FAQ for KA1 mini headphone amp
Q1. How to use the KA1 with mobile phones?
(1)[Android-based mobile phones/tablets]:
The KA1 has two editions, Android (USB Type C) and iOS(Lightning). The Type-C edition can be directly connected to Android mobile phones or tablets. Play music to enjoy high-quality music.
(2)[iPhones/iPads]:
The Lightning edition can be directly connected to iPhones or iPads.
NOTE:
A. Only iOS10.0.2 and above are supported. Apple devices below this version cannot be supported because of the iOS itself.
B. How to download lossless music files to the FiiO Music App (iOS)?
Q2. How to connect the KA1 to computers?
(1)[Windows computers]: KA1 can be used driver-free with computers of Windows 10 and above, other version please go to our website to check and download the USB DAC driver.
(2)[Mac]: KA1 runs driver-free on macOS.
Q3. Does the KA1 support in-line control and answering phone calls?
(1)There is no physical button on the KA1, so in-line control will not be supported.
(2)Since different smartphones vary in USB phone call permissions, the in-line control and phone call functions of the KA1 are temporally unavailable.
(3)An incoming call will be passed out through the speaker and microphone of the mobile phone. So you can pick up the phone to answer the call without unplugging the KA1.
Q4. When connecting the KA1 to my computer, the indicator light is on, but the computer cannot recognize the KA1. What happened?
(1)The KA1 can detect if there are headphones connected to it. Only when it is connected to headphones will it turn on and automatically match the headphone impedance.
(2)Why is the indicator light not turning to magenta when playing an MQA track?
--First, please make sure the sound source is MQA format. Second, make sure if the playing device supports MQA decoding.
(3)What can be done when the KA1 is connected to a computer for DSD256 decoding, but the volume cannot be adjusted?
--When it is playing Native DSD, the volume cannot be adjusted through the software. Please adjust the volume on the FiiO driver panel.
Q5. If you need to download the Quick start guide, Windows USB DAC driver, please go to our official website to check it out.

I wish desperately that this was snake oil, but it's not. The listening experience is noticeably better, even just streaming Spotify at 320Kbps. I'd say this is a little overpriced for what it is, for 50 American dollars I want something a little more durable, but the sound quality is a stark improvement over your standard cheap USB-C to 3.5mm dongles. That being said, if you don't have decent headphones to pair with it, I wouldn't bother. My Meze 99s definitely sound way better through it, but it doesn't do much for apple wired earbuds. If you already have wired headphones you like, the KA1 is absolutely worth it... if you get it on sale. I'd pay $30-35, maybe wait for Prime Day.
There are too many easy points of failure (not enough stress relief at each end of the cable, especially considering the weight of the DAC side), and it's not very compatible with women's jeans. If your pockets aren't deep enough to hold your whole phone, this'll be dangling out of your pocket, putting stress on the cable, and your phone's charging port. The cable to my headphones has better tension relief, but the design of the DAC renders it useless. Especially given how short the cable is, I'd like it to be a little beefier. Its current design looks fancy, but doesn't inspire confidence when it comes to longevity.
Fiio, put this chip in a stiffer chassis and give it a replaceable cable. Killer audio processing, shame they cheaped out on the simple stuff.
This was the cheapest dongle Fiio sells and it works super well. I only wish it had a detachable cable since I worry about the durability of the twisted wired connection.
But I'll probably be only using this for intentional listening at home and on walks around the neighborhood so it shouldn't take too much of a beating.
Fiio has dongle dac amp models with detachable cords, but as a non-audiophile person, I'm not sure what throwing more money will get because this setup sounds incredible.
This setup: Apple Music Lossless > Fiio KA1 > Grado GW100x sounds amazing without breaking the bank.
