These are perfect for keeping the headphones in the very best condition. I figured that was on me and bought a replacement (another $150). The medium size fits me well! These are super lightweight just as any Crocs shoe. El adaptador no es Samsung. Im glad to say that this device does excel in this department and it really doesnt have many competitors. Also, Ive only had these for maybe a couple weeks and Ive only used them a few times and been gentle with them. The plate is powder-coated, and the Ubolt is stainless steel, the nuts and washers are prone to rust however so I put them on my hitch and painted them as no one likes rusty nuts. Great Buy! Very sleek and takes very less space in the bagCons:1) only Con that i can point out is the battery life.
