# Harman Kardon Onyx Studio 4 – Buyer Notes
Price Assessment
At EUR 40, this is a solid entry point for the Onyx Studio 4. Your comparable database puts the median used asking price at EUR 90, with the 25th percentile at EUR 37—so this listing sits right at the lower edge of the range, suggesting either motivated selling or potential condition issues worth investigating. The Onyx Studio 4 is now several generations old (launched around 2014), and while it remains a desirable compact Bluetooth speaker, the newer Onyx Studio 5 and 6 have displaced it in the secondary market. That age works in your favor price-wise, but don't assume bargain-basement pricing means pristine condition.
What to Verify
Before committing, confirm the battery holds a full charge and doesn't drain rapidly—age is the enemy of lithium cells in these units. Check that both drivers produce clean output across the frequency range (no distortion, crackling, or dead zones), and verify all touch controls respond consistently. The listing says "unknown condition," which is a red flag; push the seller for specifics on cosmetic wear, any cracks in the leather, and whether the charging cable and original accessories are included. A missing or degraded cable adds real friction to the deal at this price.
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.
