Go back to the ’80s with this retro-style speaker that looks like an old-school Walkman. Instead of popping a cassette in, stash your smartphone inside of it, then clip it onto your belt loop for full effect. It has working control buttons and a 3.5mm aux in jack. Why not go all-in and use it with that Bluetooth cassette player?
It’s been 40 years since the Sony Walkman first came on the scene, and since been supplanted by CDs, MP3s, and streaming. But if you’re craving that old cassette tape sound, NINM Lab’s portable player/recorder has Bluetooth 5.0, so you can wirelessly send its sounds to a speaker or headphones. Sadly it’s not stereo.
