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.

Using optical out with a Chord Mojo 2. Works great.

Ideal for MacOS. I get 24 bit/192 kHz audio out from USB C to Toslink for a very cheap price, so this is great value. As it's just in a cable-size format, it's compact, it's easy to connect, and so far now - several months - it seems there's little to go wrong, so I'm content with the build quality. The step up from analogue to 24/192 digital audio - including Dolby Atmos from Apple Music - is astonishing.

Very pleasantly surprised. I have only had it a couple of days so I cannot comment on its longevity but it does actually work. Its installed between a Mac Air M4 and a Yamaha 501 amp. It also works on my Teac DAC but as it has a single output rate only, its actually a better sound using the shortest path direct to the amps optical input. The sound lacks depth but that can be fiddled out to some extent and given my computer library is mostly old recordings that are not always CD quality that does not really matter. Stereo definition is also definitely there. All in all a great solution assuming it lasts and is well worth the £21 quid it cost. Problem is most buyers will, like me, be audiophiles and will expect it to be perfect which is not But is does solve the drop out issues that M series Mac users are experiencing with even the best DACS that don't have native usb c. And i.t also works perfectly well with the computer set to low power.

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.

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.

Does exactly what it says. Outputs S/PDIF digital 2 channel PCM audio at up to 24-bit 192khz. Easy to connect. Cable attached to it seems a little flimsy and it isn;t very long so I avoid putting strain on it, I never let it dangle. But because it is so short it usually sits next to my laptop on my desk, and I use a longer SPDIF cable to my DAC or receiver. But if you have a desktop with high up USB sockets, I would recommend connecting a USB C extension cable to this, so the usb cable end doesn't dangle. This is good value for money though. So simple yet some sound cards which do the same thing cost upwards of £70.

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).

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.

Werkt probleemloos, geen stroom nodig.

Was looking for a connector from my MacBook Air which has 2 USB-C output. My WiiM Amp Pro does not support USB input but it has TOSLINK. So, thank to the maker of this product so I can play any music source - watching YouTube, listening to music library and conference Zoom calls. Package well packed decently.

Funciona muiito bem

Miracoloso!!! A parte gli scherzi ho risolto l'annoso problema che affligge l’audio dei computer Apple che, dal 2016, non possiedono più l’uscita del Connettore Ottico per l’audio digitale che permetteva BitRate ad alta risoluzione. Le uscite USBa e USBc/Thunderbolt dei Mac dal 2016 in poi, infatti, non supportano audio in uscita con un BitRate maggiore di 16/44 Khz, precludendo agli appassionati di musica tutti i brani ad altissima risoluzione (es. 24/96Khz oppure 24/192Khz) disponibili da più fonti. Sono possessore di un un MacMini 2018 col quale ascolto musica "liquida”, pilotando un DAC Maverick Audio D1 fornito di 1 entrata USB e 1 entrata SPDIF Ottica, entrambe con capacità di BitRate di 24/96 Khz. Anche questo MacMini, quindi, essendo costruito dopo il 2016, non possiede alcuna uscita Ottica Digitale ma solo USBa e USBc/Thunderbolt con le quali posso trasmettere l’audio all’entrata USB del mio DAC ma, come prima affermato, solo con un BitRate massimo di 16/44Khz, al di sotto delle capacità del mio DAC. Con questo adattatore, collegato a una presa USBc del Mac, posso alimentare senza alcun problema l’entrata Ottica del Maverick con un BitRate ad Alta Risoluzione di 24/96Khz. Allo scopo ho utilizzato un buon cavo SPDIF Ottico (non fornito assieme all'adattatore). Appena collegato l'adattatore alla presa USBc del MacMini 2018 da una parte e, dall'altra, alla presa Ottica del DAC, ho aperto l’App. “Configurazione Midi Audio” (che si trova dentro la cartella Applicazioni > Utility) dove ho trovato elencato, assieme alle altre periferiche, l’adattatore Cubilux col nome "USB SPDIF Adapter". Selezionandolo ho potuto modificare il BitRate di uscita andando oltre a quello che prima veniva consentito da una "normale" presa USB di qualsiasi tipo (vedi immagine allegata). Il passo successivo è stato quello di ascoltare la mia musica preferita ad alta risoluzione utilizzando un applicazione dedicata (es.FooBar 2000, Audirvana, ecc). Ottimo prodotto, costruzione di qualità, non invasivo e con un prezzo abbastanza abbordabile considerando che risolve un problema che affligge numerosissimi utenti appassionati di Musica che utilizzano Mac costruiti dopo il 2016. Cinque Stelle meritatissime.
