Ordering

How to order

  1. Pick a cable from the list below.
  2. Under Headphone connection, choose UE/UM/QDC 2PIN Legacy (qdc Anole, Neptune) or Standard 2-pin (0.78 mm) (qdc SUPERIOR, White Tiger II).
  3. Choose the player plug that matches the output you use most; see choosing the player plug.
  4. Not sure which socket your earphone has? Send us the model and a close photo of the socket before you order.

Before you order

Check your earphone

  • qdc Anole V14: some units have raised qdc-style sockets and others flush standard 2-pin. Send us a photo of the socket if you’re not sure.
  • qdc White Tiger II: qdc warns that thick 2-pin plugs can damage the socket.
  • KZ and CCA: if your stock cable is marked 0.75 mm, B-pin or C-pin, we can’t make a matching plug.
