  • Compact and Lightweight
  • Standard 3.5mm I/O
  • Multiple Gain and Bass Options
  • Replaceable Lithium Battery

The E11 Headphone Amplifier from Fiio is a compact and lightweight headphone amplifier that offers high-quality audio, ideal for portable music devices. The amplifier has standard 3.5mm input and output connectors for compatibility with a variety of MP3 players, CD players, computers, earbuds, headphones, and other devices. It has a heavy-current 3-channel amplified circuit that lowers output impedance. It also provides high efficiency and a low-noise power boost. It provides precise and even sound pressure levels and a wide dynamic range.

The convenient volume control uses a closed APLS potentiometer to ensure low noise and excellent channel balance. The amplifier offers 3 levels of bass boost and 2 levels of gain to meet your personal preferences and adapt to different sound sources. There are also high and low voltage options to meet different needs. An auto-lock protective circuit will turn the amplifier off automatically in the event of abnormal activity in order to protect your headphones and minimize the risk of hearing damage.

The amplifier operates on a high-performance BL-5B Lithium battery that is easily replaceable. The battery provides approximately 10 hours of operation per charge, allowing you to listen all day. The amplifier has charging and power indicator LEDs to give you a visual cue of operation status. A charge priority function will cease operation while the amplifier is charging. Once the battery has been charged and the amplifier is unplugged, operation resumes.

    i bought this amp along with a pair of ath m50's and i have to say i am blown away. it even makes my 30 dollar portapro's sound beautiful.cheap headphones sound even worse with this though but the difference is actually amazing if you have a decent pair of headphones.it would be perfect if you could charge while using it.and i actually considered knocking off a star for this shortcoming but after thinking about it it still deserves 5 stars. there is a battery and external charger available from (which is a must have for this amp imho)i am now a huge fiio fan and i plan on buying an e17 and e9k next month for my desktop setup and using the e11 as my portable amp.

    first off let me say that I have owned an e12 and an e11. the e12 is amazing ,strong and clean,lasts long and charges fast. I dj electronic music using many different cans .usually 24 ohm to 36 ohm. the e12 was stolen ,so for financial reasons I bought the e11.it was ok for the price .it is no e12. not as clean or strong. lasts less and takes longer to charge. I suppose the e11 will suffice for my use . but knowing and hearing what an e12 did makes me want a little more. if you can afford it go with the e12. its power is endless and clean. the e11 will break up at high volume heavy bass. I use this with a 5th gen ipod ,that has a wolfson dac with line out playing lossless files. so my source is clean. thinking of returning e11 and paying the difference. gonna try this for a week more and see if I change my mind. the e12 is heavier and all aluminum. the e11 is light and all plastic.it really depends on your finances,requirements and uses. in my opinion , if you have the xtra money go with the e12 .you wont want or need more but if you do need more then it is available . with the e11 you might need more , and it does not have it available .

    Excellent Performance

    By Rob

    from Westfield NJ

    Comments about Fiio E11 Headphone Amplifier:

    Performs exactly to spec. Exceptional result driving Bose QC25 noise cancelling headphones. Good battery life. Used to monitor high and line impedance line level audio. Would provide a perfect headphone source from a TV audio line out independent of the speaker volume. Good value for money.

    Comments about Fiio E11 Headphone Amplifier:

    For its price, I would say it is a bargain.Overall, less than impressed with the said product. While it will boost your audio input from any devices, there's barely any difference. Bass boost was subtle and the higher frequency still remains unbearable for hearing, especially at higher volume.With charging time max of 3 hours, this can go on for 8 hours. However, on my experience, it last lesser than promised when you constantly play audio. Poor battery life. Worst part is there is no auto-off feature. Biggest let down of all.3 stars for well packaged item. It came in a metal packaging.

      Perfect match for my Vmoda m100s. Definitely gave the m100s that extra punch especially with the bass boost. Be sure to get the L9 cable for a much more clean sound.

        Comments about Fiio E11 Headphone Amplifier:

        Cleans up the input nicely, and the output is relatively impressive for the price-point. The multiple EQs are useful, and don't distort your music or degrade it, it brings some elements to front stage while others aren't as prominent. The battery life is a nice surprise, far exceeding the 10 hours specified. I've charged the E11 twice since I received it over a month ago, and use it nearly every day for 2+ hours. Overall, a great product, and for $ , everyone should keep one handy.

          I just need something to boost the output of my laptop to a small pair of headphones. I was interested in a louder signal and this unit provides that. I also like how compact and light the unit is. Note that this company has recently come out with a newer model that is priced a bit higher. Those considering this should also look at the new model to see which unit fits their needs best.

It sits on top of my iPod on the fuel tank both in a pouch and use Klipsch S4i II headphones.I finally really enjoy my music during my rides.It has great bass, it is compact and the volume could be adjusted on the run with the small wheel.This is an excellent product with quality sound.I also purchased the E17 which provide more tone control.

          Comments about Fiio E11 Headphone Amplifier:

          I bought this amp to use with my Samsung smart phone which quite frankly has lousy sound output. I have also ended up using the amp with pretty much every other device I own as it makes the sound just incredible.
          There are 2 gain settings (High/Low) and 3 bass-boost settings, I pretty much only run it on Low gain and either 0 bass boost or 1 bass boost. I only use the High gain setting when I really want to rock out and melt my ears :)
          I own a pair of Vmoda M-100 headphones which have nearly infinite amounts of distortion free bass, certainly more than my ears can ever handle, so this amp is great for driving those headphones to the limits.
          My only complaint is that it is fairly bulky to carry around with my phone and also the battery only lasts about 15 hours of charge so it feels like I constantly have it on the charge overnight for the next day.. which isn't a problem but now that I have 3 or 4 USB rechargeable devices, feels like my life is governed by re-charging cycles :)

            Use the E11 to amp up a low level headphone signal used to monitor audio during recordings. Audio coming from the E11 does have a hissing sound, so not the greatest sound qualiy. But it does what i need.

              This little amp does it's job well. Increased volume perfectly up to 10 DB as advertised. Its so small and light, I was amazed how light. It's perfet except for one flaw. You cannot charge it and use it at the same time. That caused a shutdown of the device. I had to remove the battery to get it to come back online. Otherwise I love this little thing. Its very well designed. I'm very happy.

              Sound quality is fantastic. Drives my Shure SRH840's beyond adequate levels. I'm pretty sure my skull will crack before the sound does. I would give it a solid 5 stars except for two niggling flaws: 1) the back of the case, which covers the battery, does not latch very securely and will pop off with very minor falls and occasionally in my pocket, and 2) the input and output jacks should be swapped, as mentioned by other reviewers. Aside from that, this is an incredibly satisfying little amp.

                I have with me my second pair of this amp and really VEXED at the company who made it. The headphone jack is really bad for a portable amp. I have had the same problem with both amps that I purchased and tried to reach out to the manufacturer, who by the way is all the way in China, with no luck on how to get it fix. It is not an expensive amp however it is cheaply made.

                i bought this amp along with a pair of ath m50's and i have to say i am blown away. it even makes my 30 dollar portapro's sound beautiful.cheap headphones sound even worse with this though but the difference is actually amazing if you have a decent pair of headphones.it would be perfect if you could charge while using it.and i actually considered knocking off a star for this shortcoming but after thinking about it it still deserves 5 stars. there is a battery and external charger available from (which is a must have for this amp imho)i am now a huge fiio fan and i plan on buying an e17 and e9k next month for my desktop setup and using the e11 as my portable amp.

                I'm using it with my Zune HD and my Sony XB 700, so this amp is really wonderful for a dark sounding DAP or headphone, the bass has very nice attack as well as detail but it can be a tad bit aggressive for more transient head phones. The power is also plenty for headphones at or under 300 ohms. Good buy!

                  Just wanted to update that the connections are solid and that the 3.5mm cable was the cause of the intermitentance that was occuring.

                  Sound is awesome if you are looking for a portable amp this one is very choice.

                    Biking Working out Blue led is coolloud ;)Step up from e6 and e3RechargeableClean sound and did i mention loud.Nice hits with drums. I listen to metal.Life would be worse without it.I use it with UE triple 10'sJack inputs seems to be slightly sensative to pressure applied in or around my cargo shorts/pants pocket on occassion while active, thus sound cuts out in one ear which is really annoying. This happens very very infrequently but still occurs.Design is solid and gain/eq options are clean sound options that add bass and volume.$60 is a sweet deal for this piece of audio improvement. If you like your music loud and clean I recommend it for sure. Smaller than an iphone and very slim.Rechargeable through USB port.Makes everything I listen to sound better. (period)Slight hiss, less than e3 and e6 but still present

                    E11 is a better amp than Zo2.3 which I also own, the bass is tight and satisfying compared to Zo.
                    The build and finish is simply best than any pocket amp for this price. Whether IEMs or over the ear headsets its drives both nicely. AKG K450 performs even better when connected to the amp vs direct to ipod.
                    I'm giving it 4 stars and yes I would still buy this again if I lose it. If not for the fizz at times when near a phone it would be the best amp that I have ever see of this size.
