Summary: Have not used them yet, but I originally bought Maxwell earbuds at the local Walmart which did carry the Koss brand. I returned the Maxwell earbuds. The earbuds did fit comfortably and the wire was a foot shorter than the Koss brand. I went on -line to purchase the Koss brand which has served me satisfactorily somewhere around 15 years. I suggest removing Maxwell earbuds from the stores proper and returning Koss to the shelves.
Summary: Handy and easy to use. Only drawback is that if inserted into the ear it can be very uncomfortable. I just hang it lightly on the edge of my ear and it works fine. Of course, that only works if I remain sitting.
Summary: The problem with these ear buds is that they are so big that they don't want to go in your ears. Once they are in they promptly want to fall out. This is what is wrong with the sound quality. When they are all the way in the ear, they sound ok. But since they will not stay there, most of the time it is impossible to hear anything with them. I am returning mine. I have used Maxell earbuds in the past. While not perfect, the Maxells were much better than these.
Summary: These are not the most comfortable headphones, particularly if you compared them to the old apple earphones. Nevertheless, the sound quality is good; though I cannot speak on the longevity since I have only had the product for about a week. Note that the ear plugs are not rubberized and they are slightly large, which maybe important if you have small ears. Besides the slight hiccup in comfort, I would recommend them as budge ear phones.
