Headphone Jack Specification on Samsung Mobiles

I am trying to ascertain the specification for the headphone socket for current Samsung Mobile phones before the introduction of USB-C.

We are a Village Hall in the UK and hirers often want to connect their Samsung phones to our audio system to play back music from their phones. We have a range of connectors from:-

  • 3.5mm TS, (Tip, sleeve - normally Mono output I believe)
  • 3.5mm TRS (Tip, Ring, Sleeve - normally Stereo Output)
  • 3.5mm TRRS (Tip, Ring, Ring, Sleeve - Introduced to allow headphones with microphone??)

The latter 3.5mm TRRS being the one I believe is the one compatible with most modern Samsung phones and certainly the official Samsung EO-IA500 seem to have a TRRS jack plug.

We use a lead with a 3.5mm TRRS Jack plug for Samsung mobiles and for some it works (the audio output from the phone stops when plugged in and transfers to the amp input) but for some it does not.

I have removed cases from phones to ensure the plug is inserted fully but it still does not connect.

Are there any peculiarities with some samsung phone models?

Also do you know if you can safely use a TRS jack which doesn't have the microphone connections

Many thanks in advance
