DMS Open Omega Mini XLR Version

I made a mini XLR version of the DMS Open Image headphones. The original headphones have a 3.5 mm jack on both sides, but I prefer to have only one cable on the left. Disclaimer: I'm not an expert in audio engineering, so I'm not 100% sure if there is any loss of audio quality compared to the original ones. I changed the left and right cups. I added a bigger threaded hole for the mini XLR connector to the left cup and closed the hole on the right cup. I added a hole to the top back of both cups for the cable between the left and right cups. i used this Mini XLR connector
