What is this thing? https://vancouver.craigslist.org/rds/msg/d/surrey-rare-ibanez-rock-play-cassette/7726295905.html
I think there were similar models from other brands, I've posted them before, I just can't remember where, maybe in the for sale mega thread? Without seeing more photos, I think there's a 1/4" jack to plug your guitar into, you can listen through your headphones or record your work without waking everyone up. They don't look professional so don't spend too much money on one.
Here's some more information about these unusual players. I'm not about to buy one. https://reverb.com/item/14867442-ibanez-rock-n-play-walkman-early-1990s "Here’s your chance to own a little obscure piece of musical history;The Rock’n’Play was a cross between a Sony Walkman and a Scholz Rockman, it was a device you could plug your electric guitar into and hear it through headphones along with the cassette tape you wanted to jam along with. The is distortion and chorus effect for the guitar, and a pitch control and half speed switch (which keeps the music in tune but drops it an octave) for the tape. It’s fully functional."
