This product is great except for one thing. the notch is on the wrong side, so you have to break out a precision knife to make it close properly.

Same problem here. I'd recommend getting the breakout-less version. I don't think the pins are too small to hand solder but a comment posted on the other part lead me to order this instead. I think I'll just remove the breakout. I wonder if the pin numbers match up correctly.

Too bad companies like htc, sony and others think they know whats best for their consumers amd use proprietary cables, media, and drm. Glad we have sparkfun around to save us. When you guys call PodGizmo about this issue, tell em to drop the price too ;-)

Yeah, it's a big shame that the breakout board is wrong way around. It ends up being quite useless, $7 difference for a board you have to cut anyway...

The pin outs are slightly different on my g1. It appears that pin 7 (labeled AG) is supposed to be analog ground (for mic + audio). When pin 8 (labeled CK) is connected to any ground (pin 5, 7, or 12), audio output is enabled. I believe the labels may point to this, with AG being Audio Ground and CK being Check? I'm still trying to figure out the behavior of pin 9. I can only get it to control the music player. Short press (connection to ground) causes audio to play/pause while long press brings the music app to the foreground.

Pin 4 is used to detect the presence of the wall charger. If you connect that through to the unused port of a mini usb plug, and then plug in the wall adapter, your phone will be able to charge at a faster rate. The usb plug coming out of the wall adapter ties that pin to ground so the phone knows it's safe to pull more current than the usb spec allows.

I can confirm that the breakout board is definitely inverted from what it should be; the slice out of the board should be on the opposite side.

It's not as big of a deal as made out to be above, though; instead of carving the breakout board, simply notch the "keyed" side of the housing out so that the square side fits in it with an sharp knife. Space-age ABS plastics fear my leatherman of doom. :) You have to open it up a little bit on the inside as well; the board slightly interferes with the wire keeper closest to the plug.

You can get away with this because the internal keying of the connector itself is identical on both top and bottom, so once you open up the external key, the connector slips right into place, and you can close the housing.

The caveat, of course, is that your plug now aims left instead of right. As it turns out, that's exactly what I wanted for my application, but YMMV.

Just a quick note about the pinout: here's a fairly complete schematic for the headset, thanks to a fellow on xda-developers.com who tore his apart and documented it. Make careful note of the pinout differences from what's listed in this item's description, however!

Is there any plan to fix the problem with reversal of the board contours that have been mentioned in the comments, or is it going to stay as-is, requiring modification to fit into the housing correctly?
