Assemble a switch box to switch from listening to music on head phones to listening to answering your phone with your left ear, while music continues in the right.

(requires some electronic components, and basic soldiering skills)

Step 1: Explanation:

Hokai, so I was getting tired of having to take off my head phones when having to take a call, and I was wishing I could listen to music while on hold or on a boring call.

So the idea was born and after a quick trip to my local electronics store, so was the final product.
i know nothing in soldering... but a bit curious... wanna make a spliter for sharing music... where can i buy two 3.5mm audio jacks? from my circuit knowledge in physics class... do o just solder two jacks in paralled to a 3.5 plug head? and how much does it cost to buy audio jack with decent listening quality? also can it handle surround sound or will it be mono? sorry to ask such a long question...
What would you recommend doing if the headphones already have a mic?
<p>Depends on how the mic is attached.</p><p>What mic plug comes out of the headphones? Regular mono 1/8&quot;? Or is it combined into one plug like a hands free headset?</p>
brilliant i ra across this along time ago and have been trying to find it ever since. i just modded my helmet to let me put some speaker elements out of a pair of headphones from the 70s and im thinking ill add a mike and run it all to a pocket on my jacket
this idea is genius!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
WHERE DID YOU GET THE SOUR TOIDS GUM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Since all your grounds are hooked together anyway, couldn't you just use a SPDT switch instead of DPDT?
Not sure. I think technically, yes, but I haven't tested that, nor do I understand the full impact of doing it. I'm of the mind that there should be as few things connected to eachother as possible. But if you try it out (or I test it out) let me know, and I'll update the instructions.
you can.
I have been trying to find a plan on how to make something like this for my desk phone. Apparently the technology isn't as nice and compatible as it is between a cell phone headset and a pc/music headset. Does anyone know if this would work if I added an input like the one on my desk phone headset, and how the cables would be set up?
Your best bet would be to take apart or otherwise discover the connections on the headset, and splice the wires together accordingly. I actually have a plan in the works for one of these for my work phone using the rj11 connector and my quality headphones and a mic attachment.
I hope you make an instructable when you execute the plan that is in the works :-)
seems like a good idea to make a line in into a mic to record music clearly.

I can hack together an in-line music volume control, but don't want to have to mess with housing. Time to hit the 99 cent store again, and see if they've got a mic/volume control hands-free...
neat i quite like is too bad i have to get a bluetooth ear peice as a slight mod for earbud users: have one ear be used for a mic tho one would have to pull one earpeice out and hold it as a mic tho depending on the sencitivity it ma be able to be clipped to a collar??
Do-able!! Though the original idea was to be able to use your better headphones, you could hack together some headphones and a phone earpiece so one headphone wire could use one of those in-line mics, you'd just have to split off the leads, and probably make your own 3.5mm stereo jack, and mic jack as well.
The blue is always audio. However on the AUX, the blue is the left audio, and red is right audio. On the phone jack, the blue is the speaker, and the red goes to the mic.
one more (noob) question, in your diagram the green is ground, then what are the red and blue wires. thanks
Updated some pictures, added clearer diagram
Good idea, I've been planning on something similar. Another comment, maybe closer up photos? Under topology most of the picture is the background, hard to see actual layout (by design?). Thanks.
Unfortunately there isn't much to see on that topology picture, only a mess of wires and some electrical tape seperating some soldiering points on the jacks. The topology I've layed out is just a recommendation, your topology is really dependent on how you want the final product to look. However if you're still interested I've posted the whole image (2304x1728) here: <a rel="nofollow" href="http://tinyurl.com/jqd77">http://tinyurl.com/jqd77</a><br/>
yep, I&quot;ll bust something out in paint... =)<br/>
Hey, great plan/idea, would it be possible for you to make a clearer diagram so I can see what is what. Thanks
