We’ve all seen clever little flash drives and other gadgets made to look like cassette tapes. But this cassette-themed gadget is actually a speaker that blends the sentimental aesthetics of old technology with the sleek profiles of new gadgets. It’s rechargeable by USB, so there’s no need for bulky batteries.

The cassette hides an 800 milliwatt amp, making it just powerful enough to put it on your desk so you can listen to the music on your iPhone or other music player without headphones. It’s certainly not the most practical or powerful of speakers, but if you know someone who is stuck in the 70s or 80s it’s a fun bit of nostalgia for them.
