Plug n Play! - I purchased this as a (hopefully) cheap way to upgrade my audio across the board with the intention to use the SPDIF with my Fiio E17 portable DAC/Amp which contains an Optical connection via an adapter which it came with. So I figured instead of using the 3.5mm connector to pipe my audio through why not get this and use USB audio and convert it to clean Optical - and it works perfectly plug and play with my phone/tablet and my Steam Deck and on PS5 you just have to use the front USB C port switch to the SPDIF converter (oddly enough not the DAC) and it works and sounds fantastic! No bluetooth either which means no audio lag or loss of quality. So this converting USB audio to clean Optical via a DAC/Amp combo using Quobuz bit perfect mode or desertcart Music Ultra HD tracks wow! Movies sound fantastic too. As do games. Delighted with this product. Its a lot smaller than it looks too Might try and get a small Optical cable to cut down on the wires making it more portable. 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. ## Features - [Convert USB Port to SPDIF Transmitter] – Cubilux S/PDIF Output Adapter lets you transmit the optical audio signal from the USB Type C port of computers to soundbars, home audio system, external DAC or amplifier with optical inputs to enjoy stereo or compatible 5.1 surround sound. - [For Output ONLY] – This converter cannot be used in the opposite direction, not for receiving SPDIF signals from source devices like DACs/AMPs, not for recording audio. - [Support 5.1 & Stereo Audio, NOT for 7.1] – This adapter outputs stereo optical audio.

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. ## Frequently Bought Together - Cubilux USB C to SPDIF Transmitter, Unidirectional Type C to Optical Audio Output Adapter with 192KHz/24bit DAC for MacBook Pro/Air, Laptop, Computer - KabelDirekt Optical Audio Cable – 10ft Digital Optical Cable for soundbars, Fiber Optic Lead (Digital S/PDIF Cable, Stereo Systems/amplifiers/amps, Home Cinema, Xbox One/PS4) - Cubilux USB A to TOSLINK Optical Audio Adapter, Unidirectional USB Type A to SPDIF Digital Converter, S/PDIF Transmitter for Computer Laptop PC ONLY, NOT for TV Or Other Devices --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/433711219-cubilux-usb-c-to-toslink-optical-spdif-output-adapter-192](https://www.desertcart.com.cy/products/433711219-cubilux-usb-c-to-toslink-optical-spdif-output-adapter-192) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-11-04*
