Our Thoughts RADAR AI

This is a buyer’s market for portable Bluetooth speakers, and the €89 asking price for the used Harman Kardon ONYX is a strong deal, sitting just above the 25th percentile of €86 and well below the median of €120 from 26 recent EUR listings. It’s not a bargain below the 25th, but it’s clearly excellent value in today’s market, especially compared to the 75th percentile at €136.

The ONYX is well-regarded for its warm, room-filling sound and sleek, compact design that balances style with performance. It handles vocals and bass with surprising depth, making it a favorite for casual listening and small spaces. At this price, you’re getting a reliable, well-loved speaker with meaningful upside—likely original-owner condition and no hidden wear if the listing is clean. Unless there’s a specific caveat like missing power cable or age-related battery drift (more common in older Bluetooth models), this is a buying opportunity, not a risk.

Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.

About Harman Kardon

Harman Kardon traces its origins to 1953, when Dr. Sidney Harman and Bernard Kardon, both engineers frustrated with conservative audio manufacturing at the David Bogen Company, invested $5,000 each to launch their venture in Westbury, New York. Their debut product, the Festival D1000, became the world's first compact AM/FM hi-fi receiver, blending breakthrough technology with sleek design to make high-fidelity sound accessible beyond technical enthusiasts. Pioneering innovations like the 1958 Festival TA230 stereo receiver, the 1959 Citation II ultra-wide bandwidth tube amplifier, and the 1970 CAD5 hi-fi cassette recorder with Dolby noise reduction cemented their legacy in simplifying premium audio for the home.

The brand focuses on integrated receivers, amplifiers, tuners, and speakers that emphasize performance, reliability, and elegant industrial design. Over decades, it expanded into home theater systems and automotive audio, powering systems in vehicles from Land Rover and BMW to Volvo and Polestar. While not delving into turntables, DACs, headphones, or cables, Harman Kardon prioritizes cohesive hi-fi components that deliver warm, detailed sound without unnecessary complexity.

Harman Kardon holds a solid mid-tier position in the hi-fi market, renowned among knowledgeable buyers for its enduring quality and value rather than ultra-high-end exotica or vintage collector status. Now part of Harman International, it appeals to discerning listeners seeking dependable, stylish gear that echoes its innovative heritage without commanding boutique premiums.
