Side-by-Side Comparison Jack Connectors

3.5 mm TRRS vs. XLR 3-Pin

Comparing 2 standards across 9 specifications. 9 key differences identified.

Comparing:
3.5 mm TRRS
XLR 3-Pin

3.5mm TRRS connectors transmit stereo audio plus a microphone signal over four conductors. CTIA wiring places ground on Ring 2 and mic on the sleeve; OMTP swaps ground to the sleeve and mic to Ring 2, causing muted or distorted audio when the two are mixed.

Standard 3-pin XLR audio connectors use Pin 1 for chassis ground/shield, Pin 2 for the positive (hot) signal, and Pin 3 for the negative (cold) signal. 48V phantom power is supplied equally across Pins 2 and 3 relative to Pin 1.
