    "Probably the best budget audio amp out there!"
    Pros - Adds a great body and HiFi feel to the sound. Light and portable. Great soundstage and stereo separation. Bass adjuster.
    Cons - Poor battery life. Plastic construction feels cheap. Dock cables are a tad expensive.
    Great amp for the money, in my view best FiiO has done.

    This is my first amp and really I'm quite shocked at how much the sound quality can improve by just carrying one extra little box.

    Battery life and construction could have been improved, but of course that in turn would have added more weight.

    I'm sure I will try the E17 in the future, but for now E11 is amazing and fits my needs perfectly. :D

    I'm actually considering buying another one for backup, they are on offer at an amazing price at the moment on Amazon:

    "Fiio E11 Review"
    Sound: They expanded the soundstage a noticeable amount as well as instrument separation between the 2 channels. However, at first listen on the standard music app, i found the vocals to be a little muddy or low end heavy. Not enough treble to bring out the details of the instruments or the singer's voice. So I tried using it in conjunction with the EQu app and to my surprise i found it worked alot better. I increased the treble to bring out the details better but with that brought less bass than i really wanted. So I put the amp on bass boost 2 and high gain and now they have a pretty solid impact in the bass without losing the detail of the treble. Now the only thing that would make this amp sound perfect is if it could bring the mids/vocals a tiny more forward in the sound spectrum. I could adjust the mids in EQu, but the result made them sound not as clear- it went back to the result of just having the amp playing through the standard music app.   7.5-8/10
    Build: Decent. Since I got it used it was a little dented but hardly noticeable. the cover to the inside of the amp was backward when i got it, so i had to switch it back and even then one of the corners stuck out slightly. So even with the plastic exterior showing some wear and tear, i am confident the E11 won't up and break on me too easily.     7/10
    Overall: These are my 24 hour initial impressions. So I can't say this is my definitive conclusion as only time will tell. But for now, I'm giving it a solid 7.5/10

    "Great budget option for non-sensitive earphones"
    Pros - Great price, good sound, gain and "EQ" switches
    Cons - Sum hiss/hum audible on highly sensitive IEMs

    "E11 Is My #1 Amp Now"
    Pros - Clean, Lean and Multiple Settings (Extra Battery & Charger Included)
    Cons - None really, but opening/closing the case is funky.
    I purchased my E11 bundled with an extra, larger capacity battery and a charger off of Amazon. The additional items added a miniscule amount to the total, but greatly increased the overall value for me. It also negates the biggest gripe that folks have about the E11, which is not being able to use it while charging. Opening the slim cover without fingernails or a guitar pick (or the like) isn't all that easy and closing it makes the cover flex a little, which is a little scary. Nothing has happened with it... yet.
    If you are using the headphone jack on your portable audio source, this amp may transform your mobile audio experience greatly. I use it with my 1st Gen Zune 30 and a host of IEMs and 3 full-size cans (JVC HARX900, Shure 440 and Superlux HD681). I only use an LOD for the cans, but both outputs are viable for IEMs. It has three bass boost settings (0,1,2) two power settings and two gain settings to adapt to your phones' impedences. It pays to experiment with the settings if you aren't impressed with your initial sound. Fits in a pocket, even strapped to the old Zune... Very clean, very powerful and very adaptable. I like it a lot.

    Pros - reasonable cost
    Cons - none noted
    Brand new to the whole world of portable amps, but a really long time hifi addict.
    Bought this unit on recomendations of others online, and am not disappointed. I have nothing to compare it with of course. I am waiting for a converter to use it on my iPod proprietary slot, so I have tried it only on an Android phone and a Sony MP3 player. I have a variety of headphones, from Sennheiser to mee to Koss, and I must say the sound improvement is quite noticeable. Very pleased with the features, ease of use and available output improvement.

    "Fiio E11 Portable Amplifier by"
    Pros - rechargeable battery, great bass boost, plenty of power, outstanding price/performance ratio,rotary volume
    Cons - can't charge and play, cover is a little thin,doesn't come with LOD cable
    For a complete in-depth review you can hit my page where I've gone over this in detail.  I just wanted to list the pros and cons above and leave my feedback here with the star ratings so it can be added to everyone else's opinions.  For the record though, I don't think there's a better price/performance portable headphone amplifier on the market.  Just a crazy good value for a rich and powerful sounding amplifier.

    "Fiio E11 - Brilliant and Cheap"
    Pros - Nice Build, Brilliant Bass, Over-The-Top Volume Control, Ease of Use, Long Battery Life
    Cons - May Destroy your ears if you turn it up too quick
    Relatively short review, but here goes. (I'm using the Ratings as a Section Template)
    NOTE: This is the only amp I have ever owned, so it may be biased!
    I bought this amp about a year ago now, and I must say first off that it is fantastic! People say that the FA-003 doesn't need amping, but I really felt a difference immediately after plugging it in.
    It's as if the sound just became clearer and had more power. It was really quite astounding for someone like me, who has never used an amp before this one.
    As a bonus! It has a bass control. It's not that customisable, it's only OFF, 1, 2. But I find it to be more than enough. I practically never use the 2 setting (that's for bassheads, i'd say), but I do like to use the 1 setting when I want more "Oomph"
    The bass that is added is well done as well - it doesn't muddle the rest of your music at all!
    -Build Quality-
    The first thing you will notice about this amp is that it is mostly made of metal. It's not going to break easily. The only thing that may be fragile is the jack. The jack broke for me after about 4 months constant use - Granted it was in my pocket and I wasn't exactly protecting it, so overall, i was careless!
    I actually tried throwing mine, after the jack broke, on the floor with moderate power. Nothing really happened; some of the plastic got scratched a bit and it lost a bit of paint, but apart from that it was intact.
    All in all. This thing is a TANK! (as long as you aren't careless with the jack - I recommend an angle adapter if you're using a full-sized set with an un-angled plug)
    Let's be honest, this thing is beautiful. It's sleek, has neutral colours, and the shape of it is brilliant for travel. It's a little bit smaller than the average smartphone, but it's about the same thickness (In fact, mine was mistaken for a phone twice.)
    There's not much more to say - The design is eternal and beautiful.
    This thing costs nothing. Not in comparison to what it gives, anyway. Spending the $65 on this vs. Spending an extra $65 on a headphone - I would say that the FiiO wins most of those battles. It just adds so much life to your music!

    "Fiio e11 can it hang with the big boys?"
    Pros - Powerful and slimm
    Cons - Volume knob
    There has been a lot of talk lately about affordable portable amps. Coming from using high end portable amps in the past I was quite skeptical. I thought that there is no way a sub 200.00 amp could compete with RSA and Headamp. I had the same mentality towards portable amps as I did towards customs. I guess I thought that if you could not afford the big boys then you really did not need an amp. I have seen so much change in the portable music industry in the last six years I have been a member here. Amps and customs were for the elite audiophile and that justified their price.If you wanted to Join the club you had to pay.
    Let me give you a little of my background gear. I have tried several high end portable amps over the years. I started with the RSA hornet. I was so thrilled those many years ago when it was released. I was so amazed at the sound it could produce through my Custom ultimate ears. Shortly after the Hornet was released Ray came out with the Tomahawk. Hey a smaller portable amp that could perform better yet more battery life. I jumped on the wagon. As soon as I jumped purchased the Tomahawk Justin from Headamp posted about this new dac/amp called the Pico. Man my world was spinning around, I had to have it. Now I could use a dac to improve my pc sound and then take it on he go with my ipod. I was so thrilled with this amp till Ray posted about his new ultra small amp called the P51 Mustang and its Dac/amp counterpart called the Predator. I managed to hold out on this amp until recently. I have been enjoying this amp for a few weeks now.
    Well with all the talk of affordable amps lately, I decided to contact Fiio and ask a few questions about their idea of providing cheap amps to the community. I thought it was another Chinese company trying to rake in the bucks on the efforts of people like Ray Samuels and Justin W. I thought this was tragic. I thought it could leave a bad impression and possible drive new audiophiles away from the hobby because of a shoddy product. When Fiio offered to send me an e11 and a L9 ipod LOD I agreed. I thought I would finally be able to differ people away from this product and protect them. I promised to give a honest review no matter what my biased beliefs were.
    Well two days ago I received a package from Hong Kong by DHL.It took about four days to arrive which is quite good seeing as they did not send it express. There was a small box enclosed in the DHL envelope. Within the box there was some styrofoam protecting a small silver box about the size of a wallet and a small static envelope.
    The silver box contained the E11 amp, a 3 inch 3.5mm to 3.5mm interconnect, short usb mini cable, and a silicone band. It was packaged quite nicely and accessories were great. The anti static bac contained the L9 right angled LOD.
    The construction of the amp is mostly plastic.The volume knob is an ALPS potentiometer. They do this to ensure a low noise and good channel balance. There is a built in high-performance lithium battery. It is a BL-58 model. Basically that is a cellphone battery that can be easily replaced To one side you see five 220 16v RVT solid state capicators. Underneath the battery you see a switch to change from high to low power.
    As you look on the outside edge of the amp you see gain switch and a 3 position eq switch. The other side has the usb charging port, and the front has the volume knob, input and output connectors. There is a blue power led and red charging led on the top of the unit.
    The frequency response is 10~1000Khz. Signal to noise ration is ≥98dB. Crosstalk is 60dB. Gain ≥ 12dB High, and ≥ 6dB for the low. total harmonic distortion is <0.009%(10mW). Voltage on high is 300mW(16Ω), 200mW(32Ω), and 35mW(300Ω). Voltage on low is 120mW(16Ω), 88mW(32Ω), and 13mW(300Ω). The recommended headphone impedance is 16~300Ω, and the input impedance is >5KΩ.
    The size is quite acceptable for a portable use. It is quite thin and light. It measures 92.55mm x 54.2mm x 13.4mm and weighs 65g with the battery.In my opinion it is easier to slip in the pocket than the p51 and ipod combo.
    The L9 lod is a right angled 3.5mm connector with a low profile 32pin connector. It uses two 6cm PCOCCA-A copper wires with PFA insulation and a cotton rope medium surrounded by a black TPE sheath. the impedanceof the wire is a max 0.07Ω and has a resistance of min 2MΩ.
    I have been listening to the amp almost constantly for the past few days and it has about 30 hours on it. The battery lasts between 10 and 12 hours. and takes about 3 hours to charge. I was using my ipod classic 7g with ALAC and 320 KB/ps files. Iems I used were my ultimate ears ue-5c, ue-11 pro, and jvc marshmallows. I will use other iems as I get them in shortly. I was unable to use fill size cans as I don't have any on hand currently. I used many genres of music from Loreena Mckennitt to Disturbed. Basically every genre other than country. 
    There are a few things I don't like about the amp. I don't like the how the volume knob was designed. I understand that they did this to prevent accidental operation of the volume knob. When the unit is piggy backed with the ipod it is very difficult to manipulate the volume knob. They could help prevent this by including some sort of feet to attach like RSA and headamp do. This would provide a bit more room between the amp and the ipod. I also feel that in this configuration the L9 is not suited.
    I do find the amp provides more than enough power for my iems and probably enough for full size cans. With my ue-11 pro I have the volume on 3 with a low gain and no eq. I would be afraid to turn it up any louder or put it on high gain as it would cause hearing damage. In my opinion it should be able to power most any iem or headphone out there you would take portable. There is plenty of detail and separation in the music. There is a strong punch in the bass and really tightens up sloppy bass. For the most part I dont use the eq, however I think it is a good idea for someone that does not have their desired bass in their cans. you can use a flat iem to listen to classical music and then add some bass to techno or rock to make the same iem fun.How does this compare to high end amps? Well the p51 has a larger soundstage and a bit more accurate bass and detailed highs.I think it would be quite hard in a blind test to tell this was not a high end amp.
    The L9 is not a bad lod for the price ( around 20.00) there are a few things that could be better. I dont think the right angled connectors suit my current needs. The LOD sounds good. It is a bit warmer than the RSA lod I am comparing it to, but is more flexible.The 30 pin connector is a bit loose. It wiggles in the line out of the ipod and a little too easy to pull out. You can just lightly pull on it and it releases. I worry the connector can come loose when removing from my pocket.
    In conclusion Fiio has opened my eyes. It is quite possible to provide a great product for an affordable price. There is plenty of power to amp most any can and has a great sound. I do prefer aluminum housings over plastic and would like a different knob or silicone feet, but this is a solidly built portable amp with great accessories. I love the silicone band they include. It is a good amp no matter how much the price tag is. I have no problem recommending this amp alongside the Pico, P51, and the likes. I do feel there are better amps out there but at 3x-5x the price.
    The L9 on the other hand is different. I feel it could be a lot better. It has great sound but I just cant get over the connector. I would like to try a different LOD from them and see if it is better or suits my needs more.
    I bought some silicone bumpers and it seemed to have fixed my problems.

    "What a difference!"
    Pros - Lovely smooth sound for hardly any money. (£40)
    Cons - Volume knob isn't properly fixed to the potentiometer spindle; it has a little bit of "give".
    Well, "impressive" doesn't even come close...
    I have a Sony NWZ-X1050 which sounds awesome through my car stereo, my home stereo and, of course, the noise-cancelling earbuds that came with it. The problem is that I don't like earbuds.
    The only pair of working 'phones in the house at the moment is a pair of Sennheiser PX200 cans. These are renowned for having very little deep bass and, because they're so small, the isolation is practically non-existent.
    Not any more! I amped them through the E11 and now, not only are they loud enough to drown out any extraneous external noise, but they actually have whump and rumble! They have some bass at last, and very smooth it is too.
    I wish the weekend would hurry up and get here - I can't wait to go out and get some proper cans...
    My only gripe with the E11 is that the volume knob has a little bit of slippage on its spindle, though because of the design of the case, it isn't going to fall off, so I can put up with it.
    [EDIT] I've since purchased a FiiO L5 LOD Cable to go with the amp. It's very nicely put together, too. It has nice thick cable, and both plugs feel solidly attached.
