Sennheiser HD 660S2 700240
Why we recommend this ▼
The 300-ohm ultra-light aluminum voice coil delivers an intimate, natural timbre with notably enhanced sub-bass extension compared to its predecessor. The open-back design provides a relaxed, high-fidelity soundstage with excellent impulse response, though the high impedance demands a dedicated amplifier. These headphones are best for critical listeners and mixing engineers who prioritize natural tonality and bass texture over portable convenience.
