My opinion about Sony MDR ZX110 is they are the best budget headphones of Sony with top-class sound. Clear vocals, great bass, and balanced sound with low sound distortion.

While they may not have a design almost as solid as that of the Panasonic Headphones RP-HT161-K, or be wireless like the Mpow 059, the Sony MDR ZX110 offers you a great sound quality with a great amount of focus on bass packed into a build with durable wires and a pretty comfortable ear padding. And, so if you’ve just got a few bucks to spare and you need a headphone to just get by during your commute or you need a temporary urgently, the Sony MDR ZX110 should be your go-to at a price almost as low as $7.

They feel cheaply built and poorly isolate listeners from ambient noise. They're a low budget pair for casual listening or recording thanks to their low leakage but lack too many features to be versatile enough for all use cases.

Still, you can forget about details and small nuances in vocals. But for casual listening, the Sony MDR-ZX110 offer excellent value.
