Sennheiser HD 599 Review: Open-Back Headphones Worth It?
Looking for a smooth, relaxed sound for your music sessions? The Sennheiser HD 599 might be your answer.
These open-back headphones deliver a warm and lush sound signature. They create a wide soundstage that makes you feel like you’re in a live concert.
Comfort meets performance with this pair. You can wear them for hours without any discomfort.
The HD 599 offers precise imaging and good bass response. However, they are not perfect. The open-back design means no noise isolation, and the construction leans on plastic.
In this review, we will dive deep into the pros and cons of the Sennheiser HD 599. We will also compare it with top competitors like the HD 560s and Philips Fidelio X3. Let’s find out if this headphone suits your needs!
In a Nutshell
-
Open back design lets sound breathe naturally, but it also means zero noise isolation. These are best for quiet rooms, not noisy commutes.
-
The build relies on plastic heavy construction. It feels solid enough for daily use, but durability stays average over time.
-
At just 0.57 lbs, the HD 599 stays light on your head. The 7.2 x 6.1 x 3.2 inch frame fits most head sizes comfortably.
-
There is no built in microphone. So these headphones suit music listening, not calls or gaming chats.
-
Bass lovers should note the mid bass emphasis. Sub-bass feels a bit limited, and the upper-mid bass can sound slightly exaggerated.
-
Compared to the Sennheiser HD 560s, the HD 599 feels warmer and smoother. The HD 560s leans more neutral and treble-forward for detail lovers.
-
If you want a relaxed, laid-back listening session at home, the HD 599 fits that role well.
Design and Build Quality
The Sennheiser HD 599 feels light and unobtrusive during extended listening sessions. At just 0.57 lbs, these headphones won’t weigh down your head or cause fatigue over hours of wear.
The design employs plastic construction throughout, which keeps the weight down but affects long term durability. The materials feel adequate for casual home use, though they won’t match premium metal builds found on higher end models. The headband uses a simple adjustment mechanism that works smoothly without complications.
The open back design is a defining feature here. Sound waves escape freely from the rear of the ear cups, creating a natural and spacious listening experience. This design choice means the HD 599 delivers impressive soundstage depth and width. You get precise imaging that places instruments and vocals in clear positions around your head. The tradeoff? These headphones offer zero noise isolation.
The ear cup design sits comfortably on most head shapes. The padding provides soft contact without creating a seal, which aligns with the open back philosophy. This approach makes them ideal for home listening where sound leakage matters less.
The cable connection is fixed and wired only. There’s no wireless option or detachable cable, which simplifies the design but limits flexibility. The proprietary Sennheiser transducer technology sits inside each cup, handling the sound reproduction.
One notable absence is a built in microphone. If you need to take calls or use voice commands, you’ll need external solutions. This omission keeps the design focused on audio quality rather than versatility.
The overall construction feels straightforward and honest. Sennheiser prioritized comfort and sound delivery over premium materials or complex features. The plastic frame and simple mechanics mean fewer things can break, though durability depends heavily on how carefully you handle them.
For studio work or critical listening at home, the build quality proves sufficient. For travel or outdoor use, the open back design and plastic construction make them less practical. The HD 599 targets listeners who value sound quality and home listening comfort above all else.

Sound Performance and Soundstage
The HD 599 excels in creating a spacious listening environment. The open-back design allows sound waves to move freely, which produces a wide and deep soundstage that pulls you into your music. You’ll notice instruments spread across a broad field rather than sitting inside your head.
Imaging precision stands out as a real strength here. Each sound element occupies a clear, distinct position in the stereo field. Vocals stay centered while guitars and drums find their own space. This clarity makes it easy to follow individual instruments even in complex arrangements.
The warm sound signature defines the listening experience. Mids and lows blend together smoothly, creating a lush, enveloping tone that feels inviting rather than clinical. This approach works especially well for genres like jazz, classical, and acoustic music where smoothness matters more than raw detail.
Bass response delivers impact without harshness. The mid-bass emphasis gives drums and low-end instruments a forward presence. You’ll feel the weight and punch of kick drums clearly. However, the sub-bass rolls off somewhat, so deep rumbling sounds don’t extend as far as some listeners might want.
The treble region stays relaxed and non-fatiguing. Higher frequencies don’t leap out or irritate your ears during long sessions. This makes the HD 599 a comfortable choice for marathon listening without listener fatigue.
Sound quality remains consistent across different volume levels. Quieter passages retain detail while louder moments stay controlled. The transducers handle dynamic swings smoothly without distortion.
One trade-off exists with the open-back design. Sound leaks outward, so nearby people hear what you’re playing. This also means external noise enters freely. If you need isolation or privacy, these headphones won’t provide it.
The overall sound profile leans toward musicality over accuracy. You’re getting a presentation that prioritizes enjoyment and relaxation rather than analytical detail. For casual listening at home, this approach shines. For critical studio work requiring neutral response, the HD 599 takes a back seat to more reference-oriented alternatives.
Comfort and Wearability
The HD 599 prioritizes comfort during long listening sessions. The headband distributes weight evenly across your head. Padding on the headband feels soft and supportive, so you won’t experience pressure points after hours of wear.
The ear cups feature a generous design that accommodates various ear sizes. They sit naturally around your ears without clamping too tightly. The open-back construction allows airflow, which prevents heat buildup during extended use. This breathability makes them ideal for home listening marathons.
At just 0.57 lbs, these headphones feel almost weightless on your head. You’ll forget you’re wearing them after a few minutes. The lightweight design comes from the plastic-heavy construction, which some might view as a trade-off. However, this material choice directly enables the comfortable, unobtrusive fit.
The headband adjustment mechanism works smoothly and locks into place securely. You can find your ideal fit without fussing with the settings. The ear cup swivel allows natural movement, so they adapt to your head shape rather than forcing you into a fixed position.
One consideration involves the fixed wired cable. Since there’s no detachable option, you need to manage the cable carefully during wear. The cable doesn’t tangle easily, and its length gives you reasonable freedom of movement around your listening space.
The open-back design influences comfort in another way. Sound leakage means you won’t isolate from your surroundings, but this also means external noise won’t build up inside the ear cups. You stay aware of your environment, which some listeners prefer for casual home use.
Glasses wearers should find these comfortable too. The ear cup design provides enough space without excessive pressure against frame arms. The relaxed fit accommodates most head shapes without requiring adjustment periods.
Overall, the HD 599 excels in wearability. These headphones reward extended listening sessions with consistent comfort. The lightweight construction and thoughtful padding combine to create a listening experience where the headphones themselves fade into the background. You focus on your music, not on how the gear feels.

Open-Back vs. Closed-Back: What You Need to Know
Open-back headphones let sound waves pass through the ear cup. This design creates a natural, spacious feel. Closed-back headphones seal the sound inside the cup instead.
The Sennheiser HD 599 uses an open-back design. This choice affects how you experience music in meaningful ways.
Sound Characteristics
Open-back headphones produce a wider soundstage. The HD 599 delivers this advantage well. You hear instruments spread across a larger space. Closed-back models compress the sound closer to your ears.
The HD 599 also offers better imaging precision. You can pinpoint where each sound comes from in the mix. Closed-back headphones struggle with this clarity.
The Trade-off: Isolation
Open-back design means zero noise isolation. Sound leaks out from the ear cups. People nearby will hear what you’re listening to. Closed-back headphones contain the sound better.
This matters if you work in shared spaces. The HD 599 works best in quiet home environments. You won’t block outside noise either. Traffic, conversations, and background sounds still reach your ears.
Which Style Suits You?
Choose open-back if you value soundstage and comfort. The HD 599 excels here. You get that natural, airy listening experience. The open design also reduces ear fatigue during long sessions.
Choose closed-back if you need isolation. Closed models block external noise. They also prevent sound leakage. These work better for commuting or shared offices.
The HD 599 Philosophy
Sennheiser designed the HD 599 for home listening. The open-back approach fits this purpose perfectly. You get exceptional soundstage without fighting ambient noise indoors.
If you move between environments frequently, closed-back might suit you better. The HD 599 commits fully to the open-back experience. It doesn’t compromise with hybrid designs.
Consider your listening space first. Home listeners gain everything from open-back design. Commuters and office workers should explore closed-back alternatives instead.
Best Use Cases and Audio Scenarios
The Sennheiser HD 599 shines in specific listening situations where its strengths matter most.
Music lovers who enjoy acoustic genres find these headphones exceptional. The warm sound signature and precise imaging bring out the nuances in jazz, classical, and folk recordings. Instruments sound natural and well-separated across the soundstage. Vocals feel intimate yet spacious at the same time.
These headphones work wonderfully for casual home listening sessions. You can wear them for hours without fatigue or discomfort. The relaxed treble means you won’t experience listening fatigue even during extended use. This makes them ideal for background music while working, reading, or relaxing.
Gaming represents another strong use case. The wide soundstage helps you pinpoint directional audio cues in competitive games. Imaging precision means you can detect footsteps and environmental sounds with good accuracy. The comfortable fit supports long gaming marathons without pressure points.
Movie watching benefits from the HD 599’s strengths too. Dialogue comes through clearly thanks to the balanced midrange. Action scenes gain impact from the mid-bass emphasis. The open soundstage makes cinematic audio feel more immersive and expansive.
However, these headphones don’t suit every scenario. Skip them if you need noise isolation for commuting or office work. The open-back design lets surrounding sounds leak in and out freely. You’ll hear ambient noise, and others nearby will hear your audio.
They’re not ideal for critical studio monitoring either. While build quality suffices for casual listening, the warm sound signature colors the audio rather than revealing it neutrally. Professional mixing requires headphones with more accurate frequency response.
Portable use presents challenges since they’re wired and open-backed. Moving between noisy environments means constant audio distraction. The fixed cable also limits mobility compared to wireless options.
The HD 599 excels as a dedicated home listening tool. They reward you in quiet, controlled environments where you can appreciate their soundstage and comfort. They’re perfect for people who prioritize musicality and relaxation over portability or noise isolation.

Who Should Buy It
The Sennheiser HD 599 works best for specific listener types and situations. Let me break down who gets the most value from these headphones.
Music enthusiasts at home should seriously consider the HD 599. If you spend hours listening to vinyl, streaming, or your personal music collection indoors, these headphones deliver. The warm sound signature keeps listening sessions comfortable for extended periods. The precise imaging means you hear exactly where each instrument sits in the mix. Acoustic music, jazz, and classical recordings shine through the wide soundstage.
Casual gamers find the HD 599 particularly rewarding. The open-back design creates a spacious audio environment that helps you detect directional cues in competitive games. You hear footsteps, gunfire, and environmental sounds with clear placement. However, serious esports players might prefer closed-back models that block outside distractions.
Home theater viewers enjoy the HD 599’s strengths too. Movies feel immersive with the wide soundstage. Dialogue remains clear and centered. Action sequences benefit from the mid-bass emphasis that adds punch to explosions and impacts.
Audiophiles seeking a relaxed listening experience appreciate these headphones more than critical monitoring professionals. The warm, smooth character suits casual enjoyment rather than studio work. If you analyze music for production or mastering, the HD 599’s coloration might frustrate you.
People who wear glasses get bonus comfort. The lightweight design and open-back construction mean less ear pressure during long sessions.
The HD 599 doesn’t suit commuters or travelers. The open-back design means everyone around you hears your music. You also hear all ambient noise. If you move between offices, coffee shops, and public transport, you need isolation instead.
Office workers in shared spaces should look elsewhere. These headphones leak sound significantly. Your colleagues will hear your music clearly. Closed-back alternatives work better for professional environments.
Listeners seeking powerful sub-bass might feel disappointed. The HD 599 emphasizes mid-bass rather than deep low frequencies. Bass-heavy music genres work fine, but you won’t feel extreme rumble on tracks that demand it.
Choose the HD 599 if your primary listening happens at home in a quiet space where you value comfort and soundstage over isolation and portability.
Final Verdict
The Sennheiser HD 599 stands out as a reliable choice for anyone who values comfort and rich sound. It brings warmth and detail together in a way that feels natural.
If you compare it with the Sennheiser HD 560s, you get a different flavor. The HD 560s leans neutral and treble forward, while the HD 599 stays warm and relaxed.

Moondrop Void is another contender in this space. Yet the HD 599’s soundstage and imaging give it a unique edge that many listeners appreciate.
Sennheiser’s proprietary transducer technology plays a big role here. It shapes the open airy sound that makes these headphones so pleasant to use.
This pair does not try to be everything for everyone. It focuses on comfort and musical enjoyment rather than chasing every audiophile trend.
That focus makes the HD 599 a smart pick for relaxed listening sessions. It rewards patience and long term use over quick critical analysis.
Think about your daily habits before deciding. If you want something that fits well and sounds inviting, this headphone delivers exactly that.
The open back design and mid bass emphasis define its personality. Once you accept these traits, the listening experience becomes genuinely enjoyable.

We recommend it for listeners who want comfort, warmth, and detail without complications. It fits a wide range of ears and listening styles with ease.
This headphone may not top every technical chart. But it wins where it matters most, in everyday enjoyment and long term comfort.
