BenQ-Siemens Music Cable IHM-100

BenQ-Siemens Music Cable IHM-100

Postby TB » Fri Oct 01, 2010 4:12pm

Hey little fellows :D

A very interesting question that I've been wondering about for a long time...

This item: http://cgi.ebay.de/IHM-100-BenQ-Siemens ... 3a5f1fe899

Supposedly, it can be used with:
C81
E71, E81
EF82
EL71
M81
SF71, SL91

But it says that it can't be used with the EF81... why the hell? My theory is that, maybe because the EF81 is older than these models, it won't recognize the cable as a audio cable, and so won't be sending the audio signal through the port... but it's just a theory lol and I really wanted some of these, to connect the mobile to one hi-fi, for example...

Anyway, I could just order it, try it with my EF81 and, if it doesn't work, I have one E71, so it wouldn't be wasting money...

Whataya think? ^^

Hm.. EL71 and EF81 should have the same interface for audio.
It is stated in this thread: http://www.siemensplanet.com/forum/viewtopic.php?t=3300 (look at the audio interface schematic for EL71, EF81 etc)

So I bet that item on ebay would actually work on EF81, but I cannot guarantee it.

I've had E81, EF81, EL71 and SL91, and if I remember correctly, all of them could use the same headset..

Hi there Iver, thanks for replying... I don't know if I explained my doubt quite well... the cable will actually fit the EF81, the same way it fits the E71 and the EL71, because the port is the same, so it fits, but in that item's description it says it won't work with the EF81, so I just wonder if the mobile will recognize it as being a audio cable and send the audio signal through the cable instead of the speaker, that's my doubt... because, even managing to plug the cable in, I have some doubts that the mobile will recognize it and send the audio signal through there...

EDIT: just found other site, with the same item, without the EF81 stated there again...

I know that they use the same port/plug, nano lumberg. But my point was that the schematic for HHS-150 on the page I linked to is a circuit that works for EL71 (nano lumberg, FE75), C81, EF81 (nano lumberg, brew) and S68 amongst others. Also, I've got the HHS-150 headset and it did work on EL71, EF81, SL91 and E81. It is natural to believe that IHM-100 is somehow similar to HHS-150, which works on many nano lumberg phones with different platforms (mostly FE75 and BREW). But this is mere speculation. I don't understand why IHM-100 shouldn't work on EF81 when it is specified to work with similar phones like E81, EF82 and SL91 (at least they are both based on the same platform). On the other side, most of the phones listed as compatible were announced after EF81 (EF81: January 2006, the other phones: >= February 2006) (source: http://www.gsmarena.com). Therefore, maybe, IHM-100 was made to be compatible with all nano lumberg phones released after EF81? Again, this is mere speculation. If it wouldn't work on EF81, maybe only a software update or a patch would be needed?

Anyway, 4 bucks for an IHM-100 ain't much. And if it doesn't work, I'd mod its hardware to work, as in make it become recognized as a different audio accessory (f.ex HHS-150) (check out the thread I linked to earlier). Or wait, I'd rather just cut the ear plugs off my HHS-150 and solder RCA-plugs on it instead ^^

wow lol thanks for the info :) it should work with the EF81, I just don't get why they say it doesn't... anyway, if I actually manage to buy it, I'll post results. Again, I have an E71 too, so if it doesn't work with the EF81, I'll just use it with the E71, it's the same, just put the microSD in it and let it rock eheh I just got very interested in finding why the hell it doesn't work with the EF81 when it does with all the others... weeeeird... xD

And I believe, just speculating too, that the reason why it doesn't work with the EF81 is software related, something that an update would fix, but anyway, I don't think BenQ-Siemens will be releasing some new update anymore (:twisted: :twisted: :twisted: :twisted: :twisted: :twisted: ), and I have the latest firmware...

And about cutting of the HHS-150, noooo way lool I use 'em everyday... in fact, my EF81 its an all-around-music, I use it as a mp3 player, basically (and I have a mp3 player, a Creative Zen V, but prefer much more using the EF81 eheheheh)... that is why my battery's performance is going dooown and down (the battery is still the one that came with the phone, so...), and that's why I have two original and new BenQ-Siemens batteries, just waiting to be used :twisted: :twisted:

Well, the headset of my SL91, works with it (obviously and my EL71.
But on E81 it doesn't work.
Why?
I dunno. Maybe because the E81 was BenQ made? Probably.

Yeah, maybe... but both E71 and EF81 are Siemens made, and the first works and the second, apparently, doesn't... well, we're about to figure that out, I bought the cable, has already been shipped last Wednesday, so I'll be getting it soon, I hope...

So here are the latest news lol
Got the cable today, connected it to my hi-fi and it works flawlessly with E71 but, as I was expecting, when I connected it to the EF81, it simply didn't recognize it at all... the only response I got from the phone was the screen light turning on, but, when tried to put some music, the sound came through the phone, no sound from the hi-fi...

Then, I had this brilliant (not!) idea of trying to make the phone recognize the cable as a headset, so that it would send the audio signal through the cable... so, for not messing with the cable, I just picked some thin paper and put it on the cable, covering all the pins EXCEPT those three used to transmit the audio signal, hopping that I would manage to trick the phone.

Connected it to the phone and it recognized it as a headset, as I wanted :D

Then I finally put some music playin' again, hoping the sound would come through the hi-fi, but, but unfortunately again, there was no sound coming from the phone or from the hi-fi, so basically it was a waste of time LOL

Hopefully again, it works with the E71, so... ^^

Well, not is to solve the mystery, why they have these differences and what can we do to solve it.
Mostly looks like a "nano-lumberg version 1" and a "verson too"
Same look, different schematic?

It would be interesting to know if the cable is compatible with later models, like the SL91, SF71 (yes, it has Nano Lumberg 8)) and SL98.

How odd, it works with all MP3-capable Nano Lumberg-equipped phones, except the EF81... :?

Ah, but I now see they forgot the CL61 and the SL98! Anyone care to give me a cable to try it out? :D
I'd say it works with the former, and no idea about the latter.

maybe because the EF81 was one of the fist ever nano-lumberg phones to get out (along with the cute AL21), and after that they made improvements?

Actually, the AL21 has Slim Lumberg, but the other two triplets (A31 and AF51) do have Nano.

Well, I actually managed to have the EF81 detecting the cable BUT as headset (cheating a bit lol), because the cable plugged in by itself won't produce anything on the mobile, except for the screen lighting up lool

i mainly think that the problem here is that the cable has another 'entry' in it, let's say, i don't know what it is for, but maybe to charge the mobile at the same time you are listening?

Some images I took of the cable here:

Yes, it's for charging the phone simultaneously
