Introducing backwards compatible 3.5mm 5 pole TRRRS audio plug and jack system

Bringing affordable HiFi Binaural sound to mobile devices everywhere!


Standard 3.5mm TRS/TRRS (Tip, Ring, Sleeve) jacks and plugs have been used for decades. They are featured in billions of audio devices all around the world, including all currently used smartphones. Major limitation of this design is a use of only four separate communication lines. There has been virtually no imporvements to this iterface for many, many years, Until now.

MAX Solutions found a way to modify the old TRS/TRRS standard in order to add one more separate Input/Output line.  MAX TRRRS jacks and plugs allow for using five separate communication lines. Unique feature of this connector system is its backwards compatibility with existing TRS and TRRS standards. That’s right, all legacy audio  plugs and jacks are compatible with MAX TRRRS plugs and jacks. Therefore all existing audio devices and their accessories could be successfully used with the new MAX TRRRS system.

Adding one more communication channel to the old system creates many opportunities for implementing advanced audio accessories. Active Noise Cancelling, Binaural Sound recording, Balanced Audio listening and affordableHiFi Personal Amplifiers/Hearing Aids are just a few.

Differentiation is just one of many benefits  MAX TRRRS connector system offers to system architects designing mobile devices and their accessories. It is a missing link between a digital world of a smartphone chipset and an analogue world of external audio instruments.

MAX 3.5mm TRRRS audio connectors are a reliable,  scalable, affordable solution that can be implemented into OEMs designs immediately.

All our plugs and jacks are backwards compatible with ITU-T P.381 and comply to brand new P.382 (P.MMIC) standard for 3.5mm TRRRS systems.
