Hardware Issues: Headphones w/ Mic
 

I've tried putting in Apple Headphones w/ Mic, and they just give a ton load of static when completely pushed in, if I pull it slightly outward, to the second line on the jack, one side works, and sometimes both. Why does this happen?

I wanted to get a new pair of earbuds with a microphone, but I'm scared it won't be compatible with my N900.

Could you please name some?
Just an idea, would say, Skullcandy FMJ's w/ Mic work with the N900? Confirmation would be appreciated, thanks guys.

Re: Hardware Issues: Headphones w/ Mic
 

Yeah it does the same with my ipod earphones. (Not sure why) I bought a new pair of Sennheiser's, and they are good and work fine.
This thread may help http://talk.maemo.org/showthread.php?t=56389.
EDIT: The sennheiser's I use are the MM50 non-iphone variant.

Re: Hardware Issues: Headphones w/ Mic
 

Thanks, What Senheisser's did you get?

Re: Hardware Issues: Headphones w/ Mic
 

Nokia used one arrangement of rings in the headset jacks of their smartphones. Then, when Apple designed the iPhone, they used a different arrangement. All headsets made for the iPhone will behave as you've found your Apple headset to do.

There are a number of existing threads regarding this issue.

Hey could you please help me? I got a new pair of headphones, and these don't work either. Now Im headphoneless.. fml. Is there anyway to fix it?

Re: Hardware Issues: Headphones w/ Mic
 

HeadPHONE or HeadSET? A lot of confusion is created on this subforum with people not making the distinction.

In terms of HeadSETs, the above post explaining the iPhone wiring vs N900 wiring is true - no iPhone-intended headset will work properly with the N900.

In terms of HeadPHONEs, anything stereo (bar truly exotic headphones such as orthodynamics or electrostatics) *will* work. If you've bought HeadPHONEs and it doesn't work, either your N900's jack is dead (if you try plugging any other HeadPHONE into the jack and it doesn't work either) or the headphone is faulty.

Re: Hardware Issues: Headphones w/ Mic
 

yeah, its the headset.
Why is Nokia so "smart" or Apple.

Gosh, just wasted a ton load of money on this, now i can't do anything.

Re: Hardware Issues: Headphones w/ Mic
 

Apple is not the party to blame here - defo Nokia with their stupid headset implementation in the N900. And not just the wiring either (i.e. the lack of support for anything other the one button).

You could do what I did - which is to buy a WH-205 (ie. the standard N900 pack-in headset) on fleabay, snip, solder a volume control / standard headphone jack onto them and plug in the headPHONEs of your choice.

Re: Hardware Issues: Headphones w/ Mic
 

Is there any reprogramming or home hack to flip it around?

And also, is it possible to break the headphone jack cause I put it in anyways?

Re: Hardware Issues: Headphones w/ Mic
 

Punto, sorry to repost, but is there anyway to disable the Microphone, and just go on to Grounding?

Re: Hardware Issues: Headphones w/ Mic
 

Not to my knowledge (break jack).

Since it's not just a channel issue, I don't believe anyone's figured out whether the TR¹R²S connections can be remapped TR²R¹S by the N900 in firmware for starters- I've looked and certainly seen nothing.

If you're handy with a soldering iron, you could try and get hold of a TRRS jack and a TRRS socket to make a mini extension cable of sorts, and try swapping around connections to see if reversing the rings works.

Re: Hardware Issues: Headphones w/ Mic
 

For what it's worth, for the N900's headset jack, Nokia simply maintained the same pinout they have been using on devices for years, since long before the iPhone existed.

No. You'd need to wire up an external adapter.

No.

Re: Hardware Issues: Headphones w/ Mic
 

I hear you. Only of course it doesn't actually work with the Nokia wired remotes that have existed since before the iPhone existed.

Re: Hardware Issues: Headphones w/ Mic
 

Yes, that's certainly disappointing.

Re: Hardware Issues: Headphones w/ Mic
 

Yes. Get a Stereo extension cable. Plug it inbetween the iPhone headset and the N900. That should give you stereo sound only (no mic). But that kind of defeats the object, doesn't it?

Re: Hardware Issues: Headphones w/ Mic
 

No, I JUST WANNA LISTEN TO MUSIC >:(

Where can I get one of those?

Re: Hardware Issues: Headphones w/ Mic
 

arrgh dupe

Re: Hardware Issues: Headphones w/ Mic
 

Buy a proper headPHONE then!

You can either make one or find it at any audio store. The problem is that most store-bought extensions will be long, since they're... well, extensions.

Re: Hardware Issues: Headphones w/ Mic
 

LOL , well i didn't blow any money on em.

BUT IM 15.

Re: Hardware Issues: Headphones w/ Mic
 

Without knowing your country of residence, that's difficult to answer. In the U.S., Radio Shack, Amazon, or Monoprice would do the trick. Walmart or Target might even have what you need.

Elsewhere, I don't know.

Re: Hardware Issues: Headphones w/ Mic
 

And of course there's the issue of whether you really want to walk around like this:

Re: Hardware Issues: Headphones w/ Mic
 

The Source it is!

Re: Hardware Issues: Headphones w/ Mic
 

A 3.5mm stereo male to dual 3.5mm stereo female adapter would be smaller. Plus, you'd, uh, be ready to share you're audio with a friend. Yeah.

Re: Hardware Issues: Headphones w/ Mic
 

Funny how this came up, I am, at this time, working on creating an adapter so I can use a variety of headsets and microphones with my N900, PC, radios (I'm a ham radio operator), etc.

Today I bought a a pair of 3.5mm TRRS plugs for only a couple of bucks each from a local store (living in Phoenix makes this kinda easy). Now it's just a matter of getting some 4-wire cable (I ran out of time in that store before I had to go to work) and other connectors to do the job on the other end (one of which is proving very hard to find locally and/or cheaply). FWIW, there's no need to have the ridiculously long cable above if you can solder a bit.

One other idea I had (now out the window since I bought the 2 TRRS plugs) was using the N900's TV cable and just connecting the yellow video connector to a mic via another cable with RCA plugs on one end and the necessary jack on the other. There's no reason why this won't work with other people's projects, though.

BTW, that leaves a question: I still haven't read anywhere whether there is phantom voltage on the mic line to power an electret (condenser) mic. Both of the mics I want to use are dynamic so I'm wondering if this will create issues. Also I do not know the impedances of either the N900's output or my new headset's earphones...

Re: Hardware Issues: Headphones w/ Mic
 

If you do make one work for the N900, i'd be happy to buy one :)

Re: Hardware Issues: Headphones w/ Mic
 

I'm sure there are a bunch of better options (the above, only if you can get a compact Y-cable version - there are monolithic adapters of that sort available but obviously you'd end up with a giant plug stuck in the phone socket) but it comes down to what he can readily buy I guess.

I still vote for a headPHONE.

Re: Hardware Issues: Headphones w/ Mic
 

Im voting money;(

Re: Hardware Issues: Headphones w/ Mic
 

Well, put it this way - you can get a usable headphone better than most stuff they'd integrate into headSETs for little more than an adapter in many places.

Since you mentioned The Source, I assume you're... Eh.

Shopbot.ca has this source for the KSC75 for example, a popular on-ear-clip phone for audiophiles on extreme (ly low) budgets. http://www.ncix.com/products/index.p...2&promoid=1276

Re: Hardware Issues: Headphones w/ Mic
 

Sorry to be necrobumping here, but I bought the latest Koss Korta Pro model, and the same problem arises. Terrible noise plugging it all the way in. I was wondering, these TRRS-->TRRS adapters out there should work right?
Up to now I have found this one that seems to be the deal:
http://www.meelec.com/MEElectronic_T...tr-trrs-35.htm

But, interestingly enough there is one at DX.com too, but can anyone confirm that this should do the right remapping of the TRRS pin?

http://dx.com/p/3-5mm-4-conductor-tr...r-5-pcs-174101

I bought the damned headphones just because it HAD the mic, thought it would be a nice addition. See, my old koss porta pro finally broke.

I want to use the mic in them.
Would this work with the DX.com adapter? Or the first one?

Re: Hardware Issues: Headphones w/ Mic
 

Ah, never mind! My wife had a very short cable she had found just laying around at her work. I remember examining it and saw it was a 3.5mm female to 3.5mm male. I remember that I was thinknig "wow, this is the invention of the century, who would want this stupid thing? Extend your cable by 10cm?" I gave it to my little daughter to play with.

Now I know: Dammit, its a TRRS-->TRRS adapter. I tried it out and it works like a sharm. Even taking phone calls and using the mic!

There's a little white plastic sticker on it showing that it was bought here in Gothenburg Sweden in the most common electronics store chain we have "Clas Ohlson".

But: This story made me loathe iPhone and apple even a little more (if that is even possible).

Re: Hardware Issues: Headphones w/ Mic
 

Saw this post was active recently so I thought I'll reply:)

Recently dug out my old N900 to play with and found the same headset issues with my in-ear soundmagic e10's.

I live in China and found these 3.5 jack to 3.5 jack adaptors on a web shopping site (tmall). I'm not sure of the wiring and my chinese is not that great but they're cheap (8RMB) so I've just bought one to try out. I'll let you know if they work when they arrive though I'm not sure where to buy them in US or Europe.
