    Detailed and punchy sound
  

*by S***Y on Reviewed in the United States on July 19, 2011*

This is a nice example of a super minimalist (and cheap) product that does its job very well.My original reason for getting it was to allow me to drive two sets of headphones from a netbook while travelling. However I now find I'm using it for solo listening as well. My primary player is a Sony NWZ-S639F which I consider to have a very good output stage but there is a marginal improvement using the Fiio in terms of overall detail and texture and bass definition. The sound is a bit more relaxed - it's obviously not straining to drive my Sony V6 phones at lowish volumes. Subjectively the frequency response seems quite neutral; it certainly doesn't introduce any high frequency harshness which I am quite sensitive to.Using a 2G iPod Shuffle as the source the improvement is more obvious. This player seems to have an underpowered output with poor bass extension and mid-upper harshness. Big improvement when playing via the Fiio.Is it perfect? Certainly not. It's a bit plasticky and the "power on" LED is too close to the headphone output to be visible when a full size headphone jack is plugged in. And if you turn up the volume you can hear vocals and instruments distorting a bit during bass-heavy passages (probably a limitation of the power supply rather than the very good op-amp they are using) This is really not a problem at the volume levels I find comfortable for extended listening, and it's really remarkable how much of a punch they have been able to extract from a single AAA. With other headphones or if you want or need to deliver higher power, you would probably want to go to something with a beefier power supply.UPDATE FOR HACKERS ONLY: I decided to try running the E3 from a pair of rechargeable AA's because with a single AAA the voltage is very close to the 1.4V rated minimum for the chip they use (LM4917). I could have gone higher with a 3.6V lithium but this was quick and easy...... _*WOW*_  This thing really sings now. I think I will pop it out of its plastic housing and build it into a mint tin. It really is a different class of sound. I'm hearing stuff I didn't know was there and I can turn it up without it sounding 'loud'. Hard to describe but I'm really impressed. Think I'll buy some more of these.

    Works well for $9, but some design flaws.
  

*by S***H on Reviewed in the United States on April 1, 2013*

Let me start off by saying this is well worth the $9 I played for it. It definently increases over all volume substantially, but that isn't why I bought it. I bought it because I purchased a set of cans, just budget pair, and realized the internal amps in my devices wouldn't be able to power them fully. Coming from a background in radio communications, I know a little about amplifiers. Basically an amp can be underpowered for a set of speakers yet still produce a listenable volume, but sound quality will suffer because there won't be enough power to hit the highs and lows, and overall the sound will be muddy and indistinct. That's because the signal sent to the speaker is a wave, not constant, and a sound of high amplitude will be clipped when the amp maxes out. That's what this little black box does, it amplifies the signal coming from your internal amp at a set gain, helping to prevent either amp from maxing out, so you can drive big cans, aka headfones. When it comes to headphones, generally the larger the driver, the better.Pros:Sound is crisper and more defined across entire rangeBass hits harder without becoming muddy or seeping into other rangesTiny, I didn't realize from the picture just how small it is, it is slightly larger than my thumbSupposedly 10hr battery life, this remains to be provenNeutral:Uses AAA batteries, this as advantages and disadvantagesDoes not come with headphone splitter in the pictureCons:No off switch, to turn off you must unplug the headphones.No pocket clip, though it is small enough to be just left hanging.Slight hiss, this is to be expected, anytime you introduce a new component or connection into a transmission line, you increase the riskof interference. Plus I'm using low impedince/high sensativety earbuds while waiting for my headphones. The amp may amplify the interference just enough for the ear buds to turn it into sound. Only noticable when no music is playing.I will edit my review once my headphones arrive. Plus, I plan to try to get this open to add switch and possibly solder the input audio cable directly to the board to cut down on interference.

    Fiio E3 Headphone Amplifier
  

*by A***E on Reviewed in Canada on November 1, 2012*

The amplifier turns ON as the earphone is plugged. Also turns ON a light on the amplifier. The bettery is discharged by the light  as it stays ON as long as the earphones are plugged in. Disapointed, I do not use it anymore.
