Fostex T50RP 50th Anniversary Edition Info, Wiring, Replacement & Custom cables

TL;DR Any of our cables from this product collection (HC-3-Cs) are fully compatible with the Fostex T50 50th anniversary edition headphones!

The Fostex T50RP 50th anniversary edition headphones are here and we've been asked a bunch about these. We thought we'd make a summary page to point people in the right direction with these headphones.

WIRING / PINOUT

These use a 4 pole, locking 2.5mm (TRRS) connector, utilizing the pinout pictured below. Please note that a standard 90° 2.5mm connector will not work with these cans. We're stuck using the proprietary connector Fostex designed for this:

BALANCED?

Unlike their standard T50 / 20 / 40 RP counterparts, the T50 50th anniversary headphones are balanced capable. So no issues terminating these to a 4.4mm or full size XLR for balanced listening.

What cables should I get?
