Sennheiser HD 820 Review : A closed Back Headphone.

Sennheiser HD 820

Hello / Greetings To Everyone, So Today I am going to put my true views on Sennheiser HD 820 Review.

The Sennheiser HD 820 is the latest high-quality headphones from German Hi-Fi specialists Sennheiser. They have a lot in common with the popular HD 800 and HD 800S open back models, but this time the company opted for a closed design.

Here, the company’s new earbuds have a glass panel, which by default gives them better isolation and better mid-bass presence. It, however, sacrifices the openness and clarity you’ll find in open-back headphones. One such example comes in the form of Sennheiser’s other flagship models, the HD 800 and HD 800S, which are standard headphones for many. The question is, has the German company set the bar too high compared to previous iterations?

The Sennheiser HD 820 is arguably the best closed back in-ear headphones that have ever been. They are as convenient as the HD 800 and HD 800S and come in a convenient package of three 3.6m interchangeable cables, each with a different 4.4mm balanced connector, XLR connector, and 6.3mm unbalanced connector.

But while the HD 820’s superior design and sound performance cannot be denied, their sound cannot be as impressive as their open-back siblings. Therefore, whether they are right for you or not will depend on your priorities.

Equipments With Sennheiser HD 820

The Sennheiser HD 820 headphone box contains a sturdy storage case, microfiber cloth, instruction manual, three detachable cables and a USB stick containing a PDF copy of the manual and customized frequency specifications.

The connecting cables are the same length and differ in characteristics:

  • unbalanced cable with a 6.35 mm plug;
  • balanced cable with Pentaconn TRRRS connector 4.4 mm;
  • balanced 4-pin cable with XLR-4 connector.

Each cable is flexible enough not to distort sound while listening to melodies. The price of one cable ranges from 150$ to 250$.

Design : Sennheiser HD 820

At first glance, the Sennheiser HD 820 has the same design as the other 8XX headphones. The adjustable, soft, microfiber-coated bow is reminiscent of the H800S, down to the embossing and serial number on the top.

On closer inspection, the differences become apparent. Instead of an exposed silver mesh, the manufacturer supplied black ribbed panels. The calyx circumference is flatter, without outward bending. The rear of the transducer is protected by concave glass discs. The glass is visually distinguished not only by its convex profile, but also by its high degree of gloss and resistance to fingerprints.

The result is a stylish, high quality and reliable design. See-through Gorilla Glass deflectors add visual appeal. This is how headphones cost 2000$ should look like.

Comfort

Now it’s time to talk about the comfort of Sennheiser HD 820 is Soft, hand-crafted microfiber ear cushions, approx. 26mm in size, provide excellent ambient noise suppression. The HD 820 earbuds fit snugly around your ears and hold much better than the HD 650 or Focal Utopia.

The product weighs 360 g, which is 10% more than the HD 800, but both models are equally comfortable.

Most closed-back headphones generate heat with prolonged use. The Sennheiser HD 820 does not have this problem. They can be comfortably worn for hours in the scorching summer sun.

Overall it is very comfortable and giving complement to its high price ticket.

Sound Quality

The right sound setting will allow you to enjoy moments that are only available during studio recording. A decent level of bass line, stunning low frequencies and a intelligible midrange open up new horizons in the sound space.

From the first minutes of listening to a song, it is unmistakable that the headphones belong to the HD 8 series.

The sub-bass sounds are powerful yet controlled, without the roaring lows found in the Abyss AB-1266 Phi CC or Fostex TH900 Mk2 headphones.

Mein Herz brennt from Rammstein or Paradise Circus from Massive Attack will really appreciate the bass performance. When played in the HD 820 headphones, even an inexperienced listener will understand how clear and deep these songs can sound.

There is no bass in the middle range (a common problem with closed-back headphones). The dip in the frequency response between 250 and 300 Hz is probably responsible for the clean sound transition and integration between the upper bass and lower midrange.

Bass boosting with the EQ program does not result in midrange distortion. By comparison, boosting bass without EQ adjustments on the TH900 Mk2 and Sony MDR-Z1R leads to midrange issues.

The main point of a closed headphone versus an open headphone is to create a realistic sound picture and abstract from external sounds. Many people prefer to use the device because of its more efficient bass delivery or for listening to certain types of music genres.

However, over-ear headphones are generally chosen for complete privacy. The Sennheiser HD 820 provides sufficient isolation to help you listen to songs at acceptable levels of around 80 dB.

And headphone is mostly about sounds and Sennheiser HD 820 is one of the greatest in the sound thing.

Technology: Sennheiser HD 820

Like the previous model, the HD 820 is equipped with a unique “Ring Radiator” transducer with a nominal impedance of 300 ohms and a similar sound pressure level of 103 dB. However, they now have glass acoustic baffles built into them , which are designed to diffuse and redirect sound waves from the back of the transducer to the absorber.

This technological innovation is fundamentally different from traditional types of closed-back headphones, including models from Sennheiser, which use different damping materials to absorb energy from the back of the head. The HD 820 minimizes the effect of unwanted resonances on sound.

The unique solution creates the sound image inherent in open headphones. Of course, this technology will be the focus of the review more than once when discussing sound characteristics.

Conclusion

So lastly, The Sennheiser HD 820 are the best closed-back headphones at the time of writing. They have a high cost, which is easily compensated by sound quality.

Don’t expect the same sound from the HD 800, except for excellent ambient noise cancellation. When buying, you will definitely have a choice between the HD 820 and 800, since the latest model has a slightly better sound quality and three times less price.

If you need a well-balanced, technically superior musical closed-back headphone, the HD 820 should be preferred. Otherwise, you might want to consider the earlier Sennheiser, Sony MDR-Z1R or ZMF Eikon models.

Overall if you have good budget and fan of Sennheiser headphones then you should buy this amazing piece 😍.

Thank You!!!
