I purchased one new Jbl extreme a couple of months ago. On an impulse and careful review reading, I got these. Everything you want in wireless earbuds. He says they are comfortable and he very happy with them. I own a Copenhagen and a Oslo and both are espectacular. But overal it does the job, for charging multiple devices, I usually just used it for overnight charges when travelling. If you looking for old school simple flat shoes try AAdidas Originals Mens Seeley Running Shoe, and PUMA Mens Suede Classic + Sneaker for similar style and cooler comfort. No only that, but the fact that the fabric straps are hold by the flimsy metal bars, this makes it for a very uncomfortable process of assembly. However these are just awful. After they receive the product back, they say they need a support ticket number from Jabra in order to return it and that they will send it back to you at your expense, etc.
