A good headset for the cost. (knowing how well it worked). The height adjustment pieces sit inside little notches that are out of the base. Runs large for a toddler girl and not glittery. Very awesome! This happens over and over and I still cannot get the speaker to work. I got these for the purported noise-isolating benefits of the in-ear buds because I was having to turn the volume up too much on my AirPods while in the gym to overpower their sound system. Extended or retracted, mute button on or off. The mic also doesnt work. I really like the AirPods charger because I was always forced to remove the case in order to plug it in.
