The earbuds are of very good quality, producing very good sound even at high levels. They are comfortable in use. Sound isolation is only moderate, but there is some useful effect. Be aware that there is no volume control on the earbuds themselves.For most uses they are amazing value for money.For the use I bought them for (in the line-out jack from a TOM TOM GPS on a motorcycle) they weren't the best choice... But I removed the soft silicon ends, drilled a hole in the end of the foam earplugs I always wear on the bike, and zip tied the earplugs on to replace the original ends. This is now exactly what I needed - the ear plug attenuates the (very LOUD) volume from the line-out jack, and also provide the sound isolation I needed. They fit very nicely in my ears under my helmet. And for a very few dollars instead of $100 and up... :D
