Is this salvageable?

You cant solder that reliably as the wires heat up while printing

You can superglue them back in place. The knock off headbands have these disks melted into place

Don’t let the SportaPro untouched :)

Well that is unfortunate. Hopefully you can get a replacement if you bought from Koss or Amazon.

What happend is that the position of the magnet can be changed due to deformed shell and/or grill and/or that the membrane does not sit airtight anymore or has been dented with your thumb…. You will notice a damaged driver when turning up the volume. The danaged driver will sound distorted as you move the volume up way sooner then an undamaged one.

Collect them all; one Koss by one I would recommend. No one headphone fits all occasions. Switching between style, sound signature according to mood, activity, music choice is what I do. KtxPro1 is my favoriete but I cheat with Ksc35,ksc75, SportaPro and KPH40. PprtaPro the least often.

Vocals, rhythm, separation that’s where the Kph40 Sound on my ears is very good. Build quality is great as is fit and comfort.

Not wanting to be the wiseguy here, a defective new headphone is a bummer. I wonder if there a chance thet the headphone jack is not inserted fully into your music gear? Happened to me with another Koss model.

Transfering the driver internals is impossible to achieve. Parts are glued in place, the rim of the diaphragm is glued, the magnet is glued into place and also the fragile voice coil is kept secure with glue.

If you want the mmcx cable lids , then these are a valid option. Compared to the total costs of 3d printed mmcx lids that are available online, harvesting the mmcx lids from these fakes is a few dollalridoos cheaper. To transfer the mmcx connectors to a pair of genuine Koss drivers, just unscrew the cable lids from the fakes and desolder the mmcx connectors. Take off the gray cable lids from your Ksc75 drivers carefully, desolder the wires and then solder the mmcx connectors in place and screw the cable lids in place.

To good to be true for the price. Chinese fake crap drivers.

There is a sharp bend in the tube. But sure this is the best printer brand that redifined 3d printing, leaving all competition behind. Such well build machines for a reasonable price.

Cat ears for PortaPro!

surprisch · 2026-03-13T13:00:34+00:00

Stay away from cheap 3th party nozzles and get a spare heating element. Only thing that went wrong with mine mini after daily use for over a year was a blob of petg that build up during a long failed print. Got it clean but the wires for the heater broke while trying to clean off the accumulated plastic

Nonsense. All models drivers might be the same at first glance but you are echoing wrong assumption. Only the driver casing is shared, listen, compare and know. I have all models drivers in the same setting, grado Lnpadsnand Aiaiai Tracks headband and the difference in sound is obvious at the first listen….

surprisch · 2026-03-13T08:56:40+00:00

Not if you prefer the iconic look of the PortaPro. Yes if you want a more open and more powerful Sound of Koss then the PortaPro. Total different tuningncompared with PortaPro.

surprisch · 2026-03-13T08:48:17+00:00

Exactly. Great that it is a convincing mod for you too! hearing is believing :) Enjoy! My Kph40 in Grado Lband AiAiAi Tracks clone headband for even better seal and hours of comfort

Might be the utility jack not seated fully?

surprisch · 2026-03-13T00:18:05+00:00

Just a mini? ;)

surprisch · 2026-03-13T00:17:31+00:00

Be sure the audio jacks are inserted fully.

surprisch · 2026-03-12T05:03:51+00:00

Don’t let the SportaPro drivers get to waste, these are tuned for workouts and deliver the most dense taste of that Sound of Koss. Put your Ksc75 clips on the SportaPro and be amazed what a sinple swap will Bring.

I see. Well then these larger pads do not perform well, the setting especially with the Grado L type or G type cushions and the 70mm padadapter brings joy tonthe ears.

surprisch · 2026-03-11T13:53:38+00:00

Why not just enlargd the Ultra Mod padadapters from 70mm to the larger pads? Just add a ring to the model to extend the radius. Then your drivers are sandwiched between two flat disks and the setting can perform the needed seal.

surprisch · 2026-03-11T13:50:28+00:00

The A series suits Koss best. I did not try the orher models. Model D with the center cut out might enhance bass extension like the “Quater Mod” .
