The EarFun UA100 is a tiny beast of a DAC.

You might think the best route to optimal sound on your phone or laptop is a good pair of headphones. For some, that's enough. However, if you really want to kick the sound up to 11, you might need a bit of help.

One way to get a serious boost to your sound is with a digital-to-analogue converter (DAC). But good audio is not just about volume. You see, a DAC converts digital sound to analog, such that the signals can be understood by the human ear. The better the DAC, the better the sound. The problem is that a lot of phones and laptops don't include the best DACs.

So, if you truly want to get the most out of those brilliant headphones you've purchased, a DAC might be required. 

I was recently sent theEarFun UA100 DAC and tested it with two different wired headphones: the EarFun EH100, and the V-Moda Crossfade 3 -- and I came away impressed.
