Two TRS to TRRS minijack adaptor?

Thread Starter 

I have a Blackberry phone which uses the fairly standard four-contact 3.5 mm TRRS minijack setup to connect its phones-mic-and-button headset. The headset that came with the phone was absolute rubbish, so i bought a NuForce NE-7M (after careful reading of the Head-Fi forums, of course), which has a suitable four-contact jack, and rapidly became a happy man.

 

I also have a laptop (an Asus EeePC 1001HA) which has the usual pair of 3.5 mm TRS minijack sockets for output to headphones and input from a mic. I can plug the NE-7Ms into one or the other socket, but of course, not into both at once. I haven't actually tried using the mic socket, but when i use the phones as phones, the connection isn't great: if i push the jack all the way in, i only get sound in my left ear. I can pull it out a couple of millimetres, where it sits stably, and then i get stereo.

 

What i'd like is a small adaptor which has a female TRRS socket and two male TRS minijacks on short leads, into which i could plug my phones, and which i could then plug into the laptop, thus properly connecting the headphone output to the headphone paths in the headset, and the mic input to the mic paths. Does such a thing exist? Where can i get one? Where, in general, is a good place to look for something like this (i'm in the UK, but visit the US every so often)? I tried Maplin's website, and found nothing.

 

Thanks,

tom

I need one of these too!

I've seen the inverse of this--allowing one to plug a mic and headphones/speakers into a single 3.5 TRRS male.

Any help would be appreciated!

Hey,

 

where did you find a plug that allows one to plug a TRS mic and TRS headphone into a single 3.5 TRRS ?

I could of course make one, but I want a single small plastic piece that do this for me.

 

Br,

Simon

Assembled adapter:

Mini TRRS cable jack:

The adapter seems to be a custom built thing and is currently not in stock. But it's really just a jack wired to two Neutrik mini plugs. Shouldn't be too hard to DIY if you know which iPhone TRRS channel goes where. Except maybe 6 wires in that tight space can be tricky to solder. Maybe combine the ground channels from the two mini plugs before entering the jack.

The first kvconnection item Yoga Flame posted is exactly what i need. As is this:

And it's half the price. Ideally, it'd be something a bit more compact, since i don't need six inches of cable flopping around, but either of those designs would do.

 

I hear that the Dell Mini netbooks have native TRRS connectors, which is cool. I hope that becomes standard.
