Obviously you get them when you want a headset and obviously they don't isolate sounds from the environment if you have two ears (because I see some comments)! Personally, I got them because I want to have a headset to listen to music at work, so I didn't use it for calls. It has a very satisfactory sound, but in three months they have started to lose contact, probably they will break soon. Okay, they cost 5-6 euros, but the lifespan is very short.

They broke in a week........better look for something better!!!!!!!!(the fact that it is 1 in a noisy space is tragic)

For their price, they are amazing, just like if I were buying a more expensive product like these. I highly recommend them without hesitation!
