SENNHEISER HD 820

The new audiophile standard for closed-back headphones
For audiophiles there wasn’t any doubt: When it came to circumaural headphones the very best sound required an open back design. This axiom has now been rendered obsolete by the youngest member of the Sennheiser Audiophile Range: The closed dynamic HD 820 employ an innovative technology that makes them sound breathtakingly transparent and natural. Developed and made in Germany, they offer an incredibly realistic, natural sound field and also stand apart by the extraordinary attention given to every detail of their design. Their soft comfortable microfiber ear pads are hand crafted, providing excellent attenuation of ambient noise, while the robust metal headband includes an inner damping element. Get ready for an unparalleled listening experience.

Into the great wide open
Vivid, wide, transparent, natural. The sound field of the HD 820 is wide open. Which is not what you would expect at all from closed circumaural headphones. With the HD 820 you can explore and rediscover your music in absolute reference-class quality without intruding on the aural comfort zone of others. Thus, the HD 820 not only open up the sound field, but also new places and opportunities for you to enjoy your music.

The technology of transparency
The breakthrough transparent performance of the HD 820 has been achieved through a special innovation: Their legendary Sennheiser Ring Radiator transducers are fitted with unique glass covers. Revealing the great look of the technical component within, this visually striking feature was actually developed wholly in service to the sound: The concave glass reflects the sound waves from the rear of the transducer to an absorber, which results in minimal resonance. Thus, the sound waves are effectively “gone” like they would be in open headphones.

An all-star team of excellent components
Made in Germany, the HD 820 stand apart also because of the extraordinary attention that is given to every detail: From the extra comfortable handcrafted ear pads that insulate the listener from ambient noise, to the silvercladded OFC cables and gold-plated plugs, to the robust metal headband with an inner damping element. This package offers an unparalleled listening experience, which can even be improved by the Sennheiser HDV 820 amplifier for dynamic headphones – the perfect companion to the HD 820.

Audiophile connectivity
Only what gets in can eventually get out. That’s why the HD 820 come with a specially tuned symmetrical, impedance-matching cable with low capacitance and a balanced 4.4 mm gold plug, which offers superior characteristics in contact resistance, and thus in sound.

The look of superior quality
A well-conceived audio component always looks good – inside and out. With their unique glass covers the HD 820 display all the evidence to prove this. They are an aesthetical timeless classic and a natural technical beauty.

 

ASTELL & KERN KANN ALPHA

KANN ALPHA, the third product in the KANN series of Digital Audio Players. While the goal of the Astell&Kern KANN line is to provide ultra high power output to drive any headphone or IEM, KANN ALPHA has not forgotten the essence of being a portable DAP, so you can enjoy a near-perfect sound experience wherever you are.

  • The first Astell&Kern DAP to feature a 4.4mm balanced output
  • Complete separation of balanced lines to provide noise-free output
  • Crosstalk of 141dB and top-notch audio performance through a complete circuit redesign
  • Powerful 12Vrms ultra-high output support
  • 14 ½ hours of continuous playback
  • Equipped with the latest version of Bluetooth, Bluetooth 5.0
  • Artistic design and ultra-precision metal shaping technology that Astell&Kern has perfected

 

First DAP to Feature 4.4mm Balanced Output Port, Completely Noise-Free

The newly introduced feature of the 4.4mm balanced output port is exciting, however, the most important part is how we implemented it.
Unlike other manufacturer’s products, KANN ALPHA has physically separated the 2.5mm and 4.4mm outputs using micro relays.
When 2.5mm and 4.4mm structures are connected only to the mute circuit they do not prevent noise interference that may occur because each signal is not properly blocked.
KANN ALPHA boasts noise-free output because we built in an independent structure that completely blocks interference from outputs that are not being used and to be switched off therefore preventing the noise from occurring.


Gold PVD Coating Method

In order to minimize contact noise from the output, a gold PVD coating method is applied to the headphone connector instead of the typical rings used by other products. This improves both design and function.
By adopting NDICS' Pentaconn 4.4mm connector, KANN ALPHA not only satisfies the requests of users, but the implementation boasts excellent quality and durability.


The Highest Level Of Channel Separation (Crosstalk)

KANN ALPHA boasts excellent performance measurement for crosstalk. Channel crosstalk is how much signal leaking there is between the L and R channels.
The higher the crosstalk number, the better the separation between channels and the deeper and wider the sense of space that can be felt.
As evident with the newly developed audio circuit design, KANN ALPHA features a never before seen Crosstalk measurement of -141dB(High Gain), which is unmatched by any other portable audio products in its class.


Powerful 12Vrms Output With 14 ½ Hours of Continuous Playback

KANN ALPHA supports the same powerful 12Vrms output as the existing KANN CUBE, however the player has been optimized to be more compact. This is achieved through the miniaturization of numerous parts such as resistors and capacitors, by rearranging various components and through circuit optimization. This resulted in the modification of more than 60 parts during the development process.

Ultra-small tantalum capacitors, which were developed exclusively for Astell&Kern through a collaboration with Matsuo Electric in Japan to meet our high performance requirements, supply stable power to the player and suppress electrical noise.

This redesigned power circuit used in KANN ALPHA also allows us to achieve 14 ½ hours of continuous playback.


Equipped With Bluetooth 5.0 and Support for Wireless 24-Bit Qualcomm® aptX™ HD , LDAC Codecs

KANN ALPHA is the first Astell&Kern player to use Bluetooth 5.0. The latest Bluetooth version provides high sound quality with the convenience of wireless playback to headphones and IEMs. Bluetooth 5.0 features faster transmission speed and greater range compared to Bluetooth 4.2, therefore providing a more stable wireless connection.
Both LDAC and Qualcomm® aptX™ HD is supported to provide audiophiles with the best wireless sound possible. The high-quality sound that Astell&Kern is known for can now be heard when using Bluetooth earphones, headphones, and speakers.


Customize Your Sound

With KANN ALPHA, you can enjoy the fun of creating your own customized sound by selecting among various DAC filters provided by the DAC manufacturer.


Real-Time Information Confirmed by Light

KANN ALPHA features a LED volume wheel which displays various playback information, including volume level and bit-rate of the track currently playing.
* LED can be turned on or off according to user setting.
