How to use standard headphones?

[bighill89]

I want to use standard headphones (ie iPod headphones) with my HTC Magic. I ordered a miniUSB to 3.5mm adapter from eBay but when I plugged in my headphones, it didn't seem to fit well. My headphones went in and made a clicking sound at the very end. No sound came out of the headphones. I tried several types of headphones and still no dice. The proprietary headphones that shipped with the phone work. I doubt the adapter is defective because I ordered two, and the same thing happened to both.

So what kind of adapter do I need? I'm thinking maybe a miniUSB to 2.5mm? I'm so confused. Please help!

So 3.5mm is what I need? What is 2.5mm used for then?

But why should it matter if it's for Motorola or HTC? It's standard mini USB to standard 3.5mm, no? Guess it does matter?

I saw that it was for Motorola but I didn't think it mattered. I thought it was standard mini USB to standard 3.5mm? Guess it does matter?

Could be a proprietary pin-out like Apple.

anything to make a quick buck off the consumers

no the htc headphone adaptor has extra pins for the headphones, you can use a standard usb to connect a computer and charge though.

In case someone still needs this:

The correct adapter needed is an "Enhanced Mini USB" ( or EMU) to 3.5mm. EMU is rectangular with one corner angled off, and it's small enough to fit in a standard mini usb port.

Though a standard mini usb cable will charge the G1 (or other EMU device) and allow data exchange with a computer, the enhanced version has additional pins for stereo headphones out and mic in. Don't bother trying to hack a 3.5mm jack onto an "EMU to USB-A" cable. It will likely not have those extra pins attached (since audio exchange is not the purpose of the wire).

It's not a proprietary jack, but HTC and Motorola seem to be the only advocates. My G1 shipped with a short adapter cable allowing the use of normal headphones. It's pretty lame to ship such a device without one. HTC has since learned to just include a 3.5mm jack on their phones, after much public outcry I'm sure.

The Motorala/HTC pinouts are likely the same, if not you could split the wire in the middle, cross the appropriate wires and heat shrink it back together. I just saw a Motorola cable on Amazon for $1.39:

Best of luck.
