You're welcome. It's easier than building a custom amplifier, and it was designed for the right signal input levels. Some of the PC speakers that I've scrapped had a 220 ohm resistor in series with each earpiece when using headphones.

You can buy small headphone amp boards on Ebay, but most are overpriced.
