I recently bought a pair of Sennheiser PC 37X's but when they arrived I realized that my laptop didn't have a mic jack so I bought this https://www.amazon.com/Kingtop-Adap...on/dp/B01I3A47I4?ref_=bl_dp_s_web_17047881011 adapter. But when I tried plugging it in only the headphones worked correctly. The mic wasn't even detected as being plugged in. Any help is welcome.
