Introduction

This page demonstrates the label and provenance expected when an earlier sister-site review is adapted.

Design and build

Serviceable pads and headband parts improve long-term ownership, but total weight remains the dominant ergonomic concern.

Measurements

Frequency response · Prototype fixture · positional average
Prototype demonstration data — not a real product measurement.

Listening impressions

The fictional notes prioritise tonal consistency and comfort across long sessions rather than prestige materials.

Conclusion

The Reference 2 is recommendable only after confirming fit, a limitation the verdict makes impossible to miss.
