The Samsung U Flex are decently well made wireless headphones. They look more premium than the Level U Pro, and although they're a bit bulkier, they're more flexible so you can fold and squeeze them into a pocket. They also have a decently comfortable in-ear fit with angled earbuds that fit well within the contours of your ears. They're easy-to-use with a simple control scheme that's efficient and provides all the essential functions. Unfortunately, the slightly larger design makes them a bit unstable at times.
