Beyond Expectation ~ Superb piece of kit that brings recorded sound to life.

Great value for money. Lovely warm mid tone boost. I actually use mine with a tablet and my AKG 550s and Tidal. Funny wire/battery configuration. But it works well.

Bit underwhelmed to be honest after reading such great reviews. I'm using this with Denon D600 headphones via an iMac and I'd say the difference was very subtle rather than "massive" as some reviews I've read have said. Instruments do sound...Read more slightly better spaced but I feel vocals suffer compared to plugging my headphones straight into my iMac. Maybe it will grow on me or break in with more use but I am a bit disappointed overall. Maybe I'm missing something

Great little DAC, easy to connect with a little changing around on a macs audio set up. does the job at a good price.

This E10K just belies belief! For the price, I think this DAC/headphone amplifier is totally unbeatable. Yes, there ARE better-sounding units around, but you will have to spend at least double what this little beauty will set you back. It works seaml...Read moreessly with windows XP/7, is made to a very high standard and sounds great.
I use it to drive my Sennheiser MM 550-X passively to listen to both MP3/AAC and 24-bit 96Khz FLAC files via Foobar, and it's quiet, musical, and more than loud enough driving my Sennys. If you A-B this with an item like the Audioquest Dragonfly, then the more expensive item eclipses this with a slightly more refined sound, but as previously stated, this is more than double the price of the little Fiio.
Like other Fiio products, it really is a bargain, and I couldn't recommend this more highly. Get one now, before they realise they're almost giving them away at this price!

Value for money! This is a high quality product from Fiio, fast dispatch and delivery, good service and best of all, the best price on the market! Definitely worth a purchase!

So much better than the previous E10 that I bought two!
