The KZ ZS10 Pro, ZS10 Pro X, ZSN, ZSN Pro and ZSN Pro X use KZ’s raised “C-pin” sockets with 0.75 mm pins. A standard 0.78 mm plug is the wrong size.

Ordering

How to order

Pick a cable from the list below.
Under Headphone connection, choose KZ C-pin 0.75 2PIN.
Choose the player plug that matches the output you use most; see choosing the player plug.
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

The pins sit inside a raised housing on C-pin sockets. If yours come out of a flat surface, choose the flat 0.75 mm plug instead.
Match the marked side of the plug to the marked side of the socket. 2-pin polarity matters.
