Review subject to updating upon break-in, but may be headed for a return, as they seem very robust with not a lot of give for this particular pair. I didn?t expect much from these headphones, because I usually pay the extra for higher quality, name brand speakers. They arrived on time and in perfect condition. Between slippery inside and the fastener not fastening very tightly the slip around on my foot. We used it as a hat rack. Out of the box they would not turn on or charging didn?t allow me to turn them on. I like it feels good . So, bose is not very versatile, like you cant watch movies or watch FB videos. They both lasted me 5+ years each. Es muy práctico, del tamaño correcto para mi y muy fácil de armar
