2.5mm TRRS vs. 6.35mm TS
Comparing 2 standards across 8 specifications. 8 key differences identified.
Comparing:
2.5mm TRRS
6.35mm TS
2.5mm TRRS adds a microphone conductor to the 2.5mm TRS jack, following the same CTIA or OMTP wiring conventions as 3.5mm TRRS. It served as a mobile phone headset jack -- including on older Nokia handsets -- before 3.5mm became the universal smartphone headset size.
6.35mm TS (Tip-Sleeve) is the 2-conductor version of the quarter-inch phone connector, carrying a single unbalanced mono signal. It's the standard connector for electric guitar and instrument cables, unchanged in essentials since its telephone-switchboard origins.
