Our take on the brand
Product Strengths
- Top-notch build quality, with premium materials and a comfortable design
- Excellent sound quality with a balanced presentation—no outstanding weaknesses across the frequency spectrum
- Two sets of earpads are included (Duo and Alcantara) for sound customization
- The design has a strong aesthetic, and the magnetic pad swapping system is easy to use
- Wider soundstage and more three-dimensional imaging
Product Considerations
- Sensitivity has dropped compared to the original Empyrean and Elites, requiring slightly more power to drive
- There might be a little bit of extra emphasis around the three to four kilohertz mark, which can make them a little bit fatiguing—a little bit bitey in the treble
- Not the largest soundstage that can be experienced at this price point
- The open design leaks sound and doesn't offer much in the way of isolation
- Those particularly sensitive might hear some spikiness in the lower treble region
Comparisons (according to reviewers)
- Vs Original Meze Empyrean: Empyrean II has a more neutral tuning, is more defined, and has better detail separation
- Vs Meze Elite: Empyrean II offers stronger bass extension and more of the engaging emotional delivery
- Vs Meze Elite: The Elite seems more expansive than Empyrean 2, though not by a lot
- Vs HIFIMAN HE1000SE: The HE1000SE sound is more spacious, the bass is snappier, and the amount of detail is slightly above the Elite and Empyrean
Takeaway: The Empyrean II is an enjoyable headphone, improving on the original with a more accurate and versatile sound that maintains the core Empyrean identity. The comfort, build quality, and well-balanced sound make it a great choice for a high-end listening experience.
