Sennheiser HD620s Closed Back Headphone

Sennheiser HD620s Closed Back Headphone. At the heart of the HD 620S is a custom-tuned 42mm dynamic transducer made at Sennheiser's s state-of-the-art Tullamore, Ireland transducer plant.

It carries forward the smooth and effortless sound found in the open-back 600 family with a modern, airy signature that balances midrange with deep and accurate bass.

Thanks to a high damping factor, the 150-ohm aluminum voice coil excels at speedy transients and instrument details for punchy dynamics across the entire frequency spectrum — perfect for audiophiles and gamers trying to consume as much detail as possible in a given moment.

Using an iconic chassis beloved by listeners for its long-term wearing comfort, the HD 620S elicits a sense of confidence while providing an instant sweet spot. Metal appointments not only feel great to the touch but serve an acoustic purpose as well–the steel plate closing off the back volume is an efficient isolator that manages the internal reflections that cloud the purity of an acoustic signal within.

The angled baffle is remarkably open to encourage the free movement of air, modeling the imaging of a great loudspeaker setup. This immersive presentation drops the listener into the center of the action with impressive cue location.

Audiophiles are accustomed to trading the natural response and wide imaging of open headphones in order to keep distractions at bay, or from disturbing others. HD 620S is a breakthrough in real-world performance, offering the dramatic soundstage they want absent the fatiguing, boxy sound sometimes associated with sealed cans.

Sennheiser HD 620S is built to last with a metal-reinforced headband and earcup housings. An included storage pouch helps for travel. 

The 1.8m cable has a 3.5mm plug with an locking screw for the included 6.3mm adapter. The HD 620S shares the 2.5mm twist-and-lock single-sided cable design with other Sennheiser headphones.
