"Uncomfortable, doesn't stay on my ear, but nice sound"2.0 starson by aipinquan
Pros: Great sound.
Nice form factor.
Cons: Clumsy to put on.
Horrible ear cups that do not stay in my ear.
Summary: What good is great sound when the earpiece pops out of my ear after 5 minutes? My PLT510 was wonderful. How could they lose so much functionality in this design? The limited options for earpieces mean I cannot find one that will work at all in both ears, and I can't find one that stays in either ear. And don't even go to their site to try to give them feedback unless you want to punish yourself.
