Beats Flex is a good pair of headphones and a decent choice if you’re picking up an iPhone 12 and don’t want to spend more on AirPods. The smarts that come from the W1 chip is great to have at this price and the sound quality is ok, if a bit flat.
Some AirPod smarts for a lot less; Neckband design can be useful; USB-C is great for Android users; They're cheap
Sound quality is a little bit flat; USB-C annoying for iPhone users; No sweat resistance makes them harder to recommend for the gym
