Good Value

I had used the FiiO for years and bought this one as a replacement. Works well with the added volume I need for headphone use. So far, so good with this unit, and very small and portable to use (and lose) so keep an eye on it when traveling.

These little guys are awesome!

I wish Sonic was carrying these when I bought mine. I have two of these which I use to amplify the the headphone-jack output of an mp3 player going thru an 3.5mm-to-RCA Y-connector into the RCA input of a car amplifier (mp3 mounted on handlebar of a MoTo going to a car amp). Especially if you have to branch the two outputs further into 4 outputs for a 4-channel amp, because doing so further halves the voltage. The battery-life on these things is friggin' great. I'll forget about charging it for a long darn time until one day it shuts-off, and I go "Oops!". They seem to stay charged for quite a long time during periods of no use as well.

mp3 to shark mc

This item worked unbelievably well for a while, I was the envy of
riders with systems costing six times as much as mine!
Then it quit working.I dont know if I just got a bad one or what.

pretty good

When ordering I originally had little expectations for this amp. Cheap price, small unit, how powerful could it be? The unit is built fairly solid. Also I have tested this on several over the ear, in ear, and just all around different situations like multiple outputs. Overall for the price this is a very good value. Under certain situations like spliting to 2 or more unit did it really have an impact on loudless. With thatbeing said the amp cleans up output greatly. For audiophiles like me this is great! The rechargeable battery lasts quite some time on a single charge. Overall yes I would definitely recommend this amp over more expensive units because of the price vs quality. This tiny unit will greatly clean up output while upping output a tad.
