The Sennheiser HD 600 Review Of 2021

Introduction 

The Sennheiser HD600 could scarcely be more popular. They are most likely the most well-known headphones released in the last 20 years. Following the Sennheiser HD560 Ovation, the German company produced the HD580 in 1993, which served as the foundation for all subsequent open-back versions. 

The HD600 are cutting-edge headphones with exceptional sound quality and value compared to most of today’s options. 

To know more about these excellent headphones, please keep reading on our Sennheiser HD 600 Review.

The Sennheiser HD 600 

Sennheiser HD 600 Audiophile Quality, Open Hi-Fi stereo Headphones
  • Sophisticated design, elegantly finished in black and grey
  • High-quality, open metal mesh earpiece covers for an extremely transparent sound

What Is Inside The Headphone Box? 

Regrettably, Sennheiser has abandoned the really lovely, big container that used to accompany the HD 600 headphones in the new HD 600; the packaging is now similar to that of the DROP X Sennheiser HD 58X Jubilee.

The HD 600 still comes with a line that is quite identical to the one Sennheiser initially provided in the late 1990s, and it seems fairly flimsy and prone to tearing, especially when compared to the more durable wire that comes with the HD 650 or HD 660S. 

Specifications   

  • Driver Type: Dynamic Driver
  • Jack Plug: 3.5/6.3 mm stereo
  • Frequency Response: 12Hz – 40,500Hz
  • Sensitivity: 102 dB SPL/V
  • Headphone Type: Open-back, Over-ear
  • Impedance: 300 Ω
  • Cable Length: 3m
  • Weight: 260g

The HD600 is Sennheiser’s flagship model of open-backed, reflecting the pinnacle of the traditional architecture of moving-coil transducers. Its diaphragm design reduces standing waves and hence distortion, and it is powered by a lightweight aluminum voice coil in order to offer the greatest transient response possible. 

The vital magnet assembly makes use of extremely strong magnets of neodymium ferrous. The motor mechanism has been optimized to provide excellent sensitivity with a broad dynamic range while minimizing harmonic and intermodulation distortion. 

Sennheiser’s ‘correction of loudness diffusion,’ a type of equalization designed to make them sound much more closely matched that produced by speakers in some suitable acoustic settings, is incorporated into the design.

According to the specs, the sensitivity is 97dB/mW, the frequency response is 16-30kHz (at -3dB points), the distortion is less than 0.1%. At 300, its impedance is precisely in the usual range middle part, making it a simple load for all headphone amplifiers. 

These headphones are 260g in weight mechanically, but they put considerable stress on your skull around your ears – they are circumaural designs — of 2.5N.

Sennheiser is one of the few manufacturers who bother to describe this critical component of headphone comfort, but we doubt most readers can comprehend what 2.5N pressuring feels like. Then, let us add that those headphones initially seem ‘tight,’ yet they are sturdy – there isn’t have any propensity for your HD600s to slip off your head when you accidentally tilt the head down, making them excellent for dancing, reading, mixing, typing, editing, or engaging while listening in any mobile activity else! 

Design 

Some may find their look antiquated and evocative of the 1990s due to the “marble effect” blue coating the plastic, maybe they’re lovely. When it comes to headphones, we should not be bothered with looks. However, we completely understand why some individuals like having eye-catching stuff. 

Material 

This Sennheiser HD600 is primarily composed of plastic. However, it has a higher-quality plastic feeling that feels more premium in its hands than competitors like AKG K701 and  Beyerdynamic DT880. 

Its build quality is excellent, particularly it’s metal articulation among headband assembly and ear cups. 

External grills cover the driver’s enclosures, which may be readily bent if enough pressure is exerted; thankfully, they are detachable and repairable. Although the ear cushions are constructed of higher-quality velour, they will undoubtedly wear out only after a few years of heavy use. 

On the other hand, the standard cables are a little too affordable for a $300 pair. Its connections are very thin and brittle, and they might fail fast. This Sennheiser HD650 includes a thicker cord. All cables are compatible with the HD 580/600/650 series of Sennheiser headphones. 

Durability 

One of this model’s strongest qualities is durability. Each component is simply changeable and may be found on the internet. The HD600 is built of simple parts and may survive for a long time. The drivers may also be quite dependable. The oldest headphone pairs have been around for about 20 years and are still in great working order. 

This is a useful page on the many HD600/HD650 models. Older HD600/HD650 versions feature a dampening foam in black that covers over the driver, which is visible behind the exterior grills, whereas subsequent models usually have grey covers. 

We couldn’t discover a precise date for this color or material change, although it was most likely made between 2007 and 2009. 

Power Requirements 

The HD 600 has a 300-ohm driver with a 97db/MW rating, whereas the HD 650 has a 103db/MW rating. You will, without a doubt, require an amplifier to drive these and for them to sound correct. Most amplifiers should drive them cleanly since they sounded fine on entry-level sources like the JDS Labs Atom set to high gain. 

When it came to scaling with the source equipment, it scaled when combined with higher-end amplifiers. When driven by, say, the SPL Phonitor XE, the HD 600 and HD 650 experienced a pretty large and genuinely amazing boost in midrange and treble resolution, coming fairly close to the SPL Phonitor XE. 

When driven by, say, the SPL Phonitor XE, the HD 600, and HD 650 experienced a very large and amazing boost in midrange or treble resolution, approaching the degree of detail plus clarity you would like to expect from an LCD-2.

Comfort Zone 

We should consider the HD600 the pinnacle of comfort in over-ear headphones, plus some different models like the DT880 and K501 coming close. Said, you can wear these all day. 

Ear Pads 

Its oval shape is comfortable for most ears, with quite soft foam inside (around 2.5 mm). The non-round shape might be a little tighter on really big ears. Its velour is ideal for extended sessions, and especially more so in the heat. 

Weight Distribution And Headband 

At 270g, it is lighter than most open over-ear headphones that weigh between 300 and 400g. Its lightweight is well dispersed throughout the structure with a strong headband and four layers of thick foam ( about 1.5 cm). With time, this foam may lose its sponginess and thickness, necessitating its replacement item. 

Sound Quality

This Sennheiser HD600 offers among the clearest and natural presentations we heard throughout our audio trip! They have the potential to sound natural while maintaining a fairly balanced tone. The HD600 is also very near to neutral somehow, with coherence from its bass to its treble. 

Pros 

  • Lively sound of reference-quality 
  • Natural and neutral response
  • Extremely comfortable  
  • Dependable and simple to fix

Cons 

  • A little lacking of bass extension
  • Need more breadth
  • Straight cable

Bass 

At 100 Hz, there is a tiny but perceptible midbass bump, accompanied by a steady roll-off below 80 Hz. Contemporary music with a strong emphasis on bassline will sound fantastic on this HD600. Unfortunately, most other records will sound bass-light or slightly below the average bass quality when compared to standard headphones.

Back to the year, they were released, 1997, they had a significant impression when comparing themselves to the competitors at the time. The midbass weight of a Sony CD3000 or an AKG K501 is not the same. 

The bass quality is good: the distortion was scarcely noticeable, but the midbass plus upper bass mild boosts might give a sense of muddiness compared to a planar pair’s pure linear bass. 

Midrange 

Their midrange is lively and forward slightly. Each time you switch to this HD600 after spending time with other pairs, you will immediately be smitten by their personality and tone.

However, over time, you will grow less fond of genres with a higher density in upper-mids (or lower-treble) – about 3-5 kHz. In that area, this HD600 can be piercing and excessively high. 

The vocals as well as string instruments sound great, and an upper-midrange accent is offset with a slight emphasis of lower-midrange at 100-400hz. Mids sound will be full with no single tone flaw and no graininess. 

Treble 

The highs on the HD600 are superb, perfectly tuned, and free of sibilances. Nowadays, the “Sennheiser veil” was unquestionably fiction.

The lower treble was smooth for our ears’ health, yet it has enough vitality over 9 kHz to keep it from seeming overly muffled or missing air. 

Dynamics And Soundstage 

When properly amplified, Sennheiser HD600 offers a true soundstage or detail retrieval. Their presentation is highly interesting, and it is both frontal and open. 

Still, we wouldn’t describe them as laid-back. However, their characteristics and presence in their mids may cause them to sound a little misty on extremely mid-centric songs. 

Because of the 300 Ohm impedance scale nicely with high-end amplification, particularly OTL amplifiers like Bottlehead Crack, once connected to a smartphone, its bassline will be quite loose as well as the dynamics are more squeezed than usual that makes them sound boring. 

Comparisons Of Mid-Fi Headphones 

When you compare headsets, you will see that each has distinct strengths and limitations. However, if you can not purchase the HD600, then those headphones below may all be alternate versions.

AKG K701 Open-back 

AKG K701 Open-Back, Over-Ear Premium Studio Reference Class Studio Headphones
  • Extremely accurate and detailed sound with excellent transient response
  • Ultra-precise varimotion diaphragm for sparkling highs and deep bass, 10Hz - 39800Hz audio bandwidth

The AKG was a little more analytical, less melodic appeal, but a considerably broader and open presentation. Its bass punch is slightly thin, there is far much low-treble for you to like over time. 

AKG K712 Open-back

Sale
AKG K712PRO Open-Back, Over-Ear Premium Reference Class Studio Headphones, Sophisticated Open Technology, Revolutionary Flat Wire Voice Coil, Broad and spacious soundstage, Comfortable Design
  • Discover every nuance and detail - perfect for critical listening, mixing, and mastering wherever you are
  • Carefully-selected transducers and an open-back design cbmbine for a phenomenal soundstage

The AKG K712 are robust mid-fi headphones that have a good sound tone. AKG K712 provides a more precise bass with more punch or extension, even while sounding extra open, including more treble. Have you ever been an admirer of their midrange? It may sometimes sound fake and lacks genuine character. 

The Audio-TechnicaOver-Ear ATH-AD900X 

Audio-Technica ATH-AD900X Open Back Headphones, Black, 4.7 in*11.3 in*8.3 in
  • CCAW voice coils for delicate and expressive power. New large aperture (53mm) drivers with beautiful sound reproduction
  • Unique design of air distribution and sound propagation throughout the headphone structure. Open-back housing for a very airy listening experience

Audio-Technica AD900X sounded very wide and airy yet lacked bass punch and had a strange midrange. We can suggest them for playing games, but as a sole set of headphones for music – no way! 

The Beyerdynamic DT880 

beyerdynamic DT 880 Edition 250 Ohm Headphone
  • Circumaural, premium headphones for music enjoyment at home
  • Neutral highs and bass tones and excellent spatial reproduction

Those German-made headphones feature the greatest analytical-sound mid-fi. They have a broader sound than HD600, with a somewhat tighter bassline but significantly more mid-treble with a drier middle. We should not value them highly for genuine music-listening excursions. 

The Hifiman HE-400i Over Ear

HIFIMAN HE400i Over Ear Full-Size Plannar Magnetic Headphone
  • Single-ended planar magnetic driver provides superior soundstage and spatial imaging.
  • Increased efficiency of 93dB allows it to be driven with a modest size amplifier or can even be used with a portable audio player or smartphone.

Hifiman HE-400i sounds excellent and is among the few mid-fi options that we enjoy listening to. They offer far greater bass high-quality than HD600. Hifiman HE-400i has much more treble intensity and a somewhat less prominent middle but no strange peaks or troughs. 

The Philips Fidelio X2 

These X2 are very distinct from the others that have a fairly lively profile with powerful bass and a lot of treble excitement. The midrange is distant as well as recessed, with a broad picture. They are, in fact, an excellent companion to HD600.

Final Thought

So, we feel that the HD600 might sound veiled in contrast to other headphones in terms of the response. We also believe that the mind is a tremendously strong force and that our perception of sound may alter over time. 

But in case you want to enjoy music in a clearer and louder way, you can consider these subwoofers.

We must also consider the essential component: how it was recorded, processed, and mastered.

This is maybe the essential aspect of audio that no one in the audiophile community wants to talk about. 

They feature a balanced sound profile that isn’t overly analytical. These are incredibly comfy, simple to fix and maintain, not overly difficult to drive. 

These all are genre masters and will only be acceptable on tracks featuring sub-bass volume. That’s why we highly recommend them to you guys.

The overall trend of new high-priced headphones makes these even more tempting than they were years earlier. Go after them; you’ll use them for such a long period of time!
