We needed to get some bikes up off the floor and this did the trick. Not really what I expected and will likely give it to a homeless person. Sound quality is good; no one reports any echos or anything while Im using it. I was skeptical but I like these better than regular qtips I thought there was hope. Me encantaron porque investigué mucho sobre audífonos y fueron la mejor opción en todos aspectos I think the value worth every penny. I normally would buy a large but bought an XL. We bought this to help us get our luggage and holiday gifts home. The E-mount adapter is built in.
