Sennheiser HD 599 B508697

The Sennheiser HD 599 SE is a wired open-back headphone that nails comfort and soundstage at a reasonable price. It's a great pick for home listening and gaming, with balanced sound and a lightweight 250g build. Just don't expect bass-heavy tuning, noise isolation, or a decent mic.

The HD 599 SE uses a 38mm dynamic driver with a frequency response of 12Hz to 38.5kHz. That's wider than most headphones in this price range, though the top end is more about headroom than anything you'll actually hear. What matters is how it sounds, and the answer is balanced. The mids are clear and present, treble is smooth without getting sibilant, and bass is controlled but not thumpy. If you're coming from consumer-tuned headphones like Sony's XB series, the bass will feel light. That's intentional. Sennheiser tuned these for accuracy, not rumble.

Sound quality lands at the 71st percentile in our database, which is solid but not chart-topping. The real star is the soundstage. Open-back designs let sound breathe, and the HD 599 SE delivers that spacious, out-of-your-head presentation that makes closed-backs feel claustrophobic by comparison. For gaming, this translates to better positional awareness. Footsteps in shooters, environmental cues in RPGs, it all feels more natural. The 106dB SPL sensitivity means these get loud without much power, so a phone or controller can drive them adequately. A dedicated amp will tighten things up, but it's not a requirement.

Against the Sony ULT Wear WH-ULT900N, the comparison is almost apples to oranges. The Sony is wireless with ANC and heavy bass emphasis, while the HD 599 SE is wired, open-back, and tuned for accuracy. If you need noise cancellation and portability, the Sony wins outright. If you want a natural listening experience at a desk, the Sennheiser is the better tool. The QCY H3 ANC and JBL Live 780NC are both budget wireless options with ANC, and they'll beat the HD 599 SE on convenience and isolation, but neither touches it on soundstage or long-term comfort.

The more direct competitor is the Philips X2HR, which owners frequently mention when discussing the HD 599 SE. The X2HR has more bass presence and a more premium-feeling build with metal components, but it's also heavier and typically pricier. The Sennheiser counters with lighter weight, better long-session comfort, and a more neutral tuning. For gaming specifically, the HD 599 SE's imaging is a real advantage. The Anker Soundcore Space D1402 is a budget closed-back that can't really compete on sound quality, but it's also a fraction of the price and offers ANC. Different tools for different jobs.

Value is where the HD 599 SE gets interesting. At full US retail around $240, it's a harder sell when the Philips X2HR and various Beyerdynamic options hover nearby. But these go on sale constantly, and owners consistently say the real magic happens when you catch them discounted. European pricing is much friendlier, with EUR 81-86 and GBP 68 making these an absolute steal. Canadian buyers should watch for the CAD 212 end of the spread rather than paying CAD 330. The included two cables, one 3-meter with a 6.3mm jack and one 1.2-meter with 3.5mm, add practical value. For the sound quality and comfort on offer, especially at sale prices, these punch well above their weight.

The Sennheiser HD 599 SE sits in that sweet spot where open-back headphones stop being a niche audiophile flex and start making sense for regular people. It's a wired, over-ear, open-back pair that usually lands around $240 USD in the US, though European buyers can snag it for roughly 81-86 EUR and UK folks around 68 GBP. Canadian pricing is all over the place, from CAD 212 to CAD 330 depending on the vendor, so shopping around matters more than usual here. The HD 599 SE is the special edition of Sennheiser's HD 500 series flagship, and it's aimed at anyone who wants a taste of high-end sound without selling a kidney.

People searching for these usually want to know three things: is the HD 599 SE good for gaming, does it need an amp, and how does it compare to closed-back options. The short answers: yes, it's genuinely great for gaming thanks to the wide soundstage and precise imaging. No, the 50 ohm impedance and 106dB sensitivity mean your phone or laptop can drive it fine, though a cheap dongle DAC helps. And compared to closed-backs, you trade isolation for a much more natural, spacious presentation. That's the whole point of open-back design.

Build quality sits at the 91st percentile in our database, which is impressive for a mostly plastic headphone. The velour pads are plush, the weight is a feathery 250g, and the detachable cable system means you won't toss the whole thing when a cable dies. The proprietary 2.5mm connector on the earcup side is a minor annoyance, but more on that later.

Skip the HD 599 SE if you need any kind of noise isolation. Commuters, office workers, and anyone sharing a room with other people will find the sound leakage a dealbreaker. Bassheads should also look elsewhere, the Philips X2HR or Sony ULT Wear deliver more low-end punch. And if you take a lot of calls or do voice chat without a separate mic, the weak mic performance at the 15th percentile makes these a poor choice. For those use cases, a closed-back wireless pair with ANC like the JBL Live 780NC or Sony ULT Wear makes way more sense.

Should you buy the Sennheiser HD 599 SE? If you're looking for your first open-back headphone and you mostly listen at home, yes. It's comfortable enough for all-day wear, sounds balanced and natural, and the soundstage makes both music and games more immersive. The 4.6 out of 5 rating across 35 reviews backs that up, with owners consistently praising comfort and sound quality. The proprietary 2.5mm connector is annoying, and the bass won't satisfy bassheads, but those are trade-offs, not dealbreakers.

If you need something for commuting, office use, or calls, look elsewhere. The open-back design leaks sound like a sieve, and the mic performance is genuinely weak. But for a dedicated home listening setup, especially if you can catch a sale, the HD 599 SE delivers a lot of what makes high-end audio special without the high-end price tag.
