Like most phones these days my Cingular 3125 (aka, HTC StarTrek, aka QTek 8500) uses a combined headphone/charging port preventing the use of regular 3.5mm headphones.
What’s less common is that it’s impossible to get a simple headphone adapter for it. The only adapters I can find have an 80cm long cable ending in a combined volume control/3.5mm socket. When you add in the length of your regular headphones that’s a serious amount of cable!
The 3125 is a pretty decent media player and great for places like the gym. I decided to I’d take the headphones that came with the phone and perform a little surgery to make my own compact adapter
Requirements;
- A 3.5mm Jack from Radio Shack (~$2)
- A soldering iron and basic skills
- Fine wire strippers
- A set of helping hands
- Patience
A day later I’m
