Electronic Circuits and Projects Forum

My electronic skills are pretty much knowing how to solder and follow directions haha. But I'm wondering if there was something that would work like I have in the picture It would use the electrical signal to tell the LEDs to light up on an external power source, like a small battery of some sort.

It looks as if you have plenty of room for the circuit that Colin posted. All it is is a couple transistors and a few resistors. You'd need to use a small battery, like a coin cell. Doesn't look like enough room for AAAs.

By the way, your picture is waaaaaaaay too big. Be nice and resize!

I don't know what that circuit board inside your headphone is, but all you need to do is connect his circuit to the wires coming into the headphone. Just find where they connect to that circuit board, and solder wires to those connections. (The incoming wire to the headphone, not the wire to the headphone speaker element.)

Out-of-phase speakers cancel bass frequencies. Hi-Fi stores ALWAYS had the speakers connected out-of-phase then the bass tone control was turned up to maximum to try to make some bass. I always re-wired them properly and turned down the bass tone control to normal.

Close out-of-phase speakers and headphones feel like your head is wider than normal. In-phase feels like the sounds come from inside your head.
