Sennheiser Sennheiser HD 599 - Open Headphones, Special Review

The Sennheiser HD 599 Special Edition delivers near-audiophile sound and exceptional comfort for about $144. Its open-back design creates a wide, natural soundstage, but it leaks audio and offers no noise isolation. Build quality is fantastic. Skip these if you need a good microphone or plan to use them on the go. A top pick for dedicated, at-home listening.

Let's talk about the Sennheiser HD 599 Special Edition. These are open-back, wired headphones that have been around for a while, and they've developed a bit of a cult following. For around $144, you're getting a taste of what makes Sennheiser's 500 series so beloved: a focus on natural, spacious sound and all-day comfort. They're not trying to be everything to everyone. There's no Bluetooth, no active noise cancellation, and the microphone is an afterthought. This is a pure, simple tool for listening.

So who are these for? If you're someone who listens to music at a desk, in a quiet room, and values soundstage and detail over isolation and convenience, the HD 599 is a compelling option. They're fantastic for getting lost in an album, mixing music, or even just enjoying a movie without feeling like you have earmuffs on. The open-back design means sound leaks out and ambient noise leaks in, but that trade-off is what creates their signature airy, natural feel.

What makes them interesting now is the price. At their original MSRP, they faced stiff competition. But at this sale price, they punch way above their weight class in sound quality and comfort. They sit in a sweet spot between budget headphones and true audiophile gear, offering a gateway into better audio without requiring a separate amplifier.

The numbers tell a clear story. In our database, the HD 599 scores in the 96th percentile for sound quality and the 98th for build quality. That's exceptional. In practice, this means you get a balanced, detailed sound with a surprisingly wide soundstage for the price. The 38mm dynamic drivers and the open-back design work together to create a listening experience that feels less 'in your head' and more 'in the room.' Bass is present and clean, but it's not overpowering. Mids are clear and vocals sound natural. The high end is detailed without being harsh.

Where the performance gets real is in comfort and longevity. Scoring in the 89th percentile for comfort, these are some of the easiest headphones to wear for hours on end. The large, velour ear pads and lightweight design (255g) mean you'll forget they're on your head. And that 98th percentile build score isn't just a number. The plastics feel robust, the headband has a solid metal core, and the parts are user-replaceable. These are built to last a decade, not just a product cycle.

At their current street price of around $144, the HD 599 Special Edition is an absolute steal. You are getting sound and build quality that competes with headphones costing twice as much. The value proposition is simple: they sacrifice modern features like wireless connectivity and noise cancellation to deliver maximum performance per dollar where it matters most—the actual listening experience.

Compared to other vendors, Sennheiser's own lineup makes the value clear. The HD 599 sits comfortably above the entry-level HD 500 series models in refinement but well below the cost of the HD 600 series. For a wired, open-back experience, there are few competitors at this price point that offer this combination of proven driver technology, premium materials, and legendary comfort.

The most direct competitor is often the Sennheiser HD 560S. The 560S is a newer model with a more neutral, reference-focused sound profile. It's technically better for critical listening and has a detachable cable with a standard 3.5mm plug. However, it usually costs $50-$100 more. The trade-off? The HD 599 is the more relaxed, musical, and comfortable option, and it's significantly cheaper. If you're on a tight budget and want a fun, engaging listen, the 599 wins. If you need analytical precision and don't mind spending more, look at the 560S.

Then there's the wireless world. The Sony WH-1000XM6 and Sennheiser Momentum 4 are in a completely different category. They offer Bluetooth, world-class ANC, and all-day battery life. But they're closed-back, cost over twice as much, and their sound signature is more processed and bass-heavy. It's a choice between convenience and sonic purity. The Apple AirPods Max are even more expensive and locked into the Apple ecosystem. If you need headphones for commuting, travel, or the office, go wireless. If you want the best possible sound at your desk for the money, the wired HD 599 is the clear pick.

You should skip the HD 599 if your primary use is communication. The microphone scores in the 38th percentile, and real-world feedback confirms it's bad for calls, Zoom meetings, or gaming chat. The sound leakage also makes it a nuisance in shared spaces. If you need headphones for commuting, travel, or the gym, the lack of noise isolation and a wireless connection makes them a non-starter. All that outside noise will ruin your music, and the long cable is a hassle.

Instead, if you need a good all-rounder with a mic, look at a dedicated gaming headset or a wireless model like the Sennheiser Momentum 4. If you need isolation for travel, the Sony WH-1000XM6 is the benchmark. The HD 599 are specialists, and they're brilliant at what they do, but they fail completely at tasks outside their design.

For the dedicated home listener, the music enthusiast, or the budding audio hobbyist, the Sennheiser HD 599 Special Edition is an easy recommendation. They offer a gateway into high-quality audio that's engaging, comfortable, and built to last. Plug them into your computer's audio jack or a basic DAC/amp, and you'll hear details in your favorite tracks you never noticed before.

However, we can't recommend them for everyone. If you need a headset for video calls, gaming chat, or working in a shared space, look elsewhere—the mic is bad and the sound leakage is a dealbreaker. If you need headphones for the gym, commuting, or anywhere noisy, the lack of isolation and a wireless connection makes them impractical. For those uses, a good pair of closed-back wireless headphones is a better fit.
