What it is
The earphone-end connectors of an IEM cable, sold as left and right pairs for cable builders. MMCX is the round snap-on connector that lets the earpiece rotate; 0.78 mm 2-Pin uses two parallel pins in a flush housing. Both come with gold-plated contacts, left and right marking, and clear, black or metal housings, in packs of 1, 10 or 50 pairs.
Builders pair them with our braided cable core, headphone plugs and splitters to make complete cables.

FAQ
How are left and right marked?
Each pair has a left and a right connector marked with a color ring: blue for left, red for right. L and R lettering can be made to order.
Do you supply recessed 2-Pin connectors?
Our standard 2-Pin connectors are the flush type. Recessed and extended-housing versions are made to order; check which type your earphone sockets need, since they are not interchangeable on every model.
