We Are Rewind - [CURTIS] Portable Cassette Player with Bluetooth - Black

The GB-001 brings the boombox into a whole new era. Inspired by the iconic ‘80s design, this neo-retro gem is packed with cutting-edge technology. Following the success of the WE-001 cassette player, it arrives just in time — with cassette sales skyrocketing by over 400% in the past decade — to bring analog sound roaring back.

With 104 watts of power delivered through four Hi-Fi speakers (two woofers for deep bass, two tweeters for crisp highs), the GB-001 turns any space into a full-on concert hall. It plays and records both Type I and Type II cassettes with a premium-grade mechanism, and an adjustable motor for ultra-stable playback.

But this boombox is more than a retro revival — it’s fully modern: Bluetooth 5.4, a rechargeable and replaceable battery, microphone input, fine-tuned sound controls (bass, treble, balance), backlit VU meters, and even an amp function for your guitar. Ready for a rap battle or a karaoke night? Plug in two wireless mics and put on a show.
