Te koop aangeboden: een harman/kardon onyx studio 4 bluetooth speaker in goede staat. De speaker werkt perfect en levert een uitstekende geluidskwaliteit. Ideaal voor thuisgebruik of onderweg. Wordt g
€60 sits just above the median of €58 and well inside the normal used range between €39 and €69, so this is a fair buy rather than a bargain or an ambitious ask. It is not priced low enough to call it a steal, but it is close enough to market that a clean unit can be worth moving on.
That makes sense for a well-liked portable speaker: the Onyx Studio 4 is valued for its punchy, room-filling sound and easy Bluetooth use, and included cables/accessories add practical value if they’re complete. At this price, the main buyer check is simple: confirm battery health, charge stability, and that both the speaker and its accessories are present and working cleanly.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
