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.

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 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! =)

Great little device that saved me having to buy a new soundbar for my PC as it only accepted an SPDIF optical input. This device goes from the PCs USB-C port and creates an SPDIF optical input so you can add your cable from the soundbar to the PC. Works as intended, great sound quality.

I had previously bought the USB C version for use with my PS5, but had to return it due to the audio keep cutting out. I then saw the description for this one (USB A) which said it was compatible with the PS5, so thought I'd take a chance. However, upon trying it, yet again the audio kept cutting out exactly as the first one did. So this is definitely NOT PS5 compatible, not unless I got extremely unlucky with 2 faulty products from the same company. Just incase it wasn't the adapter at fault, thinking maybe it could be my toslink cable or my DAC, I decided to try connecting my cable and DAC to another source without using the adapter, and the audio was perfect, so definitely the adapter at fault. Personally I would not recommend this product, but you are welcome to try.

Excellent optical link, I’m using it to output from my pc receiver , 5.1 out out for movies , easy to install and great value

Works really well for computers that have no built-in digital/optical output. I praise the product because it turns the optical connection output of when nothing is playing; this is useful for receivers, like sound bars, that can turn themselves on and off automatically using signal detection. No special drivers are needed, you just plug it in, and it does what it's advertised to do. Wha you will want to do manual is set the bitrate and frequency in your computer's settings to a config supported by the receiving device as well as set it as the "default device" if other audio devices/outputs are available. The cable is a little on the thin side, but I'm not docking any points for that because, as with any other digital product, it'll last if looked after. I'm using this product with a Dell OptiPlex 3000 Micro (2022 model), which is serving as part of a bedroom theatre system; it has no rear output audio port at all, so it's a perfect fit! I have mine configured for 24-bit @ 48kHz, and the sound is just pure bliss... you just can't ask for more. If you're looking into moving away from copper cables because of signal crosstalk or residual hissing noise, this product is one great way to make that transition.

I bought this as a way to get lossless audio from my iPad, iPhone and windows laptop to my HiFi and this works almost flawlessly. When steaming music the quality is amazing, no issues at all and audibly better quality than Bluetooth. YouTube and Netflix also work great, but when streaming video using the Apple TV app no audio comes through (using Windows and iPad apps). Luckily this isn't a dealbreaker for me (and also is likely Apple's fault rather than the manufacturer, since it works with other streaming services, hence I haven't docked any stars) but I would look for another product if playing back Apple TV content from a laptop or iPad will be important for you.

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.

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.

Excellent little device at a great price. It acts as a USB Audio Class 2 device. Plug it into USB on a computer, phone or tablet (including via a Lightning adaptor on iPad/iPhone), and you get out optical audio, suitable for many items of audio equipment. I tested it thoroughly. It provides bit perfect performance on CD-standard digital audio -- 44.1kHz -- and also supports 48kHz, 96kHz and 192kHz, 16 and 24 bits. It does NOT support 88.2kHz or 176.4kHz. These are relatively rare, but do exist. Your device will convert them to 96kHz or 192kHz. Formats as shown in image. In 99.9% of use cases, though, the gadget it great.
