excellent value however a design flaw is that the headphones do not have an auto-off function especially when it's foldable

Pretty good purchase for the price! comfortable to wear and reasonable sound quality and tonal spectrum, Just need to pair with my MacBook again via the bluetooth settings but having the aux outlet is a huge relief and bonus
