Sennheiser HD 599 Review: Audiophile Sound on a Budget!

#ad Sennheiser HD 599 Around-Ear Open Back Headphones – A Sophisticated Listening Experience

When it comes to premium audio gear, Sennheiser has long been a trusted name, and the HD 599 is a perfect example of why. Sitting comfortably in the brand’s mid-range lineup, the HD 599 offers a balance of elegant design, comfortable wear, and outstanding audio quality that punches well above its price bracket. After spending a good amount of time with these headphones, it’s clear that Sennheiser has crafted a truly enjoyable product for audiophiles and casual listeners alike.

Design & Build Quality

Right out of the box, the first thing that strikes you is the unique ivory finish. While most headphones play it safe with black or grey, the HD 599 opts for a creamy, off-white shell with contrasting brown earpads and headband cushioning. It’s a bold choice, but one that lends a premium, almost vintage aesthetic that feels right at home in a more refined setting.

The headphones are predominantly made of plastic, but not the flimsy kind. It feels solid and well-constructed, with a durable matte finish that resists fingerprints and smudges. The metal detailing on the headband and around the earcups adds a subtle touch of class without going overboard.

The padding is generous and covered in a velour-like material that’s soft and breathable, making these a dream to wear for long listening sessions. The headband is adjustable, and the clamping force is just right — firm enough to stay in place without creating pressure points. Overall, it’s clear that comfort was a top priority in the design of the HD 599.

Open-Back Design and Fit

Being open-back, the HD 599s are not meant for on-the-go listening. They’re best enjoyed in a quiet, controlled environment where you can truly appreciate the nuances in your music. The open-back design allows air and sound to pass through the earcups, resulting in a more natural and spacious soundstage. However, it also means that sound leakage is noticeable — people around you will be able to hear what you’re listening to, and you’ll be able to hear ambient noise.

These are not studio headphones in the sense of isolation or monitoring, but they’re ideal for home use, especially if you're keen on immersing yourself in your favourite albums or exploring the subtleties of classical, jazz, or acoustic genres.

Sound Quality

The HD 599 delivers what Sennheiser does best — a smooth, warm sound signature that’s easy on the ears while still retaining detail and clarity. If you’re coming from more consumer-focused headphones with boosted bass or overemphasised treble, the HD 599 might sound more neutral at first. But give it time, and you’ll likely fall in love with its refined, open sound.

The bass is present and well-rounded, but not overbearing. It doesn’t slam or thump aggressively, which might disappoint bass-heads, but it’s controlled and accurate. It provides enough depth to make drums and basslines feel natural without muddying the mids.

Speaking of mids, this is where the HD 599 really shines. Vocals are rich and lifelike, with a smoothness that makes long sessions non-fatiguing. Guitars, pianos, and strings are rendered beautifully, giving each instrument room to breathe within the mix. It’s a headphone that rewards attentive listening.

The treble is crisp and clear, though never piercing. It strikes a nice balance between detail and smoothness, helping to round out the sound signature. The overall presentation feels airy and wide, thanks largely to the open-back design. Soundstage is impressive for this price range — you get a genuine sense of space and direction, which enhances everything from orchestral music to ambient electronica.

Performance with Different Genres

What’s particularly enjoyable about the HD 599 is its versatility. It handles a wide range of genres with poise. Classical music sounds expansive and detailed, letting you hear the subtle movements of a string section or the distant shimmer of a cymbal. Jazz feels intimate and warm, with every note ringing true.

Rock and indie fare well too, with vocals and guitars taking centre stage without being overwhelmed by bass or treble. For electronic music, especially ambient and downtempo styles, the HD 599 performs admirably, creating a spacious soundstage that allows layers and effects to unfold naturally.

However, if your library is full of bass-heavy hip-hop or EDM, you might find the low-end a bit too reserved. These aren’t headphones designed to shake your head with booming sub-bass, but rather to offer a clean and balanced listening experience.

Connectivity and Accessories

The HD 599 comes with two detachable cables — one 3-metre cable terminated in a 6.3mm jack for home stereo equipment, and a shorter 1.2-metre cable with a 3.5mm plug for use with laptops, phones (with an adapter, if needed), or portable devices. It’s a welcome inclusion, giving you flexibility depending on your setup.

Both cables feel sturdy and well-made, and the inclusion of a 6.3mm to 3.5mm adapter is a thoughtful touch. The cables connect to the headphones via a 2.5mm twist-lock mechanism, which ensures a secure connection while still being easy to detach for storage or transport.

While there’s no in-line microphone or remote control, that’s expected for this style of headphone. These are clearly designed for home listening rather than commuting or mobile use.

Comfort Over Time

Comfort is a standout feature of the HD 599. Whether you’re wearing them for a short burst or a multi-hour session, they never feel heavy or hot. The velour pads do a brilliant job of staying cool and breathable, even during extended listening.

The clamping force is gentle, and the lightweight build ensures there’s no strain on the neck or head. These are the kind of headphones you can put on and forget you’re wearing — which is exactly what you want when settling in for a deep listening session.

Who Are They For?

The Sennheiser HD 599 is ideal for anyone who wants to experience high-quality audio at home without stepping into the world of high-end audiophile gear. They’re a superb entry point into open-back headphones and provide a sonic experience that far exceeds what you’d expect at this price point.

They’re perfect for:

• Home listeners who want an immersive, high-fidelity experience

• Music lovers who appreciate vocal and instrumental detail

• Audiophiles looking for a comfortable, relaxed sound signature

• Those who want open-back headphones for casual listening, gaming, or even light mixing

They’re less ideal for:

• Commuters or frequent travellers

• Users who require noise isolation

• Fans of very bass-heavy sound signatures

Final Thoughts

The #ad Sennheiser HD 599 is a beautiful piece of audio engineering. It brings together timeless design, excellent comfort, and a clean, spacious sound that’s genuinely rewarding. It may not have the bells and whistles of more modern or mobile-focused headphones, but it doesn’t try to. Instead, it sticks to doing what it does best: delivering rich, detailed sound in an incredibly comfortable and attractive package.

For anyone looking to take a step up from basic consumer headphones and experience a more audiophile-style sound without the associated price tag, the HD 599 is a compelling choice. It’s a headphone you’ll reach for time and again — not just because it sounds fantastic, but because it makes listening feel like a real occasion.
