Sennheiser RS 175 RF Wireless Headphones

OVERVIEW:
Dive deeper into legendary sound: Enjoy your music on a completely new level. An intimate, relaxed sound signature combines with outstanding precision and exceptional comfort — and now, extended sub bass — for a deeply moving experience.
Every high-end headphone has its own unique personality. What if you could only own one?: Ever felt goosebumps from sound so real, it was as if the source was in the room with you? The non-fatiguing HD 660S2 gives people who love music an intimate way to connect more deeply with their favorite songs and artists. Breathtaking resolution and precision take you closer than ever to instruments and vocalists. Yet the sound is natural and balanced, never harsh or brash. This warm, inviting signature combined with extended sub bass makes listening uniquely pleasant and rewarding. And with comfort this good, it practically begs you to keep going for endless sessions. That’s how HD 660S2 combines the best of many worlds to give you an intimate experience you won’t want to live without.
Double the sub bass heightens your listening experience: Traditionally, audiophiles don’t get too excited about sub bass. It can easily get sloppy or boomy and become a distraction. And that’s a shame — because there’s so much more to experience here than just the gut punch of a kick drum. Did you know the low B of a 5-string bass vibrates at 30.9 Hz? Or that the lowest note on a concert piano comes in at 27.5 Hz? And of course, extended sub bass makes bass-heavy genres sound fantastic, too. And that’s the magic trick here. In doubling the sound pressure at the very lowest frequencies, we’ve nevertheless retained extraordinary precision and balance throughout the sub bass, mid-bass, and beyond. Most impressive is how this affects the listening experience. Extension on the low end changes everything — by creating more space for the sound. Against a deeper backdrop, highs feel more brilliant, the soundstage deeper, emotions stronger.
Comfy slippers, your favorite jeans, the HD 660S2. Some things just feel awesome to wear: The velour earpads of the HD 660S2 can only be described as a tactile pleasure. With just 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, even for super-long sessions. The low total weight and ergonomic headband rule out any potential discomfort on top of your head as well. Combined with excellent build quality made in Ireland, you’ll quickly grow attached to a listening experience that’s as physically pleasing as the warm, non-fatiguing sound at its heart.
Some of the most neutral headphones in the world are a tough act to follow: The surround is now more compliant, too, dropping the resonant frequency to 70 Hz. Considerable effort also went into optimizing the airflow around the transducer. There’s more sensitivity over the entire frequency spectrum because the magnet´s air gap works more efficiently now. Taken together, these measures result in even greater precision, speed, and resolution — with double the sound pressure at the lowest frequencies.

Sennheiser HD 450BT ANC Headphones

OVERVIEW:
Engineered for absolute clarity: The HD 600 is the audio purist’s choice for reference playback. An instrument of Sennheiser’s passion for perfect sound, it is globally recognized as the standard for analytical high-fidelity listening - even 20-plus years after its release.
X-Ray Specs: The HD 600 was developed to give audiophiles an impartial scale of everything before it in the audio chain. Purpose-built to vanish when the listener presses “play”, the HD 600 is the benchmark reference headphone for both analyzing and enjoying your hi-fi setup. This disappearing act starts with an innovative, systematic approach to sound reproduction using transparency as the driving principle. Leveraging Sennheiser’s progressive production techniques and computer-based transducer optimization, it perfectly fuses the art of sound with the science of it.
Opening Up Your Mind: The foundation of the HD 600 transducer system is an acoustically transparent open-back earcup that lets every single sound wave expand freely - a Sennheiser innovation pioneered and perfected for the most natural personal listening experience.Sound emanating from our exclusive 42mm driver is free from turbulence and distortion thanks to a specialized acoustic silk that controls airflow—one of the finest materials available for this task—while requiring hand assembly. By using ultralight aluminum voice coils, the 38mm diaphragm exhibits rapid rest and response times for clinical detail that never sounds harsh or hyped. Across the entire audible spectrum of sound, this combination of driver size and integrity delivers an articulate response that is honest to the source—the kind of listening experience required to absorb the details with confidence. The 300-ohm impedance of the HD 600 presents a unified backdrop that allows the nuances in your music collection to leap forward like you have never heard before. Each transducer is measured against rigid standards for consistent performance across 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.
Quality Control: We worked tirelessly to build a headphone with the luxurious comfort and lasting durability audiophiles demand. The velour HD 600 padding is supple to the touch for extended listening at your hi-fi stack. Even the earcup grille pattern was crafted specifically for this transducer system, guaranteeing a pristine personal sound experience. The HD 600 is assembled in Ireland at a state-of-the-art production facility with the attention to detail required to handle a wide variety of acoustic materials. Our production tolerances are extremely tight, ensuring that your HD 600 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. Most parts on the HD 600 are modular, making it a dream to keep operational as the go-to reference headphones regardless of your listening space’s acoustics.
It’s All About Connection: Your HD 600 comes with a detachable, impedance-matched cable with ultra-low capacitance. The ¼-inch / 6.3mm stereo connector offers the audiophile-standard plug for connection to devices such as headphone amplifiers and A/V receivers, digital audio players, analog gear, and more. At 9.8 feet / 3m long, it offers unencumbered listening on gear deep within your shelves or in a favorite listening chair. A premium adapter is included to reduce the 6.3mm to 3.5mm / ⅛-inch for plugging into countless other audio devices.
