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

My prior desktop computer had an optical output. With my laptop, no such luck. So I purchased this unit and it worked perfectly right out of the box, no Windows settings required adjustment or configuration. I should add that I actually connected this unit to a docking station that is connected to my laptop and not the laptop itself, and was concerned that this may present a complication but it did not. The computer located the converter right away. The sound quality is excellent in my opinion. I source music to a pretty high end audio setup and there is no background noise or hiss, and no stuttering or other sound issues.

If you want to send audio any other way, you're looking at introducing delay, from a network/wireless setup, or degrading audio quality from converting from digital > analog, then back from analog > digital, not to mention EMI. Keeping the signal all digital like this, and using a hard wired connection, is absolutely the best of both worlds. As long as your sample rate/bit depth is the same across devices, this is the only solution you should be looking at. I used it with a 15ft optical cable, and it transmitted just fine.

I hooked them to 2 sterio systems in 2 different rooms. They are connected to my Mac studio. You can play multiple systems with these and the sound is amazing. Absolutely no static. Unlike Bluetooth.

As far as the physical product itself it seems good overall but the wire doesn't seem that sturdy so I'm concerned how long it will last. The adapter does output dolby digital but does not work for my intended purpose so I'll be keeping it but more for "just in case" purposes. This is in no fault of the product now that I did more research on surround sound/dolby digital. The rest of this review is not related to the product but might help others with the same situation. TLDR - To get surround sound on PC games you need to connect via HDMI or if using toslink/optical a sound card that has dolby/dts encoding I want to get surround sound on my computer for gaming but most games that have surround sound don't have dolby digital. Most PC games that have surround from my understanding are PCM/LPCM multi channel and then a small selection that have Dolby Atmos or dolby digital. Toslink only supports stereo PCM or dolby digital/DTS. Audio over HDMI does support multi channel PCM/LPCM but I'm using a DP monitor so connecting HDMI would make my PC see 2 monitors which has its problems. For my use case to get surround sound from PC games via toslink/optical would require a sound card that has dolby digital or DTS encoding.

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.

Why did you pick this product vs others?: This is rubbish. Purchased this for my Mac to replace an 2.0 optical convert because I wanted 5.1. Not only did never work in 5.1, no matter what kind of source I was playing, but it sounded TERRIBLE. DO NOT BUY.

No issues at all. Plug-and-play and works flawlessly. There’s a soft click when Windows first enables the sound output, but that’s just the receiver syncing — not a fault of the adapter. Clean, stable SPDIF signal.

I use this to connect my work laptop to the third input of my DAC on my audio system. It works, decently well. Plug and play, audio sounds fine, no complaints at first. However once it has been plugged in for an extended period of time, which is only a few days, it will start "resetting" for lack of a better word. Whenever it is not playing audio it will stop sending signal to the DAC entirely, which causes the DAC to stop seeing it as a source. So latency is added. Play am audio file? This will 'wake up' and start playing but not after missing the first few moments of the audio. This happens for notifications. Music. Videos. Anything that outputs audio. And as soon as the audio is done, this will stop sending signal again entirely, dropping off the DAC again. And if your DAC has a source switch relay like mine does letting it do this can wear it out mechanically as well. You have to unplug the adapter and plug it back in to get it to stop doing this. Which, for what should be a plug and forget solution, makes this a really subpar experience for me.

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 Amazon 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.

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.

Prima compact product! 44.1 16bit in Fedora 44 geen enkel probleem!

Schnelle Lieferung, anstecken und funktioniert sofort ...👍

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.
