Imaging your Imagination
The HD 650s signature sound starts with Sennheiser's in-house acoustics. Audio pros know that the best components perform at their peak when nothing stands in their way. Its no surprise that the response and dimensional soundstage of the HD 650 are smoothits open earcups provide each and every soundwave ample room to expand as they would in nature. The 42mm transducer deploys a 38mm diaphragm with aluminum voice coil specifically tuned for extended, critical listening: overall treble and low-frequency presence are effortless while midrange is reproduced with lifelike composurenone sacrificing their organic roots to get there. Modern high-resolution sample rates benefit especially well from the HD 650s willingness to reveal subtle nuances without resorting to over-hyping the treble range.
Each transducer manufactured is measured against rigid specifications and paired with a perfect match for consistent representation of the entire frequency spectrum in both channels. By reducing variances between left and right channels, the headphone reproduces mastering-grade sound independent of room acoustics or loudspeaker positioning..

Made in Ireland at a state-of-the-art production facility, the HD 650 combines the best of modern transducer manufacturing with the attention to detail required to handle a wide variety of acoustic materials. Sennheiser's production tolerances are extremely tight, ensuring that your HD 650 experience is consistent with those all over the globe, whenever or wherever it was purchased. For example, the resonators feature stainless steel mesh to guarantee uniform performance after manufacturing. Even better, most parts on the HD 650 are modular, making it a dream to keep operational as your go-to reference monitoring solution. From the velour pads to the earcup grille pattern, each component was crafted to guarantee a next-level personal sound experience so you can enjoy your music even more.
