When choosing high-quality headphones, noise isolation is a critical factor for many audiophiles and casual listeners alike. The Hifiman Sundara and Oppo PM-3 are two popular models that often come up in discussions about premium headphones. This article compares their noise isolation capabilities to help you decide which might be better suited for your needs.
Overview of the Hifiman Sundara
The Hifiman Sundara is a planar magnetic headphone known for its detailed sound and open-back design. It features a lightweight construction and a wide soundstage, making it ideal for home listening. However, its open-back design inherently limits noise isolation, allowing ambient sounds to enter.
Overview of the Oppo PM-3
The Oppo PM-3 is a closed-back, portable headphone designed with noise isolation in mind. Its sealed ear cups help block out external noise, making it suitable for commuting, travel, or noisy environments. Its design emphasizes portability and effective noise reduction.
Noise Isolation Comparison
The primary difference between these two models lies in their design and resulting noise isolation. The Sundara’s open-back design offers superior sound quality and a natural listening experience but provides minimal noise isolation. Conversely, the Oppo PM-3’s closed-back design excels at blocking external sounds, offering significantly better noise isolation.
Open-back vs Closed-back Design
Open-back headphones like the Sundara allow air and sound to pass through the ear cups, leading to a more natural and spacious sound. However, this openness also means external noises easily enter the ear cups. Closed-back headphones like the Oppo PM-3 prevent sound from escaping and external noise from entering, enhancing noise isolation.
Practical Implications
- Sundara: Better for indoor use, audiophile listening, and environments where external noise is minimal.
- Oppo PM-3: Better for commuting, travel, and noisy environments where noise isolation is essential.
Conclusion
If noise isolation is your top priority, the Oppo PM-3 clearly outperforms the Hifiman Sundara due to its closed-back design. However, if you value sound quality and an open, spacious soundstage, the Sundara might be more suitable, with the understanding that external noise will be more audible.
