Generally great sounding and a solid performer in a neat package. I would recommend this unit, my only complaints are minor nitpicks.Pressing in the knob for 5 seconds to turn the unit off is a pretty annoying design choice for something you will likely want to do every time you use the unit. I have read some reviews that seem to think turning off the unit is impossible - this isn't true, but it highlights the poor design choice.It also seems to take longer than necessary to boot up. This hasn't been my experience with previous headphone amps at a similar price point.. Is it because I need to have ~7 seconds to have time to read "FIIO K11" on the display?The volume knob can only select at increments of 1, so if you want to make a large adjustment to the volume, ...

The default was not appropriate for me.

So far I was more into using some high-end mobile devices for listening music and This is my first time I thought to use a dedicated DAC/AMP for headphones. To my surprise this little wonder from Fiio have performed beyond my expectations. It has kickass soundstage, excellent flat response and mind blowing power. Wish it had auto power down feature when not in use. But other than that K11 works flawless for your needs.

Absolutely happy with the performance of the product, there are a few glitches with the software but I am expecting them to be ironed out soon. Tested the single ended output with HD 650, HD 300 pro, HD 569, MDR 7506, SHP 9600, source was Apple hi res Lossless and lossless via iPad through usb c and lg Oled tv with optical input.I am impressed by the quality and neutral sound of this product.Power output is enough to drive the HD 650, would love to try the balanced output once I get the balanced cable. Got an ifi 3.5 mm to 4.4 mm to use the balanced output but unfortunately it has the exact same volume as the single ended output, maybe it’s a product limitation.Please make sure you use this with a high quality audio source otherwise you will not be able to ...

Bought to replace an older, cheaper DAC/AMP I'd gotten for around $40. The K11 works wonderfully for all the headphones I've got (Takstar Pro 82, Hifiman HE4xx, Phillips SHP 9500S mainly), and has a wide array of features as well. Getting to updating the firmware is a must however, as there are some quirks that the K11 has on its stock firmware that disrupt the listening experience. Thankfully firmware updates aren't terribly painful, though it took some digging to find proper instructions. Once that was settled, it worked beautifully though! Great looking, well functioning buy for those who are looking around this price point.
I purchased this item for line-in to the Denon Heos Speaker. The connection works (3.5mm). However, many songs the speaker distorts. Obviously, this could be internal to the speaker as well. However, this amp sends less power to the unbalanced headphone amp than to the balanced connection. I missed that in the specs. Quality of the amp and options is nice. Just not quite powerful enough for my application.
Having read reviews about sound delay or what not and needing a firmware update, I decided to get the K11 anyways. I had downloaded the latest firmware and had it ready to update when my unit arrived but to my surprise, it aldready had FW version 122 installed. All I had to do was plug it in and enjoy. No issues so far. I have the ifi Zen Dac V1 and will still use it whenever I want more bass in my music and the K11 for when I want a more neutral / analytical sound. Both are great! Headphones/IEMs I use are SHP9500, 58x, ATH-WS1100, Fidelio X2HR, Kato, Zero 2, Aria. Pretty good dac/amp for the price.
