[Q] Helmet Handsfree Wiring - Nexus One - Plz enlighten me

Hello,
I read this forum for quite a long time but never had a chance to register or post. Please forgive me for coming in with questions.
Okay... I want to connect my Nexus One to my Nolan N-Com Basic Kit, but I can't find a suitable ready-made cable for that.
And then I:
Bought two BlackBerry handsfree (Chinese made - $3.42 each)
Cut them below the microphone/button part
Connect the four cables in it
Pictures speak better than words:

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Okay, and now here's the problem:
If the cables are just separated like that, the sound is weird, low, and ugly
If I short Red and Green : Pause/Play/Ffw/Rew*
If I short Red and Blue : Pause/Play/Ffw/Rew*
If I short Red and Yellow : Pause/Play/Ffw/Rew*
If I short Green and Blue : Dead - No sound
If I short Green and Yellow : Sound's OK, loud enough, but still a bit weird (like either left/right channel is gone/low although both of the speakers works).
If I short Blue and Yellow : Sound's OK, loud enough, but still a bit weird (like either left/right channel is gone/low although both of the speakers works).
* Pause/Play/Ffw/Rew means sometimes it pause/play/fwd/rev the song, can't understand why, and sometimes it's also reboot the phone
I'm now using the Green and Yellow short, because it's the one that sounds better on most songs.
My first question:
What to do to at least make the sound alright? I crack open and look at the original BlackBerry wiring but got confused. There're R-G-B-Y cables going to the button/mic casing (the cables that I use), and then there're G-B-Y-Y going out from the button/mic casing to the earphones.
My second question:
I really want to have the original (Nexus One) handsfree's functionalities. Having buttons in the cable to receive/hangup phone calls and to play/pause/rew/ffw songs. Is there a wiring diagram for Nexus One's Handsfree somewhere?
Thank you.

I have a similar Problem, I bought a 4-pin 3.5 cable, which works perfect with the Computer, but not with my Nexus One. There is sound, but its horrible...
Do you got a solution for your Problems?

Hi,
Yes I ask a guy in a local electronics workshop to do the work for me based on the attached diagram in this post.
hackaday dot com/2010/11/03/patching-into-android-music-control/
So it needs some resistors, switch, etc., which is beyond my expertise.
Good luck!
ps: sorry for the new-user-spam-prevention workaround

I'm not familiar with your hardware but you may have the speakers grounded through the mic+ wire. Is there a screen on your cable? That might be the real 0v connection.

Your description of the wiring suggests to me that:
G and B are left and right speaker+
Y is 0v
R is mic+
HTH.

Like happy jack said, it looks like the green and blue are left and right (+)
Red is mic +
and "Yellow"(looks like copper) is ground (-)
If the cables are just separated like that, the sound is weird, low, and ugly

It probably is because the pin configuration is different in the nexus one and the helmet.
Try to do this:
If that doesnt work, then you need to do something more advance that I dont know about.
If you want to just make the speakers work, you could just buy an stereo extension (plug with 3 pins to plug with 3 pins), or try to do this:
Solder both the red and yellow cable or just the yellow and dont solder the red one.

Hey guys, thanks for the replies, but I have the problem solved a few months ago by asking a technician to do the work for me based on the attached diagram.
I got the diagram from some blogs. Link is on my previous post, and here's another one:
wisebread [dot] com/build-a-cable-to-control-your-android-phone-while-you-drive
And although the diagram is for a TRS to TRRS conector, it's sufficient for the technician to create a connector cable that basically works like the original N1 handsfree, but without the microphone (because the micropone line is passed along the whole cable to be used by the helmet's microphone).

I got it.
As sotodefonk mentioned, N-Com and the Nexus One have different pin configurations. With the Information from yofazza, I was able to figure out which cables have to be crossed. Now the Sound is good, and the mic works!
Thank you guys!

bluetooth speaker recommendations

i've been searching for a decent home solution for bluetooth/smartphone integration into a pretty simple hifi/multimedia setup (media pc feeding 5.1 speakers & tv through s-video).
there seems to be an abundance of low-end portable speaker solutions and the beautiful zikmu from parrot/s+arck which are around a grand (uk £1,000). ouch!
does anyone know of a bluetooth receiver with a 3.5mm jack-out or similar standard audio connects to supply a domestic amp/speaker system through aux-in?
the belkin bluetooth music receiver (just found) appears to fit the bill ... has anyone any experience with this topic? thoughts welcome - especially product recommendations & those to avoid!
thanks & apologies for not posting links to specific products but i'm not allowed as a noob

I have a Jawbone Jambox at work (I sell them actually, but we have one open for display).
I tried it today and it's amazing! A bit costly, but worth every cent. Great sound quality, great design (a given with Jawbone), and has a 3.5mm jack (though I think it's an input, not an output).
Some links for reference:

yes, i'm aware of the jambox but it looks rather small physically but all reviews state how powerful it is ... so, it'll need a demo before parting with the cash. i haven't seen a single poor review, which says something in itself i guess? & yes, the jack soclet is for non-bluetooth input.

Try it, you'll be amazed.

I was looking at the Jambox when I was researching BT speakers for myself... it was in my top 3 choices... but it was just so expensive. I ended up getting a Creative D100, which from the research I did, seemed to be the best for their price. They're a lot cheaper than the Jambox.
I have to say, I was amazed by how nice they sounded for their size. They aren't as portable as the jambox, but I'm happy with them.
They take AA batteries instead of a built-in lithium battery, which I prefer for a speaker that I hope will last several years, as lithium batteries start dying after 300 or so charges, and with AA batteries, it's easy to replace when they die.
It also can run off AC power, and has an aux in port to use with devices that don't have bluetooth.
Overall, I am very happy with the D100.

thx all, zarathustrax's suggestion does look a good affordable-portable solution but i'm primarily looking for a bluetooth feed into an existing hi-fi setup along the lines of the Belkin receiver mentioned initially.

You can always get one of those bluetooth "clips" that has a regular stereo audio-jack for speakers or headphones. It would do the same thing as the belkin receiver, but you can also use it for a handsfree headset for your phone and use it with stereo headphones. I've been looking at this one for a while... it has good reviews, and has a screen that shows caller id and song info (I think), and you can call people back directly from it without getting your phone out or control your music.... http://www.amazon.com/Sonorix-Bluet...phones/dp/B000V1UGZ2/ref=cm_cr_pr_product_top
It's about the same price as the Belkin receiver and you can use it for a lot more.
That's my only suggestion for a receiver, but I've never used it, but it has a lot of good reviews on amazon. I'm not sure how it would compare to the Belkin receiver, but you can use it for a lot more.

I have the Sony Ericsson MBS200 and I'm pretty happy with out. It has lineout if you prefer to output it to a bigger more powerful speaker. It's also pretty cheap and sounds really good. And it runs in recharchable battery.

support for car

Any suggestions where to buy a good support for car specific for i5800?

This cheap universal holder does well in portrait mode. I use the air vent mount, it is pretty robust.

dont know about car specific, i bought one similar to the above post from media-markt, rotates to landscape view etc, any smartphone holder should do the trick, havent seen any with a dock function yet..... although its just a mini-usb connection, maybe someone out there has made one?

I bought a standard microUSB car charger for ~5€, that does the trick fair enough without any harm. With this baby even the sound is better than the built-in speaker :-D The whole bunch was far below 20€.

Hi blacky, live near the border between B, NL and D (drie landen punt), and yep originally from scotland!
mobistar was the only sender with a mast here, border is only a few km's, otherwise it switches to a NL provider and the roaming charges start building up

My car could legally drink alcohol almost anywhere in the world :-D Nobody would bother stealing an old cassette unit from an old car (I hope), and the sound is great, so no reason for me to replace.

seen the picture of the cassette and the pencil doing the rounds on fb? tripped over a box in the attic filled with tapes not long ago....
were going waaaaaay off topic now!......

I found a decent one
here: http://www.londonmagicstore.co.uk/C...%2526+Charger+for+Samsung+Galaxy+3+i5800.html

looks okay, price is good including charger, but looks like a universal holder, wouldnt say it was specifically for the SG3....

idd
but I don't think they ever gonna make a specific car holder for a "low" end device like ours

My dad bought a in car holder that sticks to windscreen and the phone clips in snug . Only thing is that it's for his Nokia 5500 but I tried my galaxy 3 in and it was a perfect fit. Unbelievable but true

[Review] Syllable D700 Bluetooth headphones for 20$

Hey,
some days ago Syllable sent me a pair of their D700 bluetooth in-ear headphones for review so here it is now
Let me first clarify that I am neither paid by them nor related to them in any other way.
Let's start :highfive:
General information​
The headphones ship in a small box with them printed onto it:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After opening it up one can see the headphones, a charging connector that is rather short but long enough if you ask me and ear plugs in different sizes:
The medium ear plugs are already attached to the speakers, a smaller and a bigger pair ships with them. I had to go for the smaller onces as my ears are quite small. This was definitely a big plus for me!
The headphones have three buttons as you can see here:
The key mapping is
Volume+/Next Song
Pause/Shutdown or switch on
Volume-/Previous Song
The first element in the list corresponds to a short press whereas the second element is a long press.
The buttons have a good haptic feedback in my point of view! There is also a microphone built in which really surprised me keeping in mind that these things cost just 20$! If you receive a call while wearing them a single press on the middle button answers it. If you then press again the call is hung it.
I collected the following results while running a 15km run:
Pairing​I used an Elephone Trunk and an Elephone P8000 as a pairing device and both worked fine with the headphones. To pair you simply have to press and hold the middle button until the speakers turn themselves on. A built in LED then starts to blink blue and the "D700" can be found in your BT smartphone menu. Only one device can be paired at a time so if you switch devices, you have to turn off bluetooth on the first device in order to pair the second one. I think that's reasonable as also only one person can listen to the music coming out of these headphones so there is no need to pair more than one device at a time.
Sound Quality​The sound quality is okay for me. I usually wear on ear headphones which have a lot of bass - obviously the D700 have less bass and more mids and highs. When I pushed a bit onto the earphones the bass became more present but that is nothing I want to do while running. I still like the sound quality given the low price and the fact that these things have tiny speakers compared to my big headphones. These highs help to understand a calling partner though if making a call. Also I have to note that the built in microphone seems to be good as well because my partner did not have any problems understanding me.
Battery Life​The D700 came pre-charged and without further ado I literally hit the ground running and tested them. Surprisingly the battery lasted the whole 1.5 hours run! The box states 5 hours music time and I ran another two 1.5 hour runs after charging the device's battery via micro USB, so I'd say that's more than enough if you go running. If you want to use these things for daily music I am pretty sure that you won't make it through the whole day if you listen to music all the time. But I wouldn't recommend that anyways because of the...
Design​The design of the D700 is not exactly subtle. My pair came in a neon yellow color and I am pretty sure the designers aimed rather at runners than at businessmen. The headphones are not exactly ugly but I personally would not wear them other than for running or sports in general.
Conclusion​After all I am rather impressed by these inexpensive headphones! You basically get a full functional bluetooth headphone pair with built in microphone, calling feature, music adjustment buttons and a decent battery life for just 20$! Also the bluetooth range is really great! After running I walked into a different room while having my phone lying on the desk and there were no connection problems at all.
The only downside I can on the D700 spot is the extroverted color.
Pro:
Cheap - 20$!
Good sound quality!
Good battery life!
Calling feature!
Great BT range!
Comes with three pairs of earplugs!
Good fit!
Con:
Color
If you're looking for a cheap pair of wireless headphones for doings sports, go for these guys! You won't be disappointed. :highfive:

[Review] Syllable D300 Bluetooth headphones for 12$!

Hey,
some days ago Syllable sent me a pair of their D300 bluetooth in-ear headphones for review so here it is now
Let me first clarify that I am neither paid by them nor related to them in any other way.
Let's start :highfive:

}
The medium ear plugs are already attached to the speakers, a smaller and a bigger pair ships with them (bigger is not in picture). I really like the little clamp that comes with them so I can attach them to my shirt. Big plus!
The headphones have three buttons as you can see here:
The key mapping is
Volume+/Next Song
Shutdown or switch on/Pause
Volume-/Previous Song
The first element in the list corresponds to a long press whereas the second element is a normal/short press. This is quite counterintuitive given that the buttons have + and - printed on itself. Once you figure that out it is easy to use though The buttons are also a bit sluggish to press but they are still usable. There is also a microphone built in which really surprised me keeping in mind that these things cost just 12$! The call quality is mediocre though. If you receive a call while wearing them a single press on the middle button answers it. If you then press again the call is hung it.
Pairing​I used a Blackview Alife P1 Pro and an Elephone P8000 as a pairing device and both worked fine with the headphones. To pair you simply have to press and hold the middle button until the speakers turn themselves on. Then keep holding the button until the built in LED starts to alter between blue and red. The "D300" can then be found in your BT smartphone menu. Only one device can be paired at a time so if you switch devices, you have to turn off bluetooth on the first device in order to pair the second one. I think that's reasonable as also only one person can listen to the music coming out of these headphones so there is no need to pair more than one device at a time. If you wanna use it after pairing again a short power button press is sufficient so you don't have to hold the button longer than 1 second when starting the phones the next time.
Sound Quality​The sound quality is good! I usually wear on ear headphones which have a lot of bass - obviously the D300 have less bass and more mids and highs. When I pushed a bit onto the earphones the bass became more present but that is nothing I want to do while running. I still like the sound quality given the low price and the fact that these things have tiny speakers compared to my big headphones. They also have better bass compared to D700 which I reviewed here.
Battery Life​The D300 came pre-charged and I tested them immediately. The box states 4 hours music time which is a realistic value. After charging the device's battery via micro USB, you get 3.5-4 hours out of them.
Design​The design of the D300 is rather extroverted. My pair came in a neon blue color and I am pretty sure the designers aimed rather at runners than at businessmen. The headphones are not ugly but I personally would not wear them other than for sports or when being at home.
Conclusion​After all I am rather impressed by these inexpensive headphones! You basically get a full functional bluetooth headphone pair with built in microphone, calling feature, music adjustment buttons and a decent battery life for just 12$! Also the bluetooth range is good! The only downside I can on the D300 spot is the extreme color.
Pro:
Cheap - 12$!
Good sound quality!
Decent battery life!
Calling feature!
Great BT range!
Comes with three pairs of earplugs!
Good fit!
Con:

If you're looking for a cheap pair of wireless headphones for doings sports, go for these guys! You won't be disappointed. :highfive: I definitely recommend to buy them because of the low price and good features! I would also prefer them over the D700 but that is my personal opinion.
