I purchased two off these JBL speakers to extend sound from room to room and from inside to outside by the fire during family gatherings. I have planter fasciitis and wide feet. You can also use these wired with the provided two-pole Aux jack. I listen to music and watch videos quite often and I like to sing out loud but don?t like to hear my self. The rubber piece that goes around the ear is very comfortable and fits and adjusts behind the ear great and is very sturdy, as I have gotten others that were very flimsy. I also used this over my glass sunroof w/o any issues. If u have installed the Sony headphones connect app, then the bass issue, some might feel, is also not there. Tried to get them to fit in many ways and theyre just poor design. Fett! I finally had a chance to wear them last week and before I have even finished 9 holes of golf (riding in a cart for most of it) the back elastic had stretched out and my foot then kept sliding off of the back of the shoe.
