I really love mine. They stay in the ears and much more comfortable than the original ones. The sound is far better too with a rich bass sound. I like that they are all one piece with no rubbery tips that can come off like some others I have.
I hate "directional" ear buds...not to sound childish, but who are they to tell me which ear to use them in?!?! I had the same problem with my Beats earbuds...only meant to go in one way. Why not make a left ear version also?
I used them for the first time yesterday during a 4 hr trip to Baltimore. After about an hour I wanted to throw them out the window. They are extremely uncomfortable to me it was brutal to deal with. I miss my old earbuds.
