I have purchased many, many pair of Fit Flop shoes/sandals & this may very well be my favorite pair yet! Its a fine boom arm. Like the original, it blocks outside sound more than the average IEM. I bought a few different ones since I needed several, and this is definitely the one I like best. 99 ??, these were on sale Im not sure how much they usually are but Im sure they are under $20. I love this phone so much. Now I am a bigger guy and I am capable of some serious torque. Very sturdy and stay on well. Why give away $600-$1200(or more) in rack assemblies when you sell your vehicle vs keeping it for your next vehicle. Shouldnt have been surprised to discover how incredibly comfortable these are.
