USB C SPDIF Emitter

Works just as I expected but my iPhone 15 didn’t. Hoping to use the transmitter to connect the iPhone to my stereo’s SPDIF input I found the phone stuttered (jitter perhaps) every few seconds making it unlistenable. I’ll buy another Cubilux adapter when the need arises.

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.

This 100% works if you want to send Apple Music native digital hi-res music to your DAC. I’m using an iPhone 15 and have the adapter connected to the optical-in on my Oppo BDP-105. Sound quality is great. If you notice any dropouts just download the file to your playlist instead of just streaming. Attached photos of the hi-res file playing on my phone and the readout from the Oppo on the bit rate. Now if we can only get a search filter for all hi-res lossless albums on Apple Music. Who wants to work on this?

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.

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 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.

You can’t stream hires lossless (today) so need a wired connection. AppleTV is limited to 48 kHz. My AVR has an internal DAC that supports 24b / 192 kHz but won’t accept via USB. Looked all around for solution because I knew it had to be simple. And it is but everyone only suggested external DAC. This dongle lets you connect directly from iPad or new iPhones using an optical cable. I tried both and works perfectly. Sound quality is noticeably better if you have other good components like amp and speakers. iPad makes nice music display too, just need to figure out way to control remotely.

Le transmetteur USB C - SPDIF est compatible avec l'iPad. Le son est transmis sans saturation ni coupures.

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.

Perfectamente compatible con mi Oneplus Nord 2t y la cadena de música Panasonic 802PMX. Escucho música Hi-res en la plataforma Qobuz. La diferencia entre el cable y el Bluetooth es notable.

El adaptador sirve correctamente, arroja audio codificado si tu reproductor y contenido te lo permite, lo he probado con un sistema 5.1 Logitech z906 usando una macbook pro, es plug and play, solo conectas, seleccionas la salida de audio en las configuraciones de sonido y listo.

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