Ordering

How to order

  1. Pick a cable from the list below.
  2. Under Headphone connection, choose Standard 2-pin (0.78 mm).
  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

  • Match the marked side of the plug to the marked side of the socket. 2-pin polarity matters.
  • Recessed sockets (Blessing 3, KATO, Variations) take our standard 2-pin plug; you don’t need a special recessed plug.
