Love these, will be getting more. ear model sound as good as my Sony MDRXB80BS earbuds. Wasn?t expecting it to be a ?swappable,? so now I have to buy a base in addition to the Popsocket, but I guess I should?ve paid more attention to the description. Truth is I want to get one for myself. No soldering was involved. And so comfortable. Im now regretting not wearing them before the end of July because the return window has already closed. i ordered that size. My clients are always very excited that I have music with me. I wanted to like the slipper but it is cheaply made - it arrived with a defect and not even a month later the rest of the slipper is falling apart.
