    Guys what are keywords to find MMCX parts for earbud? My search returns mostly Bluetooth parts in aliexpress.

    Try searching for "mmcx socket".

    If it can help, here is the link of the MMCX PINs I always buy from ali (good seller and nice package, I recommend).
    A bit expensive but didn't found cheaper for now for 10 pairs (at this exact dimensions). Excellent quality, and all my units are working perfectly for now :ok_hand:

    Thanks. I might try to get 2 pair. One for earbud and one to fix my xe800 iem.

    Edit * maybe 3 pair, my piston also in dire need of repair (if I can find a way to open it.)

    Edit 2

    Those 150 ohm, is there any reference (to common earbud) in how they sound? Seems interesting

    With the driver connections nearest you, + is on the left

    In each driver, you need to find a mark that identifies the side with the same polarity solder connector.

    For example, in each of the 600ohm drivers (see photos), there is a RED dot that identifies the same polarity solder point side.
    In the 150ohm drivers (see photos), the same polarity side is marked with a BLACK line (and some color painted in that side metal).

    So for 600ohm one, the red dot side means the polarity (+) side and the opposite side is ground (-)?
    And for 150ohm one, the black line side is polarity (+) and the opposite side is ground (-)?
     
  14. Merlin-PT
    Yes, I use the color mark in the drivers as the positive and no mark as ground.
