Marshall AUX-3 Replacement Boom Microphone — Black

About this pair

Despite the short title, this spare is a black 3.5 mm coiled AUX cable with a microphone for Marshall Major headphones — a wired lead with an inline mic module, not a cup-mounted boom arm. When the stock krouceny talk cable frays, loses the mic path, or the plug gets loose, this aftermarket mic-enabled lead restores office calls and phone talk without replacing the Major cups. SKU 174272 is the first listing of this type; sibling 174286 is variant 2 of the same coiled Major AUX family. Read the FAQ on the card before treating the part like a gaming boom stem.

A coiled AUX with microphone keeps the classic Marshall cable look while carrying call audio through the inline module. Treat the part as a plug-in headset cable swap: unplug the old lead and insert the new 3.5 mm plug fully. Stop if the jack does not match. Connector wiring (TRS vs TRRS) is not specified on the listing, so match the plug rings to your worn Major cable before you order a black twisted mic cord as a blind buy. Confirm TRRS vs TRS once — phones that need a four-pole plug will not forgive a three-pole substitute.

Black microphone for Marshall AUX-3 naming on this card still points at the Major talk cable use case — an inline call microphone lead for desk and commute wired mode. Remote or mute buttons are not listed; compare the inline module to your original if you need those controls. An aftermarket mic-enabled lead is enough when you only need the coiled cable and mic path back online. Office call wired backup is the everyday job: plug in, talk, and keep Bluetooth off when the battery is empty.

How to replace microphone on Marshall AUX-3 in practice means swapping the entire 3.5 mm Major talk cable, not clipping a boom onto the cup. The swap stays simple once the plug seats. This is not a standalone boom arm and not an over-ear cushion spare — ignore long-tail wording that drifts toward pads. If your worn lead still has readable ring counts on the plug, photograph it before ordering so the replacement 3.5 mm Major talk cable matches.
