array of reviewers from casual listeners to audiophiles who will measure and go over every last detail.
