Review: Había leído reseñas sobre este que si es un buen dac solo que al inicio solo se podía comprar en la pagina de Razer pero no mandan a Mexico. Me esperé, esperando que algún dia lo pongan en desertcart para vender. Y lo vi y lo compré. Aquí es mas barato con respecto a la tienda de Razer. La verdad si ayuda a mejorar el audio de youtube, spotify, si es que tenes archivos en mp3 tambien los mejora. Ya si tienes Tidal o un servicio de streaming de musica con calidad premium se escucha muy bien.
Review: Tl;Dr: Great portable amp and DAC. Makes any pair of headphones sound even better, but it eats up battery life like crazy on your cell phone. A more in depth review: I originally got the Razer THX Onyx to pair with my KZ zs10 Pro IEM's (in ear monitors) because I wanted something that can take advantage of the full range that those earbuds offer (7hz-40khz). The THX Onyx did not disappoint at all, especially with a sound range to match (10hz-40khz). Both go beyond the normal sound range the average human can hear. Because of that it definitely enhances the sub bass range and adds more punch and "feel" to music that is bass dominant like "Barbie Dreams" by Nikki Manaj or "Freaks of the Industry" by Digital Underground. Mids and highs sound just as wonderful. Listening to jazz or blues, you can hear all the subtle nuances In a raspy voice or the crash of the cymbals. Listening to an artist like Massive Attack sounds really good. Because of the zs10 Pro's low impedance (24ohms), I had to turn the volume down by almost 1/2 of my normal listening volume. The amplifier in the THX Onyx is wonderful. I tried it with a pair of generic earbuds and they made those sound even louder too. Lastly, I tried it with my wife's Razer Kraken headphones because those are notoriously low sounding when using them with a cell phone. It definitely brought the volume up considerably for those. The DAC circuit decodes at higher sampling rates (32bit/384khz) then just your average USB C to 3.5mm adapter (24bit/96khz). Listening to Master Tracks on Tidal opens up a fuller range of sound to enjoy. Unfortunately Tidal's Master Tracks are not encoded that high (32bit), So although they are MQA certified, it is still at the lower 24bit level. So I have yet to enjoy the THX Onyx to its fullest extent with true MQA sound files. My one and only problem with the THX Onyx is that it eats up the battery life on my cell phone rather quickly when it's plugged in, even if I am not listening to any music. On my Google Pixel 6, I can literally watch the battery percentage drop at a rate of 1% approximately every 2 minutes. If I am watching a movie, which this is absolutely wonderful for, and start off with a full charge, my battery is around 50% when the movie is finished. That prevents me from binge watching any series unless I have a USB C splitter which I have yet to find out if it would even work with the THX Onyx and have my phone plugged in charging. To be fair, I tried it with my wife's OnePlus 9 and my daughter's Galaxy S21. Both had the same high battery drain while using the THX Onyx. It is to be expected though when using a portable amplifier/DAC that draws its power off of the USB port. Plugged into a computer, it would not be a problem at all since a computer it's usually plugged in. I have not checked the battery drainage on a laptop that is unplugged from its power supply. All in all, it is a great and wonderful addition to anyone needing a portable amplifier/DAC. A little pricey for some people but it is still less expensive than some other portable high end amplifier/DAC's out there, not to mention the frequency range it encompasses.

*by P***L on 7 April 2022*

Like the title say, I've been using the dac with the akg earbuds that came with my note 9 about 4 years ago and the sound is amazing, feel like a new pair of headphones. I tried the same song with the buds connected directly in audio jack and then through the razer dac and the différence is staggering. This usb c dac makes the audio on my phone so much better, can't listen to anything without it now. I'm not a pro audiophile now so I can't really tell how it compares to other brand, but it definitely works. The only downside is that the volume and play/pause controls on the headphones don't seem to work anymore. The microphone works well tho. Tried only on android.
