    does anyone know what this connector type is called? It's super annoying there's so many, though I must admit this connector is very comfy because it has a curve built in, and the cable goes right around your ear.

    it’s like a recessed 2 pin

    is this "QDC"?

    I only know that KZ call this type C-pin on their Bluetooth earhooks, in contrast to B-pin for the non-recessed version:

    Effect Audio just replied and called it “recessed 2 pin”. Satin Audio apparently calls it QDC

    But "QDC" just means "quick disconnect" and is used across industries to describe all manner of quick-disconnect fittings and connectors. If you want to refer to these connectors specifically, you should use a more specific name.

    If I’m not mistaken, it’s called the QDC connector because QDC uses them across all their in-ears. Ultimate Ears used to use that connector back in the UERM days.

    Also, Effect Audio calling them recessed further confuses the issue, as historically these have been the flush and recessed 2 pin connector types:

    RECESSED (as it fits recessed sockets like Unique Melody)

    Thanks, I'd never even heard of the QDC company.

    They are good folks. They do IEMs for artists/hi-fi as a side business to their Chinese military and secret agency stuff. I visited their main office few times, they have it on display there, some cool spy novel gear ;)

    SOCKETS: Sometimes 2-pin sockets are referred to as non-recessed (flush), recessed, and extruded.

    DIFFERENT TOPIC but hopefully helpful to somebody:
    FYI, regarding pin diameter, most pins are 0.78mm but remember there is some manufacturing variance in the pins and the sockets. Unless you have pins and sockets made by same supplier, there can be a stacking of tolerances and also some stretching of the sockets with cable swaps. These connectors are not made for lots of swapping back and forth.

    Are there any good accessories out there for cable management while stored? like some kind of winding stick or disc?

    Plenty of things like this around (which you could put inside a larger hard case):

    For storage/travel I always liked the old Shure hard cases, which had a central insert about which the cable could be wound. Their current cases, though, don't have this. You might be able to find something like this at a more reasonable price:

    that Shure case is great and I wish it still existed. I might 3D print something similar to the inner part to drop into cases I already have

    This reminds a bit of the packaging Apple had for their earphones which is really good. But also too specific

    I forgot about those Shure cases. Those were good.
