i love these buds! sound quality is incredible. i've only ever had the chunky over the ear bluetooth headphones because of the noise cancellation. but these little guys are amazing; and if i want to turn the noise-cancelling off, it's so easy! my biggest and only complaint/problem is that the buds won't stay in my ears - i've changed it to the small ones and they will stay for less than 1hr, then as i'm talking, they fall off. i nearly lost them the first day i used them. when will samsung come out with foam-tip so they don't fall out? that's the only thing i do not like about these buds; and they are so new that there's no one out there that makes foam-tips to fit these.
samsung, help the people out and make foam-tips. some may be allergic to the silicone or like me, just doesn't stay in.
