Good replacement for portable headphones

I did not buy it for loud music, just to replace the headphones from my laptop while I watch filmes. And for that, that's fine, the sound is much louder than the notebook, and therefore less saturated, which allows me to better understand what is said. I also use it to replace the integrated earphones of my screen.
The enclosure is very small and easy to carry. My laptop has a USB input next to his jack, so I plug both very quickly and I sound like I have to.
I bought it at ~ 15 (flash sale), and that price is certainly a good deal.
