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

Working properly with 5.1 system connected to Mac mini M4 pro.

Works as advertised. But overpriced for what it does

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.

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.

Works as intended and is picked up right away by osx.

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.
