The Sennheiser HD 599, like the HD 598, deliver a comfortable critical listening experience. They're lightweight, not too tight on your head, and have a well-balanced audio reproduction. However, like most open headphones they're not suitable to use outdoors or in noisy environments.

Our Verdict

5.3 Mixed Usage

The Sennheiser HD 599 are critical listening headphones that aren't versatile enough for other use cases. They leak a lot, they don't block any noise in loud environments, and they're not portable enough to carry on you at all times. However, they deliver in the sound department with a balanced and open audio reproduction ideal for critical listeners.

Pros
  • Lightweight and comfortable design.
  • Great audio reproduction.
Cons
  • Sensitive to ambient noise, by design.
  • Leaks a lot of sound, by design.
8.0 Neutral Sound

The Sennheiser HD 599 are great headphones for neutral listening. They have a better Bass than the HD 598 and sound good with instruments and vocals. Their Soundstage feels spacious thanks to their open-back design, and overall they deliver a well balanced audio reproduction. However, the slight emphasis in high-bass/low-mid makes them a bit boomy and muddy with some tracks.

4.1 Commute/Travel

Subpar for commuting. The open design lets the loud ambient noise seep into your audio.

5.4 Sports/Fitness

Not intended for sports use. They're big, bulky and too unstable.

5.0 Office

Poor for office use. They don't block the office chatter and everyone can hear what you're listening to.

Style

The Sennheiser HD 599 do not change much design-wise from the HD 598. The headband has been slightly improved with a better padding and a more premium look and feel. The ear cups also have some minor changes, with more metal around the cups but a cheaper plastic grill when compared to the HD 598. However, apart from the silver branding on the HD 599, it's difficult to distinguish them from the HD 598 at first glance due to the similarity in their design.

The Sennheiser HD 599 are incredibly comfortable headphones to wear for long listening sessions. They have large oval ear cups that are well padded and fit comfortably around most listeners ears. The padding is coated with a microfiber fabric that's soft and feels nice on the skin. The headband is also amply padded and not too tight on the head. You will rarely feel any fatigue even after having the HD 599 on for hours.

Like the Beyerdynamic DT 770, the Sennheiser HD 599 are bulky and don't fold. Therefore, they're not portable and they're a bit cumbersome to carry around on your person without a bag. Unfortunately, they don't come with a good carrying case so they may get scratched or damaged if you just throw them in your bag with all your other things, which is slightly disappointing.

Build Quality

The build quality of the Sennheiser HD 599 is about the same as the HD 598, with minor changes to the headband. The headband is now covered with a more premium leather coating and there's a bit more metal used on and around the ear cups. However, the frame still feels a bit weak when compared to some other headphones especially at the hinges.

Design
Stability

The Sennheiser HD 599, like the HD 598 and the Audio-Technica ATH-M50x, are not stable enough for sports but should be fine for casual listening. They also have a detachable cable that will disconnect if it gets hooked on something unless you lock it into the ear cups. However, they're not made for sports and aren't as tight as some of the other models from Sennheiser so the ear cups will sway a lot and slip off your ears if used while running.

Excellent consistency. The Bass Range of our Over-Ear and On-Ear headphones are measured on 5 different human subjects, 5 times each. The Sennheiser HD 599 shows very good consistency in the Bass Range, since their open-back design allows them to rely less on an air-tight seal to create their low-end. The Treble Range also shows good consistency, but depending on the positioning, there could be up to 3dB of variance at 3KHz.

Very good Bass Range performance. Low-bass, which is responsible for low-end thump and rumble is slightly lacking. Also, high-bass is overemphasized by an average of 4dB, making the sound of these headphones noticeably boomy. See our recommendations for the best headphones for bass.

Very good Mid Range performance. Mid and high-mid are reproduced nearly perfectly. However, the bump in low-mid, which is the continuation of the high-bass overemphasis will make the Mid Range slightly muddy.

Excellent Treble Range performance. Low-treble is reproduced consistently and is within 1dB of our target which is very good. The small bump around 9KHz however, could make the sibilant sounds slightly sharp.

Poor Isolation. Due to their open-back design, it is natural for the HD 599 not to isolate well. They achieve no reduction up to 2KHz, and above that, they only achieve about 10dB of isolation, which is poor.

Poor Leakage. The significant portion of the leakage is from 400Hz to 20KHz which is a broad range. The overall level of the leakage is loud too, which is a consequence of the open-back design of these headphones.

Compared to other headphones

Sennheiser HD 598

The Sennheiser HD 598 and the Sennheiser HD 599 are both very good critical listening headphones, but the HD 599 are marginally better. Though they look pretty different, they’re nearly identical in terms of comfort and build quality. The HD 599 do sound a bit better, with less underemphasized bass, but the difference will likely be negligible for most. The HD 599 also seem to isolate the wearer better than the HD 598, but neither of them isolate very much since they’re both open-back headphones. They’re very similar headphones and your personal preference will matter most in your decision.

Audio-Technica ATH-M50x

The Audio-Technica ATH-M50x and the Sennheiser HD 599 are two great sounding headphones but should be used in different situations. The Audio-Technica pack a bit more bass, which is due to their closed-back design. They’ll be a better option than the Sennheiser if you’re looking for great sounding headphones to bring on the go. On the other hand, the open-back design of the Sennheiser will be better-suited for quiet listening environments, and they are very comfortable for long listening sessions.

Beyerdynamic DT 990 PRO

The Beyerdynamic DT 990 PRO and the Sennheiser HD 599 are both great headphones for critical listening, but the HD 599 are more comfortable for long listening sessions, while the DT 990 PRO are noticeably better-built and feel more durable, but feel tighter. Also, while both their sound profiles are very similar, the HD 599 might be slightly more open-sounding than the DT 990 PRO. The DT 990 PRO come with a non-detachable coiled cable while the HD 599 come with two thin and detachable audio cables.

Sennheiser HD 600

The Sennheiser HD 600 and Sennheiser HD 599 are very similar headphones in performance, and the HD 599 might offer better overall value. Their sound profiles are fairly similar, but the HD 599 are noticeably more comfortable and don’t feel as tight as the HD 600. On the other hand, they don’t feel as well-built as the HD 600. Some may find the HD 600 sound a bit more neutral.

Philips SHP9500

Both the Philips SHP9500 and the Sennheiser HD 599 are both very comfortable headphones that are great for neutral listening. The Sennheiser deliver more bass for those who prefer a bit of extra punch, but the Philips sound less boomy.

Beyerdynamic DT 880

The Sennheiser HD 599 and the Beyerdynamic DT 880 are both great critical listening headphones if you like a neutral sound, but they have different sound profiles. The Sennheiser sound warmer, but also muddier, while the Beyerdynamic have a brighter, but also harsher, sound. The Sennheiser are also more comfortable for longer listening sessions, but the Beyerdynamic feel much more durable.

Sennheiser HD 650

The Sennheiser HD 599 are slightly better headphones for neutral sound than the Sennheiser HD 650. The HD 599 are more comfortable, their sound profile is better-balanced and neutral, and their passive soundstage is slightly more natural-sounding and wide. However, the HD 650 feel a bit better built and their audio cable is much longer.

Audio-Technica ATH-AD700X

The Sennheiser HD 599 are better audiophile headphones for most people than the Audio-Technica ATH-AD700X. The Sennheiser have less low-bass roll-off, less intense presence across the mid-range, and a much better-balanced treble response. Most people also find them more comfortable, although the Audio-Technica are more lightweight and the unique headband design can help relieve pressure during long listening sessions.

Sennheiser HD 58X Jubilee

The Senneheiser HD 599 and the Sennheiser HD 58X Jubilee are very similar headphones with very small differences. The HD 58X has a slightly more accurate sound profile, but the soundstage of the HD 599 seems to be slightly more open-sounding. However, the HD 599 are noticeably more comfortable to wear for long periods.

Philips Fidelio X2HR

The Philips Fidelio X2HR are slightly better open-back headphones for neutral sound listening than the Sennheiser HD 599. The X2HR look and feel slightly better-built, and have a slightly better-balanced sound profile. On the other hand, the Sennheiser are more comfortable and feel slightly more stable on the head.

Beyerdynamic DT 770 PRO

The Sennheiser HD 599 and the Beyerdynamic DT 770 PRO are both impressive audiophile headphones that each serve their own purpose. The Sennheiser are open-back, so they get less bass, but have an otherwise very balanced, clear sound and open soundstage. The Beyerdynamic are closed-back, so their sound profile can differ a bit more from person to person, but they generally get a lot more bass, but can also sound a bit sharp.
