Cubilux USB C to SPDIF Transmitter, Unidirectional Type C to Optical Audio Output Adapter with 192KHz/24bit DAC Compatible with MacBook Pro/Air, Laptop, Computer

I bought this Cubilux USB-C to SPDIF transmitter to add an optical output to my devices, and it has worked exactly as I hoped. I use it to connect my iPhone to my Chord Mojo 2, and also my laptop to the Mojo 2, and in both cases the sound quality is very good – clean, detailed and noise-free. Setup is as simple as it gets: plug it into the USB-C port, connect an optical cable to the DAC, and it’s ready to go. No drivers or fiddling with settings were needed in my case. It locks onto the signal reliably and I haven’t had any dropouts or glitches. The build quality feels solid for such a small device, and it’s compact enough to throw in a bag for travel. For anyone who wants to add a proper digital optical output to a phone, tablet or laptop and feed a high-quality DAC like the Mojo 2, this is a very handy little adapter. I’m very pleased with it and happy to recommend it.

works completely as expected. Plug and play on both Windows 11 and Mac without any setup requirements. Sound quality is unaffected with no audible delay. It is abit pricey for what it is, but so far has done the job reliably

Age (mine) caused me to buy this. I listen to Amazon Music on my Hi-Fi via a Wiim Pro Plus streamer. I like the sound but although the controlling App for the Wiim is very good, it is not available on a PC. Using a tablet or phone, I have difficulty reading the screen and prefer to see the Amazon Music site online on the 60 inch TV in my living room. I needed a way of getting the sound from the USB outlet of the mini pc attached to the hi-fi into the optical input of the Wiim to take advantage of its AKG DAC. Should have been simply plug and play using the Cubilux and would have been had the said mini PC been attached to a screen. It isn't. The screen is attached to another mini PC connected to to the TV about 12 ft away. The answer was to control the pc attached to the hi-fi from the pc attached to the TV using Windows 'Remote Desktop'. Confusion on my part about which was the host and which was the receving PC led to 2 or 3 hours of changing and mixing settings before getting it right. The cubilux, completely oblivious and unperturbed by my confusion just worked. The sound is perfect and delivering the promised full 24 bit 192 khz to my hifi via an interface which is fully legible and straightforward. Summation, the Cubilux is simple, straightforward and effective. Me, not so much.

Works fine. No noticeable audio degradation between PS5 and Sennheiser RS175 but I did not expect the HDMI output of the PS5 to cut output to media amp when using it.

Fantastic little USB to SPDIF optic interface. I'm using it with a FOSI Audio DAC-04 Headphone amp, it's currently (the amp) unavailable but the identical looking AIYIMA DAC A2 is. I used to use the USB input for the audio signal but it was limited to 24bit 96kHz whereas the amp is capable of 24bit 192kHz when operating over optical. With the little Cubilux adapter I get the full 24bit/192kHz and sounds great with a pair of Bose headphones. Note you have to go into Sounds/advanced settings for your device to increase it from the default on Windows 10. I have attached some screenshots that show how to do this on Windows 10. Although I have a company laptop that runs Windows 11 I haven't tried it on there (our IT dept are very fussy about unapproved USB devices) but I suspect it will be very similar. I don't know about Chromebook or Apple sorry. I only use it for 2.0 stereo but I think it's great value for money as the sound from my amp is very good. Amazon music has plenty of high bit rate music to enjoy (I pay for my Amazon Prime).

Quality control must be suspect as the device was dead on arrival. Bought it to connect an Nvidia Shield streamer to a Stereo Yamaha R-N602 amplifier. The Nvidia detected it as the default audio output despite but I could not get any audio. The red LED transmitter was however working. I also tried using it with my laptop, selected it as the default audio output, tried different but-rates but again no sound. Cubilux customer service, however, was good. Ordered a Nobsound Douk Audio U2 which worked first time with no fuss whatsoever. Unfortunately, it is an expensive overkill for my application but it works.

Bought for a PC that didn't have optical out. Works just as expected. Easy to install. Sounds good.

Works flawlessly with Raspberry Pi (no driver software to install) to output digital audio to minidisc recorder and also with digital input version of this adaptor for loop-back recording to the Raspberry Pi with Audacity... working well no complaints! =)

Compré este adaptador para conectar mi barra de sonido Sonos Ray al PC y la verdad es que cumple perfectamente con su función. La instalación fue muy sencilla: lo conecté y funcionó al instante, sin necesidad de configuraciones complicadas. La calidad de sonido es excelente, no he notado pérdidas ni interferencias. Se nota que transmite bien la señal y permite aprovechar al máximo la barra de sonido. Además, es un accesorio compacto y ligero, fácil de llevar o guardar. En resumen, un producto práctico, fiable y totalmente recomendable si necesitas una solución para conectar por óptico desde un puerto USB.

Le transmetteur USB C - SPDIF est compatible avec l'iPad. Le son est transmis sans saturation ni coupures.

Hace lo que dice que hace. Transmisión en alta definición.

This wonderful dongle was the perfect solution for listening to lossless, high-res Apple Music in bit-perfect transport to my WiiM Ultra-based sound system. Since I have a newer iPhone with USB-C port and an Apple silicon-based MacBook Air, I am able to hook up my iPhone (set to silent mode) to my WiiM's optical input and play high-res lossless Apple Music directly to my speakers, taking advantage of the WiiM's digital volume control (much finer than the iPhone's 16-step volume control), subwoofer integration, & room correction, and I am able to keep the iPhone charged, AND take advantage of the MacBook's iPhone Mirroring function to remote-control the iPhone/Apple Music from the comfort of my listening position 10 feet away. Awesome an highly recommended!

I'm using this to get digital audio out of a Raspberry Pi and into an SMSL SU-1 dac, and for that purpose it's exactly what I needed. I love how simple it is. I do think it's a tad expensive though, it's about the same price as an HDMI audio extractor which could do the same thing but this is a simpler device.. but whatever it works great. Side note: I've seen some reviews mentioning it doesn't work with Dolby or DTS. Although I haven't tried that, from what I know about optical audio there's really no reason it shouldn't work. It will not transcode your audio into Dolby or DTS though, as in it wont just output all audio that way. The software you're using must support sending those formats over optical audio (such as Kodi), and the file you're attempting to play must contain one of those audio formats. Once the software is configured to pass the audio through optical it should work.
