    The Official 64 Audio Thread | apex & tia Technologies

    Just received the M12 apex module for my A12t, I think it's a really good pairing.

    Drop + Ultrasone Signature X Headphones Discussion

    and if you watch till 8:52, you'll notice that they might've installed the wrong plate on the right cup (the cut off portion's of the plate should be symmetrical on both sides, so that the sound enters the port angled slightly in front of either ears) they accidentally used the same plate for...
