Headphone Amplifier Specifications

Amplifier Style
Some headphone amplifiers are designed to be portable and others are meant to be placed on a desk. This will tell you what style of amplifier this item is.
Portable
Digital-to-Analog Converter (DAC)
A Digital-to-Analog converter (also known as a DAC) converts a digital audio signal into an analog signal. This is especially helpful for listen to music from digital sources, such as iPods and smart phones.
No
Frequency Response
The range of frequencies the amplifier will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
10 - 100000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
<0.009%
Input Connection
This is the manner in which the headphone amplifiers receive an input audio signal.
3.5mm Mini-Jack
Input Impedance
This is the input impedance of the headphone amplifier.
16-300 ohms
Output Connection
This is the manner in which the headphone amplifier will output the audio signal.
3.5mm Mini-Jack
Number of Outputs
Some headphone amplifiers have a built-in splitter so multiple pairs of headphones can be connected to it. The number specified here is the number of headphones that can be connected to the amplifier.
1
Output Power
This is the output wattage of the headphone amplifier. It is measured in mW.
300 mW
Output Impedance
This is the output impedance of the headphone amplifier.
16 ohms

DAC Specifications

Maximum Output Voltage
This is the maximum voltage that the amplifier or preamplifier is able to output.
Output Impedance
This is the amount of impedance that the microphone allows.
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
<0.009%
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
Crosstalk
Crosstalk is defined as the unwanted transfer of signals across communication channels. The higher this number is, in dB, the better crosstalk rejection the DAC is capable of.
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
Digital Inputs
The type of digital inputs the digital-to-analog converter features.
Jitter
Jitter is a deviation in or displacement of the pulses in a high-frequency digital signal.
Line Level Outputs
The type of analog line level outputs the DAC features.

Great little amp/Great customer service

February 6, 2013

I receievd a set of Logitech UE 6000 headphones (fantastic by the way!) as a Christmas gift and wanted to upgrade my power source from a current Fii0 E5 amp. The difference between the E5 > E11 is night and day!! I use the amp on lower power setting and flat gains/EQ and my headphones sound awesome. Imagine my dismay when 16 days after having the E11, the jack input lost grip, causing static/loss of power. i find this to be a quirk as my E5's still work great after 5 plus years of 6 day/week use. Good news is the time frame from calling Sonic to getting a new E11 amp was 6 days!! Great customer service.. I would highly recommend this amp and this company to buy it from.. * My durability rating is from the defect but I really anticipate years of trouble free use. The unit comes with (2) silicone bands for wrapping to music source but one could be smaller for wrapping to a IPod.*

AN ENHANCMENT.

April 19, 2014

THERE ARE TWO ESSENTIALS AND IMPORTANT THINGS THAT WE NEED FOR PERFORMANCES AND LISTENING TO A QUALITY SOUND. A- THE QUALITY AND THE RECORDING OF THE MUSIC WE WOULD LIKE TO LISTEN MOSTLY. B- THE DEVICES WE USE, AND HOW THESE DEVICES FIT TOGETHER. THUS COMPLEMENT EACH OTHER FOR THE BEST RESULT. THE PROGRESSIVE PSY.TRANCE IS MY FAVORITE TYPE OF THE MUSIC. WHICH MANY PARTICLES OF SOUND PRECISELY MODULATED IN THE SAME HARMONY . FURTHERMORE THERE ARE PIECES OF THE SOUNDS, NO MATTER HOW GROSS OR HOW FINE,THEY TRULY MAKE A DIFFERENT WHEN THEY TRANSFER THROUGH ONE'S AUDIO CORTEX . THE FIIO E11 AND THE SENNHEISER PXC 450 NOISE CANCELER COMBINED, ARE GIVING ME THE DEPTH AND THE DETAILS IN SOUND, WHICH I LIKE. MEHDI DANESHVARI BOULDER, CO.

Amazing!

March 20, 2014

A co-worker in my office brought in his FiiO E6 and I was impressed. But after doing some research, it just seemed like the better buy to get the E11. It was a sure bet! This little device puts out as much CLEAN power as my amplified Onkyo home entertainment system. I own a high-end set of around-ear headphones that rate 15-28,000 Hz and this amp makes my headphones thump with absolutely no distortion. You can't go wrong with this amp!

Once you plug it in you will hear the difference. I got it because I fly a lot and wanted better quality and more volume and when you crank up your device and the amp. you won't hear anything else. Well worth the price.

Short Battery Life

November 8, 2013

I purchased the FiiO E11 Headphone Amplifier to use as a headphone amp for my video camera while recording live events. I'm sorry to say I've been less than happy with it. While it does work as advertised to amplify the signal, I've only been able to get about 1.5hr out of the rechargeable battery and for my purposes, I need 3 to 4 hours minimum. I like the compact size and design, but if you are looking for something that will operate for more than an hour or two, you might want to look at other options. I did try to find information on battery life before purchasing the unit and thought I had read something on another website that indicated it would be more than adequate for my purposes, but I was either looking at a different device or the one I received has a faulty battery. I'm giving this product a poor review primarily due to the short battery life. Because of that, it really hasn't been usable for my intended purpose.

great little amp

October 30, 2013

This is a great little amp. Sounds good and 300mv is plenty of power. I ride a motorcycle and like to listen to music, my HTC phone with beats audio did not have the volume to hear music. I added speaker boost app and still could not hear music. I purchased the amp and it worked great. I did have a problem with the first amp the 3.5mm jack lost connection but sonic electronic sent me a new one no problem. Now I put short 3.5mm jack extinctions on both in and out connection and leave them in amp. Have had no more problems. Only bad thing is you can't listen and charge amp at same time. When I hook it to my home stereo, witch works a lot better with amp. Can't listen for a long time the battery has to be recharged.

Worked as Advertised

October 28, 2013

Recommend this product for any application that requires audio boost. I use primarily with my Nook and it does a great job of amplifying the weak audio output from the Nook. Recommendation - For ease of use it would be nice if the Input and Output connectors were at opposite ends of the body for my application.

fiio e11 headphone amp -- so far, so good

October 5, 2013

It doubles sound volume. much happier with the e11 than with the e05 and e06, which cost $27 but only amplify by 30%. skip the e05 and e06 and buy the e11 in the first place. if the e11 refuses to turn on, open the e11, remove original battery and then replace the original battery into the e11. (do not buy a new battery, just reset the original battery.) the e11 comes with instructions on how to do this. worked for me. has worked for 2 months under very heavy daily use. highly recommended. dents easily, but continues to work.

Amp that Adds a Nice Punch to any Headset!

September 17, 2013

For the money the FiiO E11 cannot be beat! I can personally tell the difference between amped and unamped now. I am now spoiled lol. I use these mainly with my V-Moda M-100s but you can use it on any high end headphones to give it that extra "ooMF" in your music. I like the fact that this unit is really small and can last a pretty long bit. It has a nice led, not too overbearing to show you that it's operating. The build is nice and rugged and I can feel confident if I accidentally drop it, it won't disintegrate on me. The rechargeable battery is a BIG plus in my book. It's just so convenient! And for the price paid, I do not regret one second on this purchase!

The Great FiiO E11 Kilimanjaro!

August 2, 2013

FiiO Rocks! I highly recommend this well made Headphone Amplifier. Several years ago I purchased the FiiO E5 and I was very satisfied with that product. So when I upgraded my headphones and digital music player I upgraded to the E11. A great value at under $60. I think it looks good and the design was well thought out. The guard for the volume control is great. Nothing complicated about the E11. It is very easy to use. It does what it is supposed to do, enhancing sound quality and volume.

Simply a great little headphone amplifyier

July 29, 2013

I use it with my smartphone to boost the signal. I needed something I could put in my pocket and provide quality sound. This fits the requirement perfectly. Considering the size / price the volume it produces drives my audiophile level headphones to nice levels and sounds great. I tried a different one, that cost more, but sent it back. Now satisfied.

It's a decent product. The body though, could be more firmer. From my experience it dents too easily, it doesn't hold up well to the slightest of mishandling.
