– Weight: While both are relatively lightweight, the HD 600 is marginally lighter, which can be beneficial for long listening sessions.
Comfort and Ergonomics
Comfort is paramount for headphones, especially for audiophiles who spend hours immersed in their music. Both models come with plush velour ear pads, providing a comfortable fit, but there are some differences:
- HD 600: The ear pads are engineered to fit snugly, providing a nice balance of pressure without becoming uncomfortable over time.
- HD 650: The ear pads on the HD 650 are slightly thicker, creating a more enveloping feel, which can enhance passive noise isolation.
Technical Specifications
Understanding the technical details of the HD 600 and HD 650 is essential for making an informed decision.
Impedance and Sensitivity
Both headphones are designed for high-fidelity audio reproduction, but their specifications differ slightly.
- HD 600: Impedance of 300 ohms, sensitivity of 97 dB.
- HD 650: Impedance of 300 ohms, sensitivity of 103 dB.
The sensitivity in the HD 650 is slightly higher, which means it can produce louder sound at the same power level compared to the HD 600. This specification might make the HD 650 a better option for casual listening with mobile devices or lower-powered amplifiers.
Sound Quality: The Heart of the Matter
The most significant difference between the HD 600 and HD 650 lies in their sound signature and overall audio performance.
Sound Signature
-
Sennheiser HD 600: Often described as “neutral,” the HD 600 presents a balanced sound profile. It excels in clarity and precision, making it ideal for critical listening and professional monitoring. The highs are crisp without being harsh, while the mids are present and articulate. Bass is tight but not overpowering.
-
Sennheiser HD 650: The HD 650 is regarded as warm and smooth, with a slight emphasis on the lower frequencies. It provides a richer sound with a more pronounced bass response which can be characterized as more engaging for music genres such as jazz, blues, and electronic music. The highs are softer, preventing listener fatigue over extended sessions.
Soundstage and Imaging
Both headphones excel in terms of soundstage and imaging, crucial for an immersive listening experience.
-
HD 600: Provides an impressive soundstage, allowing listeners to perceive spatial cues effectively. Instruments feel well-placed within the mix, creating a realistic representation of live performances.
-
HD 650: While still offering a solid soundstage, the HD 650 leans towards a more intimate listening experience with slightly less width compared to the HD 600. However, it enhances the depth, offering great separation between instruments.
Frequency Response
Both models have similar frequency response ranges, but the frequency response characteristics differ.
| Frequency Range | HD 600 | HD 650 |
|---|---|---|
| Lowest Frequency | 12 Hz | 10 Hz |
| Highest Frequency | 39 kHz | 39.5 kHz |
- The bass extension on the HD 650 is slightly better, which contributes to its warmer sound profile.
Amplification Requirements
Both headphones have an impedance rating of 300 ohms, which means they require a quality amplifier to drive them effectively. Let’s examine how they respond to amplification.
Amplification for HD 600
The HD 600 can be driven by portable devices, but for the best experience, a dedicated headphone amplifier is recommended. Many users have found suitable pairing with mid-range to high-end amplifiers, unlocking the full potential of the headphones.
Amplification for HD 650
The HD 650 is generally considered a bit more forgiving with amplification. While they still benefit from a dedicated amplifier, they can produce satisfying sound quality even when paired with lower-powered devices. This makes them more versatile for users who may want to use them in varied settings.
Price and Value
Price is always a consideration when investing in high-end audio gear. Let’s explore the general pricing and which model may provide better value.
Typical Price Range
- Sennheiser HD 600: Typically found in the range of $300 to $400.
- Sennheiser HD 650: Generally priced slightly higher, in the range of $350 to $500.
Value Comparison:
While both models offer exceptional sound quality, the slightly higher price of the HD 650 can be justified by its richer sound profile and enhanced bass response. However, the HD 600 offers outstanding value for those seeking a more neutral sound signature.
Conclusion: Which One Should You Choose?
Ultimately, the choice between the Sennheiser HD 600 and HD 650 boils down to your personal preference and listening habits. Here’s a recap of the key differences and which might suit you best:
- Choose the HD 600 if you prefer a neutral sound signature that excels in clarity and precision, making it ideal for critical listening and professional use.
