A Detailed Comparison: Sennheiser HD 660S2 Vs. beyerdynamic DT 1990 PRO MKII
When it comes to high-end, wired, open-back headphones for audiophiles and studio professionals, both the Sennheiser HD 660S2 and beyerdynamic DT 1990 PRO MKII stand out. Both headphones offer a wired connection with detachable cables and robust build quality enhanced by reinforced joints, recyclable materials, and a hard carrying case for transport. Neither includes wireless features, voice assistant support, nor ANC capabilities, focusing instead on pure, uncompromised audio quality. However, their key differences; ranging from audio impedance and sensitivity to dimensions and usability features; cater to distinct preferences and listening setups. This review will break down their critical specs and help identify which model meets your specific needs.
The Lightweight Audiophile Powerhouse: Sennheiser HD 660S2
The Sennheiser HD 660S2 excels as an audiophile-grade headphone engineered for users with high-end desktop amplifiers. With an impressive 300 Ω impedance, it demands more power but rewards with exquisite detail and rich sound texture. Its maximum input power of 500 mW provides headroom for loud, distortion-free listening. While it has a slightly lower sensitivity rating of 104 dB SPL compared to its competitor, the HD 660S2's tonal balance is finely tuned for critical monitoring and extended listening sessions.
In terms of comfort, the HD 660S2 features larger ear cups, with an outer diameter of 4.33 inches and an inner diameter of 2.76 inches, comfortably accommodating larger ears. Weighing just 0.57 kg, it is noticeably lighter, reducing fatigue during prolonged use. Its slightly firmer clamp force (1.1) ensures a secure fit, which is essential for stable sound delivery without excessive pressure.
Connectivity-wise, the HD 660S2 utilizes a proprietary detachable cable connector and connects with a standard 6.3mm plug. While it does not feature a protective pouch, it comes with a hard carrying case to safeguard the headphones. This setup, combined with its recyclable materials and reinforced joints, underscores a blend of quality and environmental mindfulness.
Distinctive Traits of The beyerdynamic DT 1990 PRO MKII
The beyerdynamic DT 1990 PRO MKII offers an alternative that emphasizes versatility and user convenience. With a considerably lower impedance of 30 Ω and a higher sensitivity of 114 dB SPL, these headphones are easier to drive from portable devices or less powerful amplifiers, making them more adaptable for casual listeners and professionals alike.
One notable specification advantage is the slightly better total harmonic distortion (0.03%), suggesting marginally cleaner output under certain conditions. The DT 1990 PRO MKII also has a high-frequency response extending up to 40,000 Hz, very close to the Sennheiser's 41,500 Hz limit. Its connection comes via a Mini XLR detachable cable, also 6.3mm plug compatible, favored by many professionals for secure attachment.
Quick Take
The Sennheiser HD 660S2 impresses with its lightweight comfort, larger ear cups, and dedication to audiophile-grade sound utilizing its high 300 Ω impedance, making it ideal for users with powerful amplifiers. Conversely, the beyerdynamic DT 1990 PRO MKII shines in adaptability, offering easier device compatibility with 30 Ω impedance, foldable swivel ear cups, and an included protective pouch to enhance portability and resilience.
Bottom Line Recommendation
Choosing between these two flagship headphones boils down to how you value portability versus premium desktop listening. The Sennheiser HD 660S2 is a compelling choice if you prioritize lighter weight, larger ear cups, and plan to pair with a high-end amplifier for crystal-clear detail. On the other hand, the beyerdynamic DT 1990 PRO MKII is best suited for users looking for enhanced versatility with portable-friendly impedance, clever swivel design, and extra carrying accessories, albeit at a higher price tag.
Winner: Sennheiser HD 660S2 - Offers superior comfort with larger ear cups, lighter weight, and is perfect for audiophiles using dedicated high-impedance amplifiers, all at a more accessible price point.
Runner-up: beyerdynamic DT 1990 PRO MKII - Best for those needing lower impedance for easy driving, foldable swivel cups for convenience, and added portability features, though it comes with a higher price and heavier build.
