Hifiman Sundara info, Wiring, Replacement & Custom Cables

TL;DR Any of our cables from this product collection (HC-9s) or this product collection (HC-9-THKs) are fully compatible with the Hifiman Sundara headphones!

Hifiman's Sundara is a dual entry headphone, taking 3.5mm (TRS or TS) connectors at each ear cup. 

Hifiman wires their headphones such that the use of TS or TRS 3.5mm connectors makes no functional difference to the performance of the headphone, provided they are wired properly. 


The 3.5mm connectors going to the headphone use a relatively standard pinout for 3.5mm headphone connections in the industry. See the diagram below:


The Sundara headphones are balanced capable, so there will be no issues if you'd like to use these headphones on common balanced output connections such as full size 4-pin XLR, 2.5mm and 4.4mm outputs.
