Review on Sony MDR-ZX310AP ZX Series Blue Wired On Ear Headphones with Mic: Immersive Sound Experience by Minoru Korishige ᠌

Soundproofing is average, but for me personally, in certain circumstances, this is a plus, I was looking for such - not like sitting in a cellar, but to be able to hear what they are starting to talk to you Pros: They were used (in my opinion) for a long time - the right earpiece went haywire after 2 years and 2 months. Foldable is a plus Some cons: The microphone is so-so; to be heard normally, you need to either speak very loudly, or bring the microphone close to your speech apparatus
