Needs a Firmware Update

Unable to control volume via Windows, saw that some other people are also facing this issue. I'm hoping for a firmware update.

Vikash K (Hyderabad)
K11 is one of the best neutral budget dac, amp

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 realise their potential.

Hey Vikash, thank you so much for the amazing feedback! It means a lot to us. We are so happy to hear that you are loving our products and services.

Opens up tunes unheard earlier in tracks. Far better than small form factor dongle form dacs

Sharing my review after 18 days of usage. Tested with Beyerdynamics Dt 880 Edition, AKG k275, Sony WH-H910n (via wired Aux cable) in Medium Gain & USB input mode. Beyer & akg took sounded better ,not as neutralish as quoted in some reviews. Bass is prominent with mid bass clarity & optimum sub bass presence. Flawlessly handled 192k PCM coded Flac files. Bass thumpyness also has satisfactory presence. USP being the Top part illuminated RGB pulsating/static Fiio Logo.
Being mostly metal head & hyperpop listener, worked fine. Intrument sounds which I heard for the first time after plugging beyer dt 880 ed cans to Fiio k11 was absent earlier even after playing LP flac files using my Dell Alienware inbuilt Realtek & Nahimic sound engine. Regarding Youtube & gaming working fine but dunno who's gonna spend 12k for enhancing sound quality for playing games & streaming youtube.
I was earlier worried regarding authenticity of device or whether refurbished, but that all was answered since Fiio devices comes with scratch card pasted on the device box with 20 digit code that can be verified over the Fiio Website.

Well what's the best part is the device works super fine with Samsung phones (used S22 Ultra) for testing with usb c to c male cable that comes with 45Watt samsung charger. While upon my enquiry headphonezone support did tell me theres shear possibility that it will work with samsung s series device so opt out of choosing fiio k11 if to be used with aforesaid as DAC. Also, Saw some reviewers sharing review that volume boost control not working with windows, i tested myself with windows k11 works fine but do have to installing Fiio USB DAC Driver Fiio_v5.58.0 erstwhile if one ends up installing Fiio_v4.47.0_2018-08-03 it will not show up Fiio K11. Sound quality is good I can tell that since I use multiple cans such as Buds 2 Pro, Sony WF1000xm3, Sony WH-H910n, Beyerdynamics dt 880 pro, Akg k275.
Regarding sound Signature k11 is more or less has a darkish flavour that works best with metal tracks.

Able to drive DSD 128 (.dsf) file smoothly without any hiss or hiccups on S22 Ultra in HiBy Music player app with DSD mode selected Native in HiBy Music setting.

Hey there,

Powerful and clean DAC/Amp minus the bass

FiiO K11 is powerful enough to drive my AKG K702 and looks really good. It is well-made. Using my DT 900 Pro X and HD 560S, I am able to hear more clarity in music with K11 compared to my Creative Sound blaster G3, but where it lacks is bass. Some Chillout mixes sound better with my G3 but K11 definitely has clearer output. So far so good, happy with the purchase at this price point.
