Sennheiser HD 599 B508697

The Sennheiser HD 599 is a wired, open-back over-ear headphone that delivers exceptional comfort and a wide, natural soundstage for around $144 USD. It's ideal for music and gaming in quiet rooms, but the open design leaks sound and offers no noise isolation. Skip it if you need wireless, ANC, or a decent mic.

The HD 599 uses Sennheiser's 38mm dynamic drivers with a 106dB sensitivity rating, which means they get plenty loud without needing an amp. The 50 ohm impedance is a sweet spot: low enough for phones and controllers, high enough to avoid hiss from noisy laptop jacks. In our database, the sound quality lands at the 74th percentile, which is solid but not spectacular. The tuning is warm and slightly laid-back, with a midrange that flatters vocals and acoustic instruments. Bass is present but not punchy, and some owners say it can sound a bit muffled without EQ.

The soundstage is the real party trick here. Open-back headphones let sound move naturally around your ears, and the HD 599 does this better than most closed-back competitors at this price. For gaming, that means you can hear footsteps and environmental cues with real positional accuracy. For music, it means orchestral and live recordings feel spacious instead of cramped. The trade-off is isolation: there is effectively none. If you're in a quiet room, this is a feature. If you share a space, it's a problem.

Against the Soundcore Life Q20 and TOZO HT3, the HD 599 wins on soundstage, comfort, and build quality. The Q20 and HT3 are wireless with ANC and cost less, but they sound closed-in and their ear pads get hot after an hour. The Sennheiser is the one you'd pick for long listening sessions at a desk. The JBL Tune 670NC is another wireless ANC option that undercuts the Sennheiser on price, but again, it's a closed-back headphone with a bass-heavy tuning that won't appeal to anyone chasing a natural sound.

The Beyerdynamic Aventho 100 is a more interesting comparison. It's a premium on-ear headphone with a brighter, more detailed sound, but it costs more and the on-ear fit isn't for everyone. The Sony WH-1000XM4 is the elephant in the room: it's the best all-rounder if you need ANC and wireless, but it's nearly twice the price and its sound is more processed. The HD 599 is for people who want a wired, open-back experience without paying audiophile prices.

At $144 USD or 75-86 EUR/GBP, the HD 599 sits in a competitive spot. The Soundcore Life Q20 and TOZO HT3 both cost less and add wireless and ANC, but they can't touch the Sennheiser's soundstage or comfort. The Sony WH-1000XM4 costs significantly more and offers class-leading ANC, but it's a closed-back design with a very different sound signature. If you want pure wired audio quality and don't care about noise cancellation, the HD 599 delivers a lot for the money, especially if you catch it on sale. Just know that the "ANC" label in the spec sheet is misleading, this is a passive open-back headphone with no active noise cancellation at all.

The Sennheiser HD 599 is an open-back, over-ear headphone that sits in the budget audiophile bracket, usually landing around $144 USD, 83-86 EUR, or 75 GBP depending on where you shop. It's a wired headphone with a 3.5mm connection, a 38mm dynamic driver, and a 50 ohm impedance that's easy enough to drive from a phone or laptop. Sennheiser markets it as a special edition, but really it's the same HD 599 formula with a black finish and a slightly different cable setup.

People searching for this headphone usually want to know one thing: is it good for music and gaming without spending $300? The short answer is yes, mostly. The open-back design gives you a wide, natural soundstage that closed-back headphones in this price range just can't match. You'll hear instruments placed around you instead of inside your head, which makes it great for immersive games and acoustic music. But that open design also means sound leaks out and ambient noise comes in, so it's not a headphone for the office or a noisy commute.

Comfort is where the HD 599 really shines. The velour ear pads are soft, the clamp force is gentle, and at 100 grams these are among the lightest full-size headphones we've tracked. You can wear them for hours without your ears getting hot or sore. Just don't expect any wireless features, ANC, or a decent built-in mic, because this is a pure wired listening headphone.

Skip the HD 599 if you need any kind of noise isolation, whether that's blocking out a noisy office or not disturbing people next to you on a plane. The open-back design leaks sound in both directions, and there's no ANC despite what some listings claim. If you take a lot of calls, the mic is one of the worst we've seen in this category, so look at something like the Soundcore Life Q20 or Sony WH-1000XM4 instead. And if you want wireless freedom, this isn't the headphone for you, it's wired only with a 3.5mm jack.

Should you buy the Sennheiser HD 599? If you want a comfortable, open-back headphone for music, gaming, or piano practice in a quiet room, yes. The soundstage is genuinely impressive for the price, and the comfort is among the best we've seen in this category. The build quality sits at the 91st percentile, so these will last you years, and the removable cable means you can replace the most common point of failure.

But if you need noise isolation, wireless connectivity, or a usable microphone, look elsewhere. The mic quality is near the bottom of our database, and the open-back design means everyone around you will hear what you're listening to. This is a specialist headphone for a specific use case. If that use case matches yours, it's an easy recommendation.
