Your dad likely has fond memories of the Golden Age of radio. He may not understand a lot of the new technology, but radio he groks radio. And perhaps other than his boyhood Philco or Zenith, he'll never see a radio as beautiful until you give him a Tivoli Audio table radio – now with Bluetooth.
Radio Silenz headphones also come in these black ash and have one other cool feature – the "defeat" button fades down the outside noise so you can hear announcements or clerk questions or anything sound not coming through the headphones without taking the headphones off. An airline adapter is included.
