Simplecom CM423v2 HDMI Audio Extractor 4K HDMI to HDMI and Optical SPDIF + 3.5mm Stereo

HDMI is capable of transmitting both video and audio signals through a single cable. However, in cases where we need to output audio to an external speaker system that has analog or optical input, this audio extractor serves as an ideal solution.

This adapter allows the user to extract the embedded audio from an HDMI source and output it separately through an analog 3.5mm audio jack or a digital optical SPDIF connector. The video stays within the existing HDMI signal and can be sent on to the HDMI display.  

You can easily place this compact adapter behind your AV equipment, and power it through a USB cable that can draw power from either a USB charger or an available USB port on your TV, media player, or PC. It is compliant with both HDMI 1.4b and HDCP 1.4 standards.

Good value for the money.
Size: 9.5 Wide, Color: Beige
Comfortable right out of the box. Great style and well made. The more you wear the softer they get but maintain their overall appearance.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
