I picked up this relatively inexpensive Bluetooth device on Amazon recently, and while it functions very well, I was finding that the over-ear speakers let in too much air noise when on the freeway. So, I’m planning on replacing the speakers with some in-ear buds, or maybe just a female 1/8″ audio jack, so I can switch headphones when I would like. As in any hack / mod, it’s best to start by doing your research. I could tear the current headset apart, but I wanted to see what I could learn first without ruining anything. Because I wasn’t able to find any photos of the internals of this device, so I have taken the photos myself, in hope that they help someone else.
