Summary: I prefer headphones that do not enter the olfactory canal and these fit the bill for me for receiving long conference calls or making them. Basic, well designed, functional and very inexpensive, I have several secreted in the places I frequent - my car, my office, my bookshelf at home, my study table... Takes rough use and easy to manage. The cables are just right. I only order these for my calls and have stopped using other brands or models.
Summary: Absolutely rubbish. I always thought no matter what, if frequency response was good (18-22000 in this one) headphones should sound good. Well, I was wrong. They literally lack bass, there isn't any bass at all and audio quality is awful. It's ok for answering calls but personally I can't listen music with these. There are other proper brands out there (without mic) about same price.
Summary: It could not work with my Nokia, though its my mistake. But sound quality is very good. Its quite rigid, I felt. Often it get tangled with other stuffs and the way I pull it out, it should not last for long but it is still working awesome. Very nice. Cons: If you put for very long, its uncomfortable.
