Listed as tested, this is a strong bargain at USD 25: it sits well below the comparable-listing 25th percentile of USD 63, versus a USD 115 median and USD 229 75th percentile. Even allowing for the age and proprietary nature of the system, the price leaves plenty of room for a worthwhile pickup.
The appeal is the included S-AIR amplifier, matching speakers, and transceiver card: the TA-SA100WR can deliver a respectable 80 watts per channel into 3-ohm loads and was designed for wireless surround use. The card is particularly important, since these amplifiers depend on compatible Sony S-AIR equipment and pairing hardware; having it included materially improves the package. Confirm that “tested” means clean wireless operation, both channels, and no speaker damage, but at USD 25 this is an easy buy for a compatible Sony home-theater project.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Sony emerged from the ruins of post-World War II Japan, founded on May 7, 1946, by Masaru Ibuka and Akio Morita as Tokyo Tsushin Kogyo K.K. in Tokyo's Nihonbashi district. Starting with radio repairs and Japan's first magnetic tape recorder, the duo secured transistor licensing from Bell Labs, pioneering the TR-55 transistor radio in 1955. Renamed Sony Corporation in 1958—from the Latin "sonus" for sound—the brand symbolized Japan's ascent from cheap imitations to innovative leadership, fueled by Ibuka's engineering prowess and Morita's global marketing vision.
Sony's hi-fi legacy spans headphones, amplifiers, speakers, turntables, and DACs, alongside landmark formats like the Compact Disc in 1982 and Blu-ray. Iconic products include the Walkman for portable audio revolution and Trinitron televisions, blending consumer accessibility with cutting-edge tech. Today, offerings like the Signature Series headphones and ES amplifiers target discerning listeners seeking refined soundstaging and dynamic range.
Positioned as a mid-to-high-end powerhouse, Sony commands respect among knowledgeable buyers for blending mass-market reliability with premium performance, outpacing many pure audiophile brands in innovation and value. Far from vintage relic or niche boutique, it dominates with forward-thinking engineering, holding strong market share in headphones and streaming ecosystems.
