I needed to replace some old Skull Candy bluetooth headphones; I went for this JBL model needing something that would fit the bill when it comes to maintaining music whilst exercising. These don't fall out, they don't move around, they're sweat resistant. They have great bass, and the JBL companion app provides additional features to customize your EQ any way you please to get the right fit for your sound. Intuitive pairing functions mean they instantly connect when you put them in your ears. Admittedly they are a little bulky especially if you are used to in-ear buds of any kind. That said, this is an upgrade I am extremely happy with. Excellent battery life to boot, and a handy little storage case to keep them clean and protected. Note there are a few odd artefacts that pop in sometimes when you change songs, pause, or when a song naturally ends. It's not consistent by any means, quite rare, but something that can surprise you from time to time. Overall, pleased with the product for the price I paid, certainly one of the better performing models of bluetooth headphones for fitness-minded people but equally great sitting at a busy desk.
