Terrible speakers and poor product design ergonomics. 2 of these were purchased and they were of different lengths, when they should all be the same size . The large one slides right off my head, and I have very big dreadlocks... i bought it on sale and I still kind if feel ripped off. Need to take it back to the drawing board and make a 2.0 version with more thought out design elements. And for the love of God put better speakers in it if you are charging $150. Ridiculous.
