It carries forward the smooth and effortless sound found in the open-back 600 family with a modern, airy signature that balances honesty with deep and articulate bass. Thanks to a high damping factor, the 150-ohm aluminium voice coil excels at speedy transients and well-defined instrument tails for punchy dynamics across the entire frequency spectrum—a boon for audiophiles and passionate gamers trying to consume as much detail as possible in a given moment.\u003c\/p\u003e\n\u003cp\u003eSituated in an iconic chassis beloved by audiophiles, gamers and streamers alike 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, modelling the behaviour of open-back transducers while recreating the triangular imaging of a great loudspeaker setup in an expertly tuned room. This immersive presentation drops the listener into the centre of the action with impressive cue location, whether it is a rare live concert recording or massive online multiplayer showdown.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Sennheiser HD 620S Closed-Back Audiophile Headphones Profile\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/HD_620S_Mood_Shot_PKF9589_16x9_20_1.png?v=1715003809\" style=\"margin-bottom: 16px;\"\u003e\u003c\/p\u003e\n\u003ch2\u003eCase closed\u003c\/h2\u003e\n\u003cp\u003e​Open headphones are an audio purists’ favourite, however closed headphones are invaluable for listening when isolation from the world around the listener is essential. Audiophiles are accustomed to trading the natural response and wide imaging of open headphones in order to keep distractions at bay, or from disturbing roommates, spouses and co-workers. No doubt, the ​ HD 620S is a breakthrough in real-world performance, offering the dramatic soundstage they want absent the fatiguing, boxy sound associated with sealed cans.\u003c\/p\u003e\n\u003cp\u003e\u003cimg alt=\"Sennheiser HD 620S Closed-Back Audiophile Headphones Driver Technology\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Senn_HD_620S_Exploded_View.png?v=1715003826\" style=\"margin-bottom: 16px;\"\u003e\u003c\/p\u003e\n\u003ch2\u003eYou have new connections\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003e​\u003c\/strong\u003eThe HD 620S was built to last with a metal-reinforced headband and earcup housings. An included storage pouch keeps dust at bay with ample space for the detachable cable too, for tidy keeping. The 1.8 meter \/ 6 foot cable terminates to a single-ended 3.5mm stereo plug with an integrated locking screw for the included 6.3mm adapter. Available this summer, an optional balanced 4.4mm cable will let audiophiles tap into a growing range of hi-fi devices supporting the popular connector. The HD 620S shares the twist-and-lock single-sided cable design with other Sennheiser headphones, giving the user plenty of aftermarket options including different lengths and an in-line microphone.\u003c\/p\u003e\n\u003ch2\u003eIN THE BOX\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eHD620S \u003c\/li\u003e\n\u003cli\u003e1.8m Cable with 3.5mm (1\/8\") termination\u003c\/li\u003e\n\u003cli\u003e3.5mm (1\/8\") to 6.35mm (1\/4\") adapter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSPECIFICATIONS\u003c\/h2\u003e\n\u003ctable border=\"1\" style=\"width: 99.9987%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eWearing style\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003eWired headband\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eEar coupling\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003eOver-ear (Circumaural)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eEar pad material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003eArtificial leather\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eAcoustic principle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003eClosed-back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eTransducer principle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003eDynamic (single driver)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eTransducer size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003e42 mm with a 38 mm diaphragm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003e6 Hz - 30,000 Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003e150 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eSound Pressure Level (SPL)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003e105 dB (1 kHz \/ 1 Vrms)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eTotal Harmonic Distortion (THD)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003e\u0026lt;0.05% (1 kHz \/ 90 dB SPL)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 48.204%;\"\u003e\u003cstrong\u003eMagnetic field strength\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 49.2407%;\"\u003e6.25mT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":47198823842025,"sku":"700401","price":399.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0065\/4432\/6771\/files\/Sennheiser_HD_620S_Over-Ear_Noise_Cancelling_Headphones_for_Superior_Sound.png?v=1762466891","url":"https:\/\/audio46.mom\/products\/sennheiser-hd-620s","provider":"Audio46 Headphone Store","version":"1.0","type":"link"}
