bluetooth stereo headset for bikers helmets ???

Hello
the Jabra bluetooth headset (http://www.jabra.com/) seems to be fine!
But I want to use something like that fitting inside a motorbikers helmet!
Does anybody has an idea where to find a stereo headset (with a bluetooth dongle like that from jabra) fitting in a helmet?
Also I am looking for a good small extern stereo microphone for the XDA!
thanks for your informations

Audio input on the XDA is mono.

thanks for this hint concerning the audio input!
and where can I get a mono microphone with a fitting plug?

There's an accessory (not off the top of my head right now...) that converts between a 2.5 mm headset jack and the XDA's headset connector, and another one that does mic 2.5mm and stereo headset 3.5 mm.
Or solder something yourself... All the info is on
http://xda-developers.com/connectors

I know this isnt as high tech as a Bluetooth headset such as the Jabra... but as a low tech solution, Why not just use the headset that comes with the xda? You can certainly improve the ear fitting with some replacement ear sponges. or even better, slice into the cabling, and replace the earpieces with the SONY headphones that are like mini "in-ear defenders"
Quick tip: to solder headphone cables, use a soldering iron with a little cored solder to melt away and tin the very thin coating on the exposed cables, as headphone cables don't have sleeving in the traditional way. Dont hold it on for too long though!
Sorry, I can't quote any model numbers for the sony headphones, but the nice design feature is that
1) They are inside the ear, so it wont interfere with getting your helmet on/off
2) The Bass response with these headphones are even better than the standard xda headset. Because they are a snug fit like an industrial ear plug, so the ear canal resonates the sound better without losses. In a noisy environment you should find this better, e.g. with the roaring of a bike engine.
Advantage of modding with the standard headsetYou can modify the push to talk button by opening the pod and wiring a switch in parrallel to your handlebars, something thats easy to use with big bike gloves on, e.g. an automotive switch from Halfords. And of course the most important part, you get the xda four pole 2.5mm connector, which is very difficult to get hold of!
The other part of the push to talk switch "pod" on the xda headset is the microphone, so you could mount it somewhere in the part of the helmet near your mouth.
Obviously these ideas will need some "interconnect cables", from your xda to your handlebars, and from either to your helmet, I did see a posting with a motorbike cradle mount somewhere on this site.
Connectors
You should be able to get an inline solderable coupling connector (male & female) respectively from your local electronics shop or http://www.maplin.co.uk a small 3.5mm connector will suffice.
Obviously for the mic you need two or three connectors depending on how you rig it up.
You can get away with a mono one and one with three (in other words a normal stereo one) for the headphones, which has three poles
Headphones (stereo 3.5mm solderable plug & coupler)
1) Left
2) Right
3) Ground
Microphone (mono 3.5mm solderable plug & coupler)
1) Signal
2) Ground
Switch (mono 3.5mm solderable plug & coupler)
1) from pod button contacts
2) from pod button contacts
Obviously if you're not keen on using the phone while riding, then dont bother with the mic, switch etc, and just make up the headphones for music etc.
If this is the case, just buy the sony headphones and use a 2.5mm stereo to 3.5mm adapter (available at most maplin stores)
I've already done this mod using a replacement xda headset bought from expansys.com for a cassette adapter for in-car use. And have had many hours of music listening in between and during GPS instructions on long journeys!
Software called "Withmp3" is very good for in-car music playback (Its just like Winamp) because you can assign hardware buttons to skip tracks or stop the music. Even while using Tom-Tom navigator for example.

by far the safest way to do this is look at the communication/intercom systems currently on offer from motorcycle suppliers. i know no biker is ever going to have an accident, but things sticking in ears is probably not a good idea if head does hit the road.
i am 'lucky' enough to have a bike already fitted out with passenger intercom, radio and 'phone connection but i'm damned if i can find the right sort of 'phone connector and the bike manufacturer is about 2 years behind. so i suppose i'll have to find someone who can make one. any ideas?

Motorola HS-830!
Bought two recently and they work just great!
Except for the fact that XDA/QTEK/etc... can't send audio, so I can't listen to MP3 using this helmet headset.
Anyhow, you can either use the helmet headset for phone calls or music (using iPAQ) or connect both helmet headsets to have a two way conversation with your passenger!
Work just great, and it comes with a neck lace, when not on the bike!

Audio bluetooth routing...
I found on this forum very little information about an audio driver (audio profile actually) product for PPC from AveLink: http://www.avelink.com/Bluetooth/Products/AudioDriver/index.htm
But they seem to integrate the MS Stack with two new profiles and the A2DP everybody is looking for!
I've been looking for a solution for... an eternity...
Anyhow can't find the product for purchase anywhere so I wrote them to see the features/price/etc... I'll let you know guys
Gee, hope is a strong feeling that leads us to keep trying... I can't even think on how much time I spent looking for this

TomTom Navigator voice prompts and phone calls

I have recently accuired the TomTom Navagator 2 software and am extremely pleased with it.
I do not currently have any car kit for making handsfree phone calls.
I have installed tha loud voice prompts so that the tomtom voice commands can be heard through the xda's speakers and im happy with this.
However compared to the loud voice prompts by the navigator software the handsfree audio available through the xdas speaker during a phone call is almost inaudiable over the road noise.
I therefore think im going to have to buy or build some handsfree.
My question is primarilly if im to use the car_audio_r and car _audio_l pins to output audio does all audio output through these pins or only phone audio. ie will i also hear the navigator voice prompts through my hands free (this is what i want)
Also Im wondering if it is possible to use the output from these pins to send audio to a car speaker without connecting an external mic and continueing to use the microfone built in to the xda during phone calls as know one has ever complained about not hearing me - i just cant hear them.
Thanks in advance for any help anyone can give - im sure somebody out there has played with this allready.

All audio (phone and PDA) is output on these pins.

As long as leave the CAR_ON# pin open (i.e. not connect it to ground or 5V), the microphone of the device is used.

Do you mean that internal microphone is used but all audio is still output to the car_audio_r and car _audio_l pins with the car_on# pin left open.

correct.

The soldering iron is warming up allready.

That sounds like exactly what i need - ill modify my tomtom cable to include the 2 new connectors then run an extra cable out of the 3 way connector on the tomtom lead to go to either my car stereo or a speaker amp mounted under the seat or something.
I dont know if my stereo in my car will except car phone input as its in the shop at the moment getting repaired so i cant take it out - but how do these things usually work - does a pin on the stereo side have to go +5 or GND for the car phone audio to replace the music or does it detect audio and automatically cut in over the music... excuse my ignorance car stereos and car kits are not in my realm of expertise.
If there is a pin that has to be made +5 or GND on steroes to know when the audio needs to be output can the xda handle this at all...

Usually car radios have a mute input to turn off or down the music when the phone needs the speakers. The XDA does not have such an output. You could fabricate something that detects audio and then for a preset time presents the right mute signal to the radio.
Always questions ask you do... Try and fail you must to learn!

Thanks for all your help. I'll start hacking at all my new kit as soon as possible...

can anyone help with wiring connections

Being a deaf old git (not totally but my hearing is not as good as I would like), I want to add a pair of apmlified speakers to the PDA so I can hear the voices in my Tom Tom on the Apline clearer since the socket is a 2.5 stero type plug does anyone know which is which on the connections please?

you should read this

I presume your referring to the Garmin 2.5mm to 3.5mm Jack Adaptor?
nice but not what I was really after
I have found a small set of speakers with a 3.5 jack on the end all that concerns me is the standard headset that comes with the IIi is headset and mic I presumed that a common return (usually the last outer connection and I imagine one of the terminals is for sound and one for mic if so it means only mono sound which is different to what I have been lead to believe just need to know which is the sound out connections on the plug so I can buy a 2.5 plug and wire them up.
The other thing I suppose is I could get a bluetooth headset if the sound from the Tom Tom comes over that but that is a unknown also

i was not talking about the post i made in that thread but more about the DIY stuff people were doing
more about the connector wiring here
http://wiki.xda-developers.com/index.php?pagename=Connectors

that would have been exactly what I wanted only thing it wasn't for the Apline unfortunately

Audio connections on himilaya and alpine are identical.

then one of us is wrong as the connections shown are on a FOUR pin connector my Alpine has a working THREE pin connector

not sure about alpine but i had no probs using my old wallaby headset and cradle on alpines sibling called himalaya

Well I seem to be a blind old git because I just noticed there is a inset on the plug and it is a four connection job sorry guys I only recently got given this thing and a quick glace it looks like three connections but one is inset behind the shield

The 2.5mm connector on BOTH Alpine & Himalaya can accomodate either a stereo or a 4-pin 2.5mm connector.
If the PDA detects a 4-pin plug inserted, it assumes the standard wired earphones and mic are connected, and bypasses the internal mic and routes stereo audio to the earphones.
When a normally-wired 2.5mm stereo plug (or adapter to 3.5mm socket) is connected to the PDA, it just outputs stereo audio.
I use a small 2.5mm stereo plug to 3.5mm socket adapter (having shaved away some plastic to enable it to fit, the socket is inset slightly) - to connect up a standard set of ipod-type speakers to the PDA, and it works a treat.
In short, either obtain a small adaptor to standard 3.5mm socket adaptor or if you get a 2.5mm stereo plug that fits nicely (Maplins, Radio Spares etc) and you want to solder it up yourself, it follows the same wiring cnventions as it's bigger 3.5mm brother, so a wiring diagram is just a google away.

[Q] External Mic for htc hd 2

Hi there. I hope someone will help me...Basically I need dictaphone for interviews so I bought "Olympus ME-52W Noise Canceling Microphone" and I tryied to use it with my htc hd 2. Phone is showing connected headphones but mic is not working. So my question is can I use external mic with my phone or is it related with software? If someone know the answere pls help me!!!!!!! btw I use Resco audio recorder

The problem is because the connector on the mic is probably the same as a mono headphone plug. The phone thinks that you have headphones plugged in. The phone has a socket that accepts 4 pole jack plugs. That is it requires a special plug that has contacts for both left and right audio as well as for the mic.
If you really want to use the mic I would go to somewhere like radio shack or mapplins and buy a 3.5 mm 4 pole jack plug and a couple of sockets. You could then wire up your own adapter to let you use the mic and also a pair of headphones or speakers at the same time. The pin out for the plug should be easy to find on the net and so long as you can solder I wouldn't see any problems.
Other than that plugging the mic directly into the phone will defiantly not work.

shut up stupid douche

Nexus6 hard-wired car dock help.

I am thinking of replacing the stereo in my car with a dock for my Nexus6. I was going to just buy a new head unit for Bluetooth connectivity and hands free calling on the road. Then i thought why spend money on adding a layer between me and my phone since i don't use my radio anyway.
I have seen lots of write ups and videos of how to replace your stereo with a tablet. But the one thing I have never seen anyone do is add hands free calling for their phone.
I am hoping someone can tell me how to wire a mic in to a USB cable as I also take audio out to run to an amp and power in back to the phone. I am aware I will not have fade control just balance and I am good with that.
I am aware that I will need to run the output to an amp and my Jeep has one from the factory. I am not worried about wiring in a converter to supply power and already have one that charges the phone while using gps and play music at the same time and a dedicated fused circuit activated by relay so there are no issues with battery drain. I will build a custom dock with a USB cable mounted in it in the dash in place of the removed stereo. I plan on using one of the wired mics you use with an aftermarket pioneer stereo mounted on the dash. The specs for it are Polar pattern: Omni directional Mic diameter's 9.7*4.5mm Sensitivity:-47dB+/-2dB Frequency Range: 20-20KHz Output Impedance: ≤2.2 kΩ SNR: >58dB Standard Operation Voltage: 4.5V Operation Voltage: 1.0V-10V.DC Wire Length: 4 M Ref Pioneer part no: CPM1064 CPM1084
What I need is someone to please show me how to splice the cable so I can add rca connectors to audio out, mic in, and power in and have it work. Or if that can't be done I can add a qi charger to the dock if I can wire the speaker out and mic in as a usb headset and make that work. Or if I need to add a signal booster to the mic input to make it work please say so and give me specs to go find one.
Thank you in advance for any help or useful suggestions.

A hard card case or soft case with a metal 1 cm below the M-logo. A neodymium magnet on the dashboard. No car kit needed. The speaker of the N6 is loud enough for use in a car for navigation and phone. Same with microphone.
Option is to use a phone jack converter to connect the N6 output to the radio.
An example how I used my N7 in the car.
http://forum.xda-developers.com/showthread.php?t=2137636/ - post #65
Note my N6 case has metal at the outside and below the M-logo, because behind the logo is a magnet sensor that switches off the screen.

Thank you, but I have children. I need to be able to play music, and their moms voice through the car speakers on long drives.
The car I prefer to drive is also noisy and my phone can't always hear me when it is in the dash mount.
What I want is just to make a wired connection to a mic, speakers, and power, through the micro USB port. So I get in the car, plug my phone in, and slide it into a permanent holder.
Money matters and this would be free, also convient since all my stereo did was get music and calls from my phone anyway.
I know how to wire in a Bluetooth reviever for the audio, and a qi charger so that would be wireless but I don't know how to get a mic input back to the phone, none of the premade affordable receivers I have seen have a mic input.
And I am aware I could take audio out and in from the 3.5 jack and either go wireless for the charging or have to plug in two cords in I get in the car.
I appreciate your help but I am looking for help to reach a specific solution that will be best for me.

I assumed already that you were looking for a custom and cheap solution, that's why I gave you mine. Just for the possibility you will get an idea.
About the microphone.
Wired headsets with earphones and microphone are normally connected to the 3,5-jack.
I think the mic-input-connector is there and not in the USB connector of the N6.
The N6 is not that different compared with other smartphones.
There are adapters available Google '3,5 inch headset adapter'

You are right in that there are dedicated connections already at the jack, and that they would be easy to just splice leads onto a standard wired headset to extend to where I want the leads to go. Even if i need to add a signal booster to the mic line.
My wife has a usb headset that works fine with my phone though so I know the capability is there, as with audio out on a usb connection to a stereo.
She wont let me cut up her headset to see what goes where though and it takes a while to get one from china. I was hoping someone knew so I could use what I have on hand rather than spending anything, I am cheap.
Thanks for your help, i have used my phone for music and handsfree when it's just me in the car on short hops. It does work fine for that and as a portable music player anywhere not to loud without any problems.
Once again thank you.
