Taking a walk with your music was all the rage in the 80's. All you needed was your favorite cassette, headphones, and a portable tape player, possibly a pencil (IYKYK). Today, all you need is Crosley's Mini Cassette Player Bluetooth Speaker. This compact speaker looks just like a retro cassette player with the convenience of digital streaming. Sync two of them together and you can listen in stereo. Rechargeable and ready to travel, music on the run has never been cooler.
