Review on PROZOR 192KHz Digital to Analog Audio Converter: Volume Adjustable Optical to RCA with USB Power - SPDIF TOSLINK to Stereo L/R & 3.5mm Jack DAC Converter by Walter Martin

Nicely made, nice form factor and it works. I like to use Audio Technica headphones when watching music videos and movies on my 4K TV. Unfortunately, most new TVs have optical audio and RCA audio output but no longer have a 3.5mm jack. Sign up with this handy device. The Prozor DAC allows you to connect your TV's optical audio output to this device using the supplied male-to-male cable that connects to the DAC. You can then connect the 3.5mm mini plug directly to the DAC and adjust the volume with the knob. It sounds great. You can also plug a 3.5mm plug into a full-size headphone audio jack, as is often the case with high-end headphones. This device has enough power to fully support full audio jacks, thicker cables, and more powerful headphones or speakers. Just a great solution! The audio, despite being switched from digital to analog, is still excellent; for general listening of course. Furthermore, you can additionally use this device to convert the digital/optical output to RCA if your TV does not already have RCA audio outputs. This is handy for connecting your TV to a powerful external speaker that isn't designed for a TV. The device is small, made of aluminum and has a good build quality. One note is that no power adapter is included. However, I used the included USB-C to USB cable to draw power directly from the USB socket on the back of the TV. I highly recommend this device!
