Enjoy your music on a completely new level.
How do you one-up a line of legends?
High-end Sennheiser headphones like the HD 600, HD 650, and HD 660S are known for their balanced, natural sound. The HD 660S2 shares this legacy with a revised 300-ohm coil for cleaner impulse response, a compliant surround for lower resonant frequency, and optimized airflow for better sensitivity.
They feel as great as they sound
The velour earpads can only be described as a tactile pleasure. With the right amount of tension for proper acoustic positioning and supple padding, the headband won’t draw attention away from your music, either. As an open-back design, the HD 660S2 gives your ears an extremely comfortable climate.
Natural, non-fatiguing sound for gamers and streamers.
Do you recognize the feeling of listening to harsh sounds that annoy you for long periods of time? The HD 660S2 has been developed for detailed yet fatigue-free treble reproduction to keep you focused all day long. With comfort this good, you’ll be ready to extend your gaming sessions even further.
