They worked fairly well at first, then developed issues with dropping connection from my phone, strange random beeps... then almost three months to the date that I bought them, they're completely dead.

There is an *extremely* annoying, loud beep that happens when you hit max/min volume

This beep is redundant-- I can figure out when I hit max/min volume on my own, I can set my own max volume on my phone, and I don't need a loud beep to know when I've muted
