What reviewers said
Grado Signature S750
The Grado Signature S750 is an open-back, wired over-ear headphone that blends a classic, airy presentation with modern technical detail. Its 50mm dynamic driver delivers a wide, spacious soundstage with strong clarity, though its bright tuning and premium price point may not suit everyone. Build quality is solid and the detachable cable is a practical touch, but comfort and fit remain subjective considerations.

- Pro:Strong technical detail and clarity
- Pro:Solid build quality with detachable cable
- Con:Bright tuning may be fatiguing for some
- Con:Comfort and fit can be divisive

ZMF Tessidera
The Tessidera is a premium open-back planar headphone that channels ZMF's signature warm, musical tuning into a planar driver format. It delivers a smooth, full-bodied sound with particularly rich vocals and natural timbre, all while being relatively easy to drive for a high-end model. The build is solid overall, though the stock grill finish shows minor cosmetic imperfections.

- Pro:Excellent timbre and natural instrument reproduction
- Pro:Relatively easy to drive despite large 80mm drivers
- Con:Mid-forward balance can vary with amplifier pairing
- Con:Minor cosmetic roughness on the stock grill
