They are connected to my Mac studio. You can play multiple systems with these and the sound is amazing. Absolutely no static. Unlike Bluetooth. ### ⭐⭐⭐⭐⭐ Works great *by P***G on July 14, 2026* Works on my iPhone 15 pro max just fine. I was surprised I had zero problems. ### ⭐⭐⭐⭐⭐ Works with Sonos Beam Gen 2 *by S***N on November 5, 2024* I have only had it for a few days and will update if issues happen. Sound wasn't coming from my Beam Gen 2 when using this with the optical to HDMI adapter from my Windows PC, a SPDIF output was showing up in outputs but no sound was coming out, even when plugged into a MBP. I assumed the cable was bad and was going to return it. Before doing that I messed around in the Sonos app for a bit, factory resetting the Beam a few times and re-adding it to the system. I even tried downgrading the Beam to S1, which didn't work and errored out. After re-moving, re-adding and going through the "Pair to TV" option in the app it just suddenly started working. So for anyone having issues getting sound to work with Sonos products, it might just be the app and not the adapter. EDIT: So it turns out it's setting the output to "TV" in sources. ## 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.au/products/408710372-usb-c-spdif-emitter](https://www.desertcart.com.au/products/408710372-usb-c-spdif-emitter) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-08-01*
