Excellent build

Foldable headphones that looks great and pretty comfortable to use for the best experience. In terms of sound quality, it's clear with crisp and decent enhanced bass volume that you can hear and differentiate. Soft earmuffs for great experience and the most amazing feature that it has is that beside of it being bluetooth compatible able to connect to your various devices, you can also use it by inserting a micro SD card in the slot and play your music on it or, if you want to go semi old school, through the standard 3.5mm auxiliary cable that you can insert in the slot. Product comes nicely included with one 3.5mm auxiliary cable in case you do not have one. You don't have to turn the headphones on in order to use the wired function which is nice, saving you that battery for later use if say you're on a road trip or something.
