Like their older brothers the BNX-60 - middling at best, yet somehow What Hi-Fi? 5-Star rated - the low price seemingly forgives all ills and leads to a skewed score. @JayCee is right; these are a 5/10 product all day long.
These seem like rebranded Kitsound Immerse headphones with regards to features. If the price of the Lindy is a bit much you can pick up the Immerse headphones for less than half the price. For the money they are not bad and are pretty much the same if you are looking for a pair of bluetooth headphones with ANC.
