Just a thought, are you sure the red wire is 'auido-right'? This is not always the case. Perhaps if you have a sound file with only left or right audio you could check.

I'm 100% positive that the red is the right channel. If you look closely at the picture in this post you should just be able to make it out. I have tested with an audio file that says 'left' & 'right'.

I sense a modaco cottage-industry being born.

ie: Send your supplied USB headphones and £5 and an SAE and get someone smart with a soldering iron to make you an adaptor!

PS: I dont own one, and have the fine motor skills of a rhino, so dont ask me!!

Motorola used to do a off the shelf miniusb to 3.5 convertor or their razr

No idea whether it works on the tytn/hermes/Spvm3100 though - has anyone got one to try or a shop nearby they could try it?

The mini USB plug wont help I'm afraid. The socket on the M3100 is double sided and a standard USB plug only has connectors on one side - the wrong side!

Has anyone tried searching "EMU to 3.5" (Enhanced Mini USB) on Google? I have found the adaptor before but maybe it was not the correct side like mentioned above. "

I don't think that adapter will work. The main reason being that the USB connector shown looks like a standard Mini USB whereas the M3100 needs an Enahanced Mini USB connector. If you have a look at a normal mini USB cable and then have a look at the USB socket on the M3100 you will see that Mini USB has contacts on just one side but the socket on the M3100 has contacts on both sides. It's the 'other' side that has the audio connections.

I quite fancy the shorter version. Any idea if its possible to connect a microphone without the extra circuitry in the volume control box?

I notice there are a few resistors on the board, so not sure of they are needed for the mic?

Ideally I'd like a version like you have done, but with an additional 3.5" jack for a mic.

[FragMeister]

How about this for an idea?

Rather than getting a RK51F (stereo) how about a 4 pole 3.5mm socket (L32AZ) and then a 4 pole jack plug (QT65V).

Then: connect up all the wires (including the "mic") to the short end of the USB plug, as per Dade's version, and then using the remainder of the supplied headphones, put the 4-pole jack plug on the end.

I am hoping that with this I could retain the supplied headphones+mic for when I want a corded handsfree, but be able to use my nice sennheiser headphones the rest of the time.

One question is what will happen when using "regular" 3.5mm stereo headphones with the 4-pole socket? Will you still get full stereo sound?

Give me a little time and I will have a look into this.

I can tell you that if you plug a normal stereo jack into a 4 pole socket it't normally fine!

There seems to be a lot of pins on the enhanced mini USB socket, some of which on one side which is what a standard mini USB would use. Does anyone know if all the pins are used, if not, surely its possible to connect power input so that we can listen to our music while the device is being charged. For example, in-car use.

Hi guys n gals,

Just a note of caution - I had also made my own 3.5mm out of the headset... was happily using it for about 3 weeks, when one day the right earpiece had no sound.

Turns out that the mini USB socket on the phone had become loose (it did not feel loose, but when I moved the headset jack a little bit sometimes the sound comes back).

Sent the phone in for servicing, and they replaced the whole mainboard. Collected it 3 days later. Was happy with the service, but now worried about the durability of the mini USB socket. Afterall, it is used for the headset, charger and sync cable.

You might find this post helpful.

What you'll notice however, is that the plug on the headset supplied with the M3100 is single sided and only picks up the 6 connectors on the 'audio side' of the EMU socket.

This unfortunately makes modding the headset into a charger, sync and audio cable impossible!

Sorry to drag this topic back up again but did anyone manage to find out whether it was possible to wire a 4 pole 2.5mm socket to the usb adapter? I'm looking to plug the hermes into my bike communication system and it requires a 2.5mm connector for stereo audio and mic.

I've tried searching for adapters but have only been able to find ones that convert to 3.5mm stereo only with no mic.

cheers,

Thank you very much and I did notice them in my searches but they convert to 3 pole 3.5mm only, not the 4 pole 2.5mm connector I'm looking for.
