Against your comp set, US$28 sits just under the US$30 median and inside the US$27–US$33 interquartile band, so this reads as a fair-to-lightly-positive buy rather than a steal. It is not below the 25th percentile, but it is priced a touch better than the middle of the market, which is a respectable spot for a used cable/accessory item.
What makes it interesting is that Optimus small parts and accessories can be annoyingly hard to source cleanly, so a complete, presentable example has practical value if you need the piece to finish a setup. With condition shown as unknown, the main thing to verify is completeness and whether there’s any corrosion, cracked insulation, or bent hardware; at US$28, I’d still view it as a sensible grab if the photos look honest and the item is actually intact.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Optimus is best known as a RadioShack private-label audio brand rather than an independent hi-fi manufacturer. The name traces back to RadioShack’s in-house branding, with “Optimus” used on some products from the late 1960s and more broadly on audio gear in the 1980s and 1990s. It does not have a clearly identifiable standalone founder in the way a dedicated hi-fi brand would; its heritage is tied to the RadioShack retail chain in the United States.
The line covered a broad range of consumer electronics, including stereo receivers, amplifiers, speakers, cassette decks, turntables, and later some home-theater and portable audio products. Depending on the era, many Optimus components were sourced from overseas OEM manufacturers, especially in Asia, and sold through RadioShack’s stores as house-brand alternatives to mainstream consumer audio lines.
In the market, Optimus sits firmly in the mass-market and mid-fi category rather than the high-end segment. Today it is mostly remembered by vintage-audio collectors and RadioShack enthusiasts, with certain receivers and speakers drawing interest for their retro appeal and occasional value. It is not generally regarded as a boutique or audiophile-first brand, but some models remain noteworthy for solid build and nostalgic charm.
