FiiO JadeAudio KA1 Headphone Amps Amplifier Tiny USB DAC High Resolution 3.5mm Lossless for Smartphones/PC/Laptops/Players(Type C, Black)

By far one of the best sounding headphones DAC & AMP for this price. The sound quality is a huge improvement over the cheaper < $20 ones you can find all over the place. The audio is truly high quality and HiRes. Here are the pros: 1) HiRes is true, accurate, and sounds great. MQA also works as advertised 2) It's small and easy to handle and keep in my pocket 3) Despite my initial concerns, the braided cord to the phone USB-C jack is actually VERY sturdy and very well made. It has not untwisted on me even a tiny bit! Very impressive they were able to accomplish that 4) It works with just about any phone or computer 5) The jack is sturdy, the build quality is amazing, the all-metal casing makes it feel purposely made as well as you can Here's the poor things I found: 1) It does get warm, and especially so if placed in your pocket or under a blanket. It does have a good bit of heat that comes off of it. When playing higher sample rate tracks, such as 96kHz it will get much warmer 2) The app is practically useless and offers no added features Overall I am very impressed and would purchase again and again. Despite my few poor findings, I still rate this 5 stars for exceeding all my expectations. Also if you're worried about the braided cable: don't be. Mine has held up perfectly, see photos

Great DAC and sound and drives my Astral Ears earphones well. Gets warm because it a proper amp, not some tiny iPhone 10 cent chip. Not a terrible battery drain which I was worried about. While better sound than Bluetooth, the downside is you can’t charge at the same time. If you’re ok with that caveat, you’ll be happy like I am. A balanced sound and great buy for me. Like it’s other products, this Fiio gives great value.

Every part of me wanted to write this off as a scam. You don't need a discrete dac for mobile listening, cheap Amazon adapters and my laptop's stock headphone jack are fine. Right? Wrong! 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.

As a musician, I often need to play recorded material into the mix. The easiest way to do that is by plugging the phone into one of the stereo channels on my mixer. Sadly, phones don't have 3.5mm audio jacks anymore, so like most people, I was using a cheap USB dongle. It worked. More, I cannot say. I finally got sick of the crappy sound and decided to find something that would be better. In the world of the audiofile, spending hundreds or even thousands of dollars is typical for a good audio interface. I wasn't prepared to do that for this application. Enter Fiio. I have used Fiio products in the past and they've always delivered great bang for the buck. The KA1 is no exception! The high end is far more distinct than the cheap dongles, and the sound stage is noticeably larger. Finally, the bass is very natural and well-defined without being boomy. The build quality seems very good. The cable looks to use good materials and the casing on the body is aluminum, not cheap plastic. While this device basically sits on my desk, it is very small and portable if you have a pair of wired headphones you want to use on the go. This will sound much better than what's built into your phone.

Use this with my Audio Technica ATH-M50x and my Sennheiser 560s. Listening on Spotify at full quality. The dongle really helped power both pairs of headphones. With the Sennheiser open back cans the sound stage really seems to open up pretty noticeably. The Audio Technica cans have more pronounced highs and mids to go along with the already pronounced lows. For $50 I'm super pleased. I no longer have to max out the volume to get good sound. The dangling cable on this unit seems less than durable but only time will tell. IMHO this is definitely worth a try at such an affordable price. Great addition to my setup, especially for use out in the everyday world.

Great audio quality with one fatal flaw, the USB C cable is not built to last - and without being able to replace it it bricks the entire dac. I think this is good for beginners but anyone who uses this regularly is likely to encounter problems with integrity over time. Ultimately disappointed, but wow what a bang for buck when it worked.

I am beyond satisfied with this adapter! The volume level is great, much louder than most other adapters I've tried and the quality and clarity is noticeably better as well. This is everything I need out of an adapter as a lover of headphone listening and musician. And it's only 50 bucks, works great in my car too

Not gonna lie I kinda hate this thing. Yes it makes the sound better on my trucks stereo compared to the default aux but there's one major flaw. The cable is about the thinnest and cheapest feeling cable I've ever had on a device. This leads to it "disconnecting" every time I hit a bump on the road. Extremely annoying as it stops my music and I have to try to get it playing again while driving. I just stopped using it. I don't recommend you buy this product. My 5 dollar monoprice cable makes this thing a joke.

Para el que quiera y busque calidad sonora sin mayores problemas, simplemente "enchufar y listo" a través del jack de toda la vida para auriculares, éste es su dispositivo. Fiio, calidad de primera línea, es una garantía. DAC muy compacto y ligero, ni se nota. Casi pesa más el conector de mis auriculares. Para los que no saben muy bien de qué va el tema: cualquier reproducción desde un medio digital como es el caso, necesita para escucharse a través de auriculares pasar primero por un DAC para convertir esos 1 y 0 a una señal eléctrica "analógica", y aquí empieza la realidad sonora. Este DAC es la manera más simple y directa de avanzar muchos enteros en este punto, y de aquí para arriba y sin parar (hay de todo y todo de más caro a mucho más caro). Así que es un excelente punto de partida. Económico, sencillo (no hay que hacer nada), y calidad. Es económico para lo que ofrece. Simplemente buscaba poder añadir auriculares (NO BLUETOOH, primer paso importante para obtener calidad real a costa de la comodidad, eso sí) a mi teléfono, en mi caso S23 Ultra que funciona perfecto, simplemente enchufar y listo, a través de Poweramp (aplicación casi obligatoria en el terreno que hablamos, hay más ...). Para mayores "avances" ya tengo un DAP de la propia Fiio, pero ésto ya son palabras mayores, y se trata de añadir salida por cable a un dispositivo sólo USB C evitando llevar dos reproductores (trae un adaptador a USB A para poder enchufar al PC p.ej.) . En el caso de los móviles más sencillos con salida por cable, es la solución ideal, ya que ni por asomo van a traer un DAC integrado de este nivel, y ahi será donde mayor aportación tendrá; pero...... los auriculares son esenciales. La música que escucho es en FLAC, aunque por espacio a veces en MP3 a alta tasa de bits. Reproduce sin ningún problema cualquier tipo de archivo. Aún no he probado DSD, pero imagino en la misma línea ¿Se aprecian cambios desde Bluetooh al cable con un DAC? Desde luego; aunque entra en juego disponer de auriculares a la altura, donde existen modelos excelentes a precios asequibles como KZ. El volumen que se obtiene es adecuado sin meternos en auriculares complicados, que no es el caso; para eso hay otros DAC. Yo escucho perfectamente la música a volumen más que correcto, y está en el 11% sobre 100%; se calienta ligeramente (es metálico y ayuda a disipar el calor, nada preocupante), y consume de la batería del móvil (así no hay más complicaciones con baterías externas, etc. (hay adaptadores que permiten en el USB C estar cargando y a la vez tener conectado el DAC o cualquier otra cosa. NOTA: DACs de mayores prestaciones y alimentados por el propio móvil, consumen bastante más, ojo a este punto. Muy poco consumo en el caso de este DAC. Reune las tres "B", Bueno (sin duda), Bonito (a gustos...), y Barato (para lo que ofrece). Absolutamente recomendable.

Je n'ai rien à reprocher à ce matériel qui était passé dans "Test-Achats" de ce mois. Je me suis fié à leur essais et j'ai directement commandé sur Amazon. En 48h j'étais déjà à l'écoute! j'en suis ravi !

Revisé muchos foros donde se recomendaba, y la verdad es que no decepciona. Si se aprecia la mejoría en la calidad de audio que se entrega

If you want to get a high-sound quality out of the 80-ohm DT770 Pro, you can get this tiny amp. It works really great if you have a USB-C (Lightning) port on your PC motherboard. I like how it works on almost all the smartphones that support USB-C. It's good for the price and it comes with a USB-C to USB-A adapter, which means you can connect it to the motherboard even without having a USB-C port! But for the best performance, it's better to connect it to the USB-C port directly. This will do a good job for the 80-ohm DT770 compared to an expensive amp.

Ich bin wirklich begeistert vom FiiO JadeAudio KA1! Ich nutze ihn vor allem für meine In-Ears, und der Unterschied zum normalen Smartphone-Klang ist sofort hörbar. Der Sound ist unglaublich klar, die Höhen sauber, die Bässe knackig, ohne zu übertreiben. Auch leise Details kommen richtig gut raus – das macht richtig Spaß beim Musikhören. Ich nutze sie mit meinen LINSOUL TIN Audio T2 IEM Ohrhörern. Die Verarbeitung wirkt hochwertig, das Design ist kompakt und stört nicht. Die Bedienung ist einfach.... in den USB-C Port stecken und den Ohr- oder Kopfhörer anschliessen. Das war es schon. Für mich ist der KA1 ein echtes Upgrade für meine Kopfhörer.
