Hi Seifah, to answer your question, I recently bought these and the sound quality is pretty good. It's not mind-blowing good but it is a step up from it's predecessor, the buds plus. The fit I find is very comfortable , and hurt way less than the buds after a long duration. However every ear is different but our of all the products Samsung has I think these headphones have the biggest potential to fit your ears like they did mine with their small size and adjustable rubber holders.
