I don't often leave reviews but I'm mad enough at this product that I decided to leave a review. I mainly only use this adapter when I'm flying/traveling so that I can use my headphones/earbuds with my phone, and sometimes while I clean around the house so that I can listen to music on my headphones using my phone. I've owned this for 9 months now, maybe used it fewer than 3 dozen times in that period (though, to be fair, it would occasionally get moved around on my desk as I put stuff, and it traveled in my backpack from home to the airport, from the airport to my hotel, and reverse), and just yesterday, while cleaning around the house, I realized that the sound was cutting in and out on the right ear of the headphones. I tried it with a different audio device, some Apple earbuds that have worked perfectly in the past, and they had the same issue. It basically feels like I just paid to fill the planet with more broken plastic junk. Do not buy. It did seem to work well with the low resistance earbuds/headphones I used it with when it was working, but I can't recommend this product.

SOUND QUALITY:I use IEM's when I listen to music on my phone, they are very sensitive to distortion. This DAC has no distortion. There is no audible background hiss on this DAC, unlike the two other DAC dongles I own. In comparison, Samsung's DAC has background hiss when used with my IEM's. This DAC gets very loud with my IEM's. If I push it LOUD I can begin to hear distortion in the lower mid range to mid range, but this is pushing the hearing safe limit so its a moot point. This has excellent sound quality that rivals larger DACs like the moondrop dawn pro.COMFORT AND QUALITY:This DAC dongle feels significantly higher quality and looks better than the Samsung DAC dongle. The cable is braided and is reinforced on each terminal end to prevent fraying. Both housings are made of aluminum, it feels and looks great compared to the cheap plastic used in most DAC dongles. The tolerances of both terminals are perfect, snug but not too snug.

The sound quality was great while it lasted. It broke within a few months of use. Maybe I can say that I handled it a but rough but the build quality said otherwise.

i've had problems with the connection of this device. i am using a dongle (that came with it) to plug into a usb-a port. i am not sure if this is the point of failure, but often times it seems like it's not connected firmly to the computer and thus not recognized until i wiggle it or unplug/re-plug it a few times. i am not sure where the point of failure is, but it's unreliable (at least with the unit i got).

soy un audiofilo restaurador y ya he pasado por varios DACs buenos....este esta un poco raro... funciona bastante bien como previo de amplificador y ha de sacar señal con cerca de 2V... un celular lo hace a 0.7V... como previo el, balance de sonido es bueno pero lo agudos naturales y medios agudos son un poco duros, realmente no me parece que haya mayor cantidad sino que suenan un poco "digitalones" pero hace que bocinas con curva de "V" se balanceen un poco... VS lo que hay en una computadora este da un sonido mas limpio, neutro, mejor control de bajo y agudos un poco mejor definidos a costa de sonar un poco digital (en sonido yo creo que es su punto flaco, el apple dongle suena un poco mas "natural" pero de igual modo a veces se lleva bien con ciertos audífonos como los sennheiser) y en general la respuesta en agudos y bajo es simplemente mucho mejor y VS el apple dongle también es mejor pero discretamentecomo puro amplificador tiene bastante galleta y es compatible con android, IOS y windows, seguro con el macOS también el único problema que no se si sera defecto del mio es que a veces si se escucha un poco de "jitter" o bucle de tierra yo creo que debe ser un falso o algo así, por que a veces lo hace y a veces no... esto se nota mas en audífonos de alta eficiencia y baja impedancia (ojo no son distorsiones como tal, es como algún tipo de ruido) en android me levanta unos audífonos KOSS vintage de 100ohms y los levanta muy bien, logrando un volumen satisfactorio y aun faltandole poquito para llegar al 100 de volumenojo eeeh, que cualquier DAC mas serio va a ser superior, especialmente en términos de calidad de sonido pero en galleta se defiende MUY bien

Really incredible sound quality for the money and far better than the built in DAC on any of my devices. I have a dragonfly black ($170) [currently misplaced somehwere in the house.. hence ths order] and an AudioEngine D1 ($229). and besides the considerably higher headphone amp voltage output... there really isn't a dramatic different in sound quality.. none that my peasant untrained ears can pick up at least haha. $20 well spent!P.S. Headphones are Bowers Wilkins P7s (around 10 years old and still kicking ass)

Me gusta que casi no se calienta inclusive después de un uso moderado si lo comparo con un dac de mayor precio, arroja un buen sonido , bastante aceptable para ser un dac de entrada, la APK de UAPP lo reconoce inmediatamente y entrega un sonido mejor que el que da la entrada normal del celular.

Okay first off these little dongle Dacs aren't my favorite because of the stress it puts on the USB-C port, I prefer one that attaches itself to the device like the Syba Dac that snaps onto any device, but with that said this is the 5th Dac I've tried and so far the second best, sound quality is good, seems like it increases the highs and mids but not the bass and trust me I'm running all Dacs to a pair of SkullCandy Crusher Evo's so bass is what I'm looking for (try Eminems Despicable Freestyle, the bass makes my eardrums bleed, lol) especially with my LG V20 ESS Quad Dac 32bit, best with bass that I've come across and cheaper than half the Dacs available (can get a refurbished V20 for $60-$75), so with that said I've tried Realtek, Technics, Qualcomm, ESS and this Conexant chips and for the price well worth it if your looking for an inexpensive Dac/headphone amp, and yes I am a music junkie who listens to music all day every day so I spend alot of time with these Dacs and that's how I rank them, I'm gonna continue trying more out along the way and see how many different chips I can come across, will update if I get any more.

This dac is the best for android out of all that I've tried, with clear audio and volume, EXCEPT for an occasional buzzing I got on my left ear when audio was playing on my Pixel 6, which I wouldn't get on other dacs.I couldn't find any other reviews that mentioned this, so I thought hey, maybe I got a bad unit.So I returned it and got a new one. Same problem. I returned it again and got a new one. Same problem.I tried 3 units and they all had the same problem, so I'm concluding that this is a design flaw, maybe because of some signal interference from the device.I'm still going to use this until I can find a better one, since this seems like the only dac on amazon that can produce decent sound.(The only other dac that had good audio was the apple dongle, but that one has volume issues on android, and has a terrible cable.)

Definitely pushes on the brighter side but for the price and how well it seems to drive my dt770 pro's I'm very impressed. This isn't a basshead DAC, be forewarned about that. However if you listen to more treble heavy stuff I can't recommend this enough. For the price, build quality, and performance, you should skip that Fiio for now and try this. It is a great budget audiophile DAC/Adapter.

Compared to the Apple USB-C dongle, this one has more clarity (mids and highs are more forward) and with slightly more extended bass. It just sounds more full overall compared to Apple. It can drive my DT770 and Drop 6XX without an amp, but you need to crank the volume up past 70%. It sounds best with a headphone amp (I alternate between both a Topping NX2 and JDS Labs Atom+). Build quality looks good (time will tell). No background hiss. Definitely worth the money.Update: I've re-purposed this as the USB DAC to my Raspberry Pi4 and it works flawlessly (Linux recognizes it as "TTGK Technology". This is a must-have sound upgrade to the Raspberry Pi.
