The cubilux usb optical interface's material feels more premium than its price would suggest. This adapter is super portable to carry. It works well for a sonos ray sound bar. It shows up as a headphone and the audio is different than that coming from an audio extractor, which is designed to be for speakers. It works well for windows, mac os and linux computer, laptop, pc with usb type port and ps4/ps5 gaming console.

This will look like a DAC and have no volume control. The cord is a nice braided material. The adapter isolates em / rf interference and offers great durability as well.

Best With Coaxial Output: Douk Audio USB Optical Interface

Buy on Amazon

We would, of course, be remiss if we didn't mention douk audio usb optical interface for daily purpose. This device is a must have for people who have interest in getting the most from what they have. It can be used as signal input and power input at the same time, and with external dc 5v input (with priority) that can be powered by phone charger or power bank, easy to enjoy hifi music any time and anywhere. The Douk can play up to 196 kHz audio using the optical/coaxial port. This way the relay will stay engaged.

The parts selection of the internal components is superb. It is compatible with 32/64 bit 710 systems (needs driver), mac os 10.6 and native linux with uac2 (no driver needed), and android with otg function. This converter is very small so they would have to move the HDMI and external 5V input port to the side. There is a blue light on it when getting power.
