Review on 🎧 Economical Single-Side Mono Earbuds: Noise Isolating In-Ear Headphone with Reinforced Cord by Lan Rosales

I expected this single headphone to combine left and right sound into one audio output. But actually it only outputs the left side of the stereo sound and just skips the right side. When you hear California Dreamin', all you hear are the mamas singing; You don't hear dad. upset. Probably good for podcasts or maybe modern music recordings where left and right mixes aren't that different.
