TRRS Pinouts for Desire-like proper headphones without issues of direct plugging in

---

Sup all would anyone have the actual TRRS pinouts for the audio jack for the desire I would like to make a up a lead that will allow me to plug an ordinary pair of headphones in using a proper TRRS jack instead of a TRS jack. thanks. There are definately issues plugging in a headphone directly or maybe it is my unit faulty?

Edited, this topic will show you the best way to connect your headphones to your desire as some people will experiance problems with pluggin in normal 3.5 jack plug headphones, this is due to the desire using a trrs socket for the microphone instead of a trs socket that normal headphones use.

pretty sure it is:
tip - left audio
ring 1 (closest to tip) - right audio
ring 2 - data of some kind
shield - ground

Hope this helps

cheers for that, im having some peeps tell me that i can just plug in an ordinary pair of headphones into the phone without any ill effects, i am concerned that i will have a problem because headphones are trs jacks and the desire has the trrs 3.5 jack. can anyone confirm any details on this for me please

nah you can use a normal TRS 3.5mm jack with no problems. I guess that when you use a normal TRS jack then shield and ring 2 on the connector are both connected to shield on the jack so it adjusts the software accordingly. But yea, no problems.

cheers for that

edited, we have since discovered that this is not the case, please read the entire topic for the correct way to connect headphones to the desire.

standard 3,5 mm (TRS) headphones DO CAUSE ISSUES

Was about to resend my HTC Desire, because it randomly called, skipped music stopped the music, FM-radio freeze etc. from the moment I connected my high-end 3,5mm headphone (TRS type: 3 contacts).

No issues with the standard headset delivered with the HTC Desire (TRRS type: 3,5mm 4 contacts).

So, you might need a TRS -> TRRS adapter.

Anyone with other experiences???

Basically what I have found is that many of the normal headphones are not working correctly because it is a trrs socket that is used. To me this would mean that normal headphones shouldnt be used, I have tried various headphones but there are definately issues with them,
The main issue I was having was as you have said above and also the base wasnt right with them

I have since bought this
http://cgi.ebay.co.uk/ws/eBayISAPI.d...=STRK:MEWNX:IT

which arrive today and when I am using this in conjunction with my headphones I now have the proper base to the set and NONE of the problems I was having when i was plugging them into the phone directly......... they just didnt sound right, now using griffin smarttalk this i can definately tell the difference now especially in the base, also this unit will lower the volume and allow you to make a call automatically with built in mike, clicking it twice doesnt skip the track suggested instead it will ring the last number dialled in the phone so a bonus actually to me :P
the straight adapters ie trrs to trs are very nearly the same price as this if not more expensive so i would recommend this all day long to you. At £9.75 delivered bargain m8, bought late evening on the 20th arrived this morning what more can i say, but if you are having issues it is definately in my eyes because of the difference in the trrs socket to the trs socket,
the base is fantastic on this phone now, before it was terrible, now i just need an equaliser to remove some of it :P

When you speak of "normal headphones", are you referring to simple 3.5 TRS headphones, or headphones with a mic ?

Cause if the majority of the headphones (without mic I mean) won't properly work with the Desire, it's a major flaw according to me.

I confirm: TRS (3 contacts, without mic) do not work...

...I tried 4 different 3,5mm stereo headsets (TRS type, 3 pole, without mic). NONE of them worked correctly (phenomenons as described above).

When you plug a 3 pole TRS headphone in the Desire 4 pole TRRS headphone output, a short circuit is generated between the first 2 internal contacts (seen from connector input: ground + control line).
I suspect that the Desire firmware cannot detect/handle this situation, and so it causes random actions (prev, next, call numbers, stop, play, ....)

I suspect that this issue could be solved with a firmware upgrade....

there is no way they would release hardware with a 3.5mm socket that you cant plug a 3.5mm jack into right? the firmware does detect when you use a TRS instead of a TRRS. You get a different icon on your notification bar for each of them. As ive said before my AKG's have worked perfectly so far and have shown none of the problems listed above.
