They’re all aiming for readability, however very like digital camera makers, every high-end headphone model places its personal taste on the expertise. Followers love Sennheiser’s HD 600 collection not just for their exceptional definition and dynamics, but in addition for the delicate method by which they specific these revelations. In contrast to some headphones that may sound extra “scientific” or sharp and chilly, there’s a smoother grain to the midrange and treble, whereas nonetheless permitting for full distillation of all frequencies. (The claimed complete frequency response is 10 Hz to 41.5 kHz.)
The 660S2 construct on that sound with an additional drop of amber within the sound, for much more saturated coloring that’s most pronounced within the low finish. The bass stands out as the largest cause to contemplate these over extra inexpensive fashions within the collection. Dropping the needle on hip-hop and digital tunes unleashes an added rush of foundational energy, and it may be lots of enjoyable to take heed to.
The primary groove in Biggie’s “Hypnotize” is a laser stick of thump with distinctive stability. It’s a funkier sound than the growth you’ll get from low cost bass bombers, virtually rewriting the general really feel with a jazzier taste. Equally, Too Brief’s “Cash within the Ghetto” has a candy, push-button punch to the principle kick that’s expertly articulated. These aren’t my regular go-to tracks for these sorts of headphones, however they helped to set the stage and sounded nice doing it.
The Chemical Brothers’ “Go” is an much more intriguing take a look at, once more showcasing the 660S2’s bass abilities whereas additionally highlighting their lightning-fast transient response. The music’s kick drum is carved with a deep texture of echoed reverb that expands like a bubble on the middle picture. The superb instrumental spacing allows you to roam freely via the dimensional soundstage, from the synth that sweeps via the stereo picture forward of the refrain to the build-up on the instrumental breakdown that looks like an imminent rocket launch.
Even the kick drum in Maxwell’s Silver Hammer has some additional thump to it, offering a extra raucous, but nonetheless refined trip than you’ll get from others within the HD 600 collection or past. I want the 6XX’s extra impartial take for such tracks, nevertheless it wasn’t a detriment to the expertise.
Elsewhere, you’re getting the identical form of lyrical readability and refinement that first endeared me to the HD 6XX. Reverb tails echo into oblivion; piano tracks allow you to estimate each the room dimension and mic placement—the nerd in me was asking, “Was that an open-lid close-up of a grand summed down with the room mic?” (I feel it was). The distorted guitar in ELO’s is so textural and visceral, it provides me the chilly fibrous crunch of biting right into a popsicle.
Even podcasts are extra richly portrayed, letting you hear not solely how shut the voices are to the mic beat by beat, however deeper particulars like whether or not Sean Hayes had dairy forward of the Smartless Jon Favreau interview (he positively did).
It’s all, in a phrase, wonderful. However to my ears, the HD 660S2 aren’t a lot an enchancment over different headphones within the collection as a barely totally different take. Fabulous headphones all, I’m most fascinated by the perfect worth. As I write this, you will get the unique 660S at $320, to not point out the shockingly inexpensive 6XX at $219. What’s extra, I discovered the 6XX to be the comfier of the 2 I’ve tried, which is a serious consideration for prolonged listening classes.
In the event you’re excited concerning the additional bass, the richer saturation, and even the tighter flex in your noggin, there’s audiophile surprise available within the HD 660S2. Whether or not that’s price the additional coin is as much as you and your pockets.
