First, I really dig the sound these ear buds put out. Second, they are the most comfortable ear buds I have ever tried. No ear fatigue or soreness after 5 hours of mowing my lawn. Speaking of which I use a loud riding mower to mow and these noise canceling ear buds cut out the mower noise 95%. I love them. The only thing I would improve is MORE VOLUME! I love it loud and even though the noise cancelation helps most folks not need to turn the music up, I like volume. Great buds. Oh yeah, my first set became full of ear wax from mowing in the summer with them. The right ear bud became clogged. I sent them back and got a brand new set from Shure! They were awesome! But they did warn me to keep them clean as they would not send me another free set if I clogged them again. I think that's fair!
