If you miss the days of mixtapes on actual tapes, then the NVDRS Cassette Tape mp3 player will let you relive Hip-Hop’s golden age without pulling a Radio Raheem.

The NVDRS is designed to replicate the classic cassette tape in more ways than one. Coming in 45/60/90 minute formats, just like the cassette, the three NVRDS models will be able to hold 10/15/20 songs respectively. And just like a tape player, you’ll have to physically rotate the spools to fast forward, rewind and skip through tracks.

Forget a pocket full of extra double-A batteries, the craziest feature of the proposed player would be the manual charging. Similar to the track controls, users will have to rotate one of the spools to charge the battery via kinetic energy making the NVDRS, self sustainable and eco-friendly.
