FiiO KA11 USB C to 3.5mm Audio Adapter 32bit/384KHz, USB Type C Dongle HiFi DAC Amplifier for Android/iOS/Windows/Mac (Silver, TC)

Fantastic DAC for the Price – Plug-and-Play Audiophile BoostI’ve been using the FiiO KA11 with both my iPhone 15 Pro and a Google Pixel, running it through a USB-C splitter—and it works flawlessly. It was completely plug-and-play, no setup needed.I tested it across multiple apps—Tidal, Spotify, Apple Music, YouTube, HBO—and it delivers excellent sound consistently. The clarity and depth really shine, especially when paired with my CCZ Melody and Moondrop Chu2 IEMs. The iPhone’s EQ settings (I love the Late Night preset with the Melody) take it even further.It does warm up after about 15 minutes of use, but I didn’t notice any unusual battery drain. I have over 100 hours of use out of mine so far. Build quality is rock solid—it feels heavier and more premium than you’d expect for a $33 dongle.If you’re looking for a compact, high-quality USB-C DAC/amp that just works and sounds fantastic, this one is well worth it.

Compact, powerful, low latency DAC for entry level people getting into IEM's, or if you just want more powerful audio for your headphones. They work great, sound great, the build quality is top notch, and I plugged it into my Windows PC and it was automatically detected, same thing with my Android device. so this DAC can be used for 2 different devices. The low latency also helps for when you are gaming.

Initially had trouble connecting via USB C to Google Pixel 9 Pro XL. Eventually worked. App support is woeful as the app back and setting icon buttons do not work because the app full screens overlapping notification bar. Less than one month after (purchased mid December, now January 8th) device stopped connecting to the phone. And if it does connect it connects and disconnects over and over again. Reinstalling the app has no effect on the connection issues.While it worked it powered my IEMs and headphones admirably. Strong enough power, great soundstage, and detailed. It's on the clinical side of balanced as highs are crisp though it's production can be fatiguing over certain frequencies, but this issue can be EQd out. Bass is strong and powers headphones bass output fast and accurately without out bloat. The dongle is fairly neutral and receives EQ well. To my knowledge there are no EQ settings, in the FiiO app for this particular product, only filters which functions as narrowing or widening soundstage, giving more presence and weight, filter to filter.Overall it sounded good, while it worked, for it's size and purpose and price. But it's stopped working, so I can't recommend this product.

I’m very impressed with this little dongle DAC! Simple and powerful. I use mine with an iPhone 16 and an iPad Air. Easily visible indicator differentiates between regular and hi-res signals. It powers my Sennheiser HD6xx and everything I throw at it with ease and sounds great. I even have a pair of AKG K240 cans that are 600ohms and very hard to drive. This little adapter gets the job done. It does get warm but not really hot. For the money I don’t think you can do better.

While, I bought this with a pair of Fiio JT1 headphones, they're pretty great, works well without issue on my phone, I use it in minimum phase, fast roll-off in the app and also use it on my Nintendo switch for clearer audio quality. Audio quality is really good, it even drives a 250 ohm oneodio monitor 80 open-back I have decently enough.my main issue happens to be with Amazon's fire tablet. Not particularly sure why, but it randomly cuts out. Which sucks because the fire max 11 I have has dolby audio built in. Not sure if it's the dongle or if it's an issue with how Amazon locked its OTG features and it might be causing an interference. The audio is very clean and defined but then cuts out at random like the audio is catching up, unfortunately it does get pretty warm too. I like the audio quality indicator.The usb-c fits securely on my devices.,it also feels like high quality aluminum, the black/silver gives it a minimalist look and the headphone jack locks my headphones connection securely.

As a dac/dongle it provides more than enough power for even some harder to drive headphones. It has a stylish design if that matters to you and is small enough to not get in the way. The sleeve on the cable sadly starts to fray pretty easily but hopefully it keeps up and doesn't affect the sound and connection. After a few months of use I can say this is perfect for android users. The app it's intended to work with is a bit... buggy sometimes and the connector does get hot enough that it can potentially burn you but that's only a real issue if you fall asleep on it.
