Review: Does it’s job - 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.
Review: The best way to send audio from one PC to antoher. - 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.

## 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 to enjoy 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 can output stereo optical signal without any setup or software, and with a media player to decode 5.1 files and proper setting, it can output 5.1 surround sound, but this adapter does NOT support 7.1 surround sound due to the limitation of the USB port.
- [NOT for Partial-Featured USB Port] – This adapter is designed for computers and is not compatible with devices that devices with only partial-featured USB ports, such as TVs, Car USB ports, speakers’ USB ports, etc.
- [Crystal Clean Hi-Res Sound] – The USB Type C to TOSLINK Connector delivers crisp and clear sound from 48 KHz/24-bit to 192 KHz/24-bit with great clarity and rich audio details.

### ⭐⭐⭐⭐⭐ The best way to send audio from one PC to antoher.

### ⭐⭐⭐⭐⭐ This 100% works sending hi-res Apple Music to your DAC
*by T***E on July 23, 2025*

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?
