This is the perfect thing to provide the extra energy needed to power larger speakers with a portable audio device without severely draining battery power. This pocket amp also allows for louder audio through headphones or small speakers. Time to blow out those voice coils!
Step 1: Hunt and gather supplies
-A small hearing amplifier, often called a personal amplifier or advertised as spy hearing (I used a
Radioshack brand "amplified listener" )
- Stereo headphone cable with 1/8" jack
-2X AAA batteries (or whatever your particular model requires)
-Connecting wire, scrap wire
-Hot glue, silicone or epoxy
-Drill and bit slightly larger than the the width of your headphone cable
-Audio source and headphones to check your progress.
Step 2: Void the warranty
Step 3: Check the microphones
Step 4: Identiy your connections
Step 5: Wire the connections
Here some of the wires attached to the board were too short, so I used a piece of scrap wire (yellow) to connect them.
