Comparing the beyerdynamic DT 900 PRO X vs Sennheiser HD 660S2: A Detailed Audio Showdown
When it comes to high-fidelity headphones crafted for audiophiles and professionals alike, the beyerdynamic DT 900 PRO X and the Sennheiser HD 660S2 stand out as two compelling contenders. Both are wired open-back headphones designed to deliver transparent and precise sound reproduction. Each offers detachable cables and robust build quality featuring recyclable materials and reinforced joints, emphasizing durability and environmental consciousness. Despite their similarities in connectivity and design philosophy, they diverge notably in audio performance parameters, impedance, and included accessories, making them tailored for varied listening contexts and preferences.
Exploring their core functions, both models forego active noise cancellation and smart features, focusing purely on wired audiophile-grade audio. The DT 900 PRO X, released in 2021 from Germany, boasts a maximum input power of 100 mW and a relatively low impedance of 48 Ω, making it easy to drive from a variety of audio sources. On the other hand, the HD 660S2, crafted in Ireland with a 2023 release, pushes audiophile boundaries with a much higher maximum input power of 500 mW and impedance of 300 Ω, catering to users with dedicated headphone amplifiers seeking pristine audio fidelity.
Distinctive Attributes of the beyerdynamic DT 900 PRO X
The DT 900 PRO X shines in its user-friendly design tailored for versatility. Its 48 Ω impedance allows for easy compatibility with a wide range of devices, including portable players and standard headphone outputs, without the need for amplification. Weighing in at 0.76 kg, it offers a firm but comfortable clamp force of 1.1 N that ensures a secure fit. The headphone's smaller ear cup inner diameter of 2.56 inches may provide a more intimate seal for some users seeking focused sound isolation.
Utilizing a Mini XLR connector, the DT 900 PRO X ensures reliable cable connection and easy replacement if needed. Included with the package is a soft protective pouch and a 3.5mm detachable audio cable, enhancing portability and convenience for on-the-go use. Although it lacks features like app customization or active noise cancellation, its focus remains firm on delivering detailed sound with an impressive total harmonic distortion of 0.2%, respectable for its class. Its frequency response up to 40,000 Hz covers the essentials of an audiophile listening spectrum.
The Strengths of the Sennheiser HD 660S2
On the other side, the Sennheiser HD 660S2 elevates audio reproduction with a remarkably low 0.04% total harmonic distortion, signifying cleaner sound with minimal coloration. With an impressively high 300 Ω impedance, it's tailored for use with dedicated headphone amplifiers, rewarding audiophiles who prioritize sonic accuracy. Its sensitivity of 104 dB and extended frequency range up to 41,500 Hz allow for excellent dynamic range and detailed high-end extension.
The HD 660S2 also distinguishes itself through its physical construction ; lighter at 0.57 kg with a wider ear cup inner diameter of 2.76 inches, which some users may find more comfortable for extended listening sessions. It incorporates a proprietary detachable cable connector paired with a robust hard carrying case, offering excellent protection during transport. The cable terminates in a 6.3mm plug, reflective of its professional-grade focus. While it doesn't provide app support or customizable EQ, the headphone's pristine sound quality compensates for these omitted extras.
Quick Take
The beyerdynamic DT 900 PRO X offers an accessible, durable, and versatile listening solution perfect for users looking for solid performance without needing extra amplification. Meanwhile, the Sennheiser HD 660S2 caters to discerning audiophiles demanding superb fidelity and are equipped with proper amplification setups. Its exceptional sound purity and build quality make it ideal for critical listening environments.
Bottom Line
Ultimately, if your priority is audiophile-grade sound with low distortion and you have dedicated gear to power high-impedance headphones, the Sennheiser HD 660S2 is the better investment despite its higher price. However, for those seeking excellent sound quality with ease of use, portability, and a more affordable price tag; like the $319.99 at beyerdynamic Official Store; the beyerdynamic DT 900 PRO X proves to be a highly capable competitor.
Verdict
Winner: Sennheiser HD 660S2 ; Delivers superior sound fidelity, lower distortion, and professional-grade tuning ideal for audiophiles with dedicated amplification equipment.
Runner-up: beyerdynamic DT 900 PRO X ; A more affordable, easier-to-drive headphone with solid build quality and versatility that suits everyday listening needs.
