The Samsung U Flex are decent wireless in-ears for most use cases. They sound decently well-balanced if a bit sharp on some tracks, and have an around-the-neck design that's a bit bulkier than most but flexible enough to fit into some pockets. They have a decent battery life and an excellent wireless range but struggle to isolate in loud, noisy environments. They're also fairly limited in customization options if they're not paired with a Samsung device which is a bit disappointing.

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. The neckband would pull on the earbuds causing them to slip out of your ears, once in while, when doing more demanding physical activities like jumping jacks.
