Review: Great little USB-C to optical adapter – perfect with Chord Mojo 2 - 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.
Review: Simple plug and play USB C to optical adapter - 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

### ⭐⭐⭐⭐⭐ Cubilux works perfectly and performs as promised.
*by A***R on 25 December 2025*

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.
