Would 100% recommend! El envío muy rápido y llego en perfectas condiciones. Passons au positif! These are an update to the Sony Wi-C300 Bluetooth headphones that they introduced a little over a year ago. I like the mute button too! forward. Manufactures care guidelines didnt work (damp wipe) and you cant toss this wonderful - and expensive! I only usually wear them a couple hours at a time and the battery life is fine for that. It took me a while to get it off with hot water. Instead of breaking the chain to thread it, i just popped one screw off the cage.
