Vintage Prosonic Go Stereo Portable Cassette Player (New Old Stock)

This is a vintage Prosonic Go Stereo portable cassette player, appearing in its original 'New Old Stock' (NOS) blister pack. The player itself is constructed from matte black plastic with rounded corners, featuring simple mechanical controls including play, rewind, fast-forward, and stop buttons typical of late 1980s to early 1990s consumer electronics. The branding 'Prosonic' is prominently displayed in a teal-toned font. The item is accompanied by a set of lightweight over-ear headphones made of a thin metal headband and black foam earpads. The packaging features a tan cardboard backing with a retro rainbow stripe design (red, orange, yellow, and blue) and bold white 'GO STEREO' typography. The plastic blister wrap remains sealed, which is a significant value factor. While the packaging shows minor corner wear and slight yellowing consistent with age, the item inside appears pristine and unused. The compact size and lightweight materials are indicative of the era's budget-friendly portable audio market, designed for on-the-go listening similar to the Sony Walkman brand. The craftsmanship is utilitarian, utilizing mass-production molding techniques from the late 20th century.
