Very good construction and sound quality. I use them for several hours and they don't bother me at all. They are lightweight and comfortable.

I bought the SENNHEISER PC-3 Chat Headset for teleconferences via Skype, Zoom, Messenger, and I am completely satisfied. It does exactly what it promises and what you expect from the quality of SENNHEISER. Simple and lightweight construction but not cheap. Very good sound for this specific use at least, very convenient microphone, good noise isolation, no complaints from my listeners. Its major advantages are the proper and discreet design that embraces the head without looking bulky and its very light weight that doesn't tire at all even after hours of use.

It's not something crazy in terms of construction. They could definitely be cheaper. If you work from home and need to wear headphones with a microphone to work, it's okay. But that's about it, the sound from the headphones leaks out, so people around you can hear what you're listening to, and the microphone is just decent without anything amazing.

Today I completed 4 years with these headphones. The only thing I changed is the ear cushions due to wear (for 1.5€) 2 months ago. Good sound, average bass, good microphone, and lightweight on the head. You can now get much better features for the same money, but you won't find such durable headphones no matter how hard you look.
