DIY Headphone Amplifier – upgrade those cheapo headphones to sound great


This DIY CMoy Headphone Amplifier works out at under $20.00. Buying a commercial model would cost between $100 and $200. You do the math, Matt. Sure, you’re going to need some tools, a little electronic ambition and a liking for electrolytic capacitors, but what the heck…live a little.

 This is a somewhat technical project. You won’t need to understand how the amp or its components work, but you will have to be able to follow some pretty exacting directions. If you build it incorrectly, it can take hours or even days of troubleshooting to find the problem. Yet, the CMoy is a good choice for beginners because this amp and variants of it have probably been built by thousands of people over the years.
