Update 01/31/2018: More options! I can imagine the more I listen, the better theyre going to sound. I bought a 9 for my last pair because that was my only option. seems of but I think Sony uses softer plastic with their plastic O-rings and are not molded the same as the originals. It is unfortunate but oh well. If it wasnt for him, I would have returned it. I put them on and instantly they were so comfortable I never wanted to take them off. It is lightweight and easy to install. Tip: to widen the mount for your phone, slide it inwards and hold while you unscrew it. Love, love, love the color combo!
