Honestly I wonder why these cans aren't more recommended all over the place, these are ridiculously good even at 180€, far better than the 598CS and the classic 598. Even in gaming these are better than the 598 because the soundstage is more precise and more sperical compared to the regular 598 and their tunnel-like soundstage (at least that's what I remember from before I sold the old 598). I'm going to add a few more details even though nobody seems to care about these cans for some reason.

Assetto Corsa Competitizione has amazing sound design, and you can really appreciate it with these headphones, especially using the in-car view. It feels like you’re in the car, and you can accurately hear the curbs, other cars, and even how your tires are doing based on the sound alone. Grenades exploding in the distance, footsteps, and gunshots around you in Counter-Strike are goosebump-inducing with how wide the sound stage sounds on these headphones. Imaging Don't give up on your HD600 for gaming just yet. A headphone doesn't need to be 'designed for gaming'. If you read such a thing that is pretty much marketing.Disclaimer: The Sennheiser HD599 was sent to us on loan by Sennheiser’s PR agency. It will already have been returned when this review is published. Even when listening to discs on which bass was not skewed (Paul Simon “Stranger To Stranger”, Radiohead “A Moon Shaped Pool”), one does not feel their exaggeration. But that’s not all – good control of this range is complemented by clear, transparent, and saturated sound colors. When needed, the low components can surprise you with real momentum and freedom, but even then each hit seems precisely programmed. The specific “violent storm” known from the HD 589 has given way to “accuracy of mathematical machine operations”, which turned out to be good for the whole presentation. It’s always worth waiting for the annual Berlin IFA for just one reason – the first official presentations have devices that will not be available until after some time. It resembles a fashion situation – the latest trends appear before the actual season, which allows you to organize the wardrobe and prepare for the arrival of the “new”. IFA is, therefore, a kind of compass of the latest trends and it is not surprising that it attracts the most important manufacturers from the industry, including, of course, the local, i.e. German. Marketing people always find interesting statements, don’t they? I do see what they mean though and for a whole lot of people who never experienced decent sound this most likely will be the case. The keywords that come in to mind when listening to the HD599 are smooth, engaging and musical and all that in a very possible way. The HD599 simply sounds smooth and is easy to listen to and it to a lot of ears will sound natural with a lovely warmness. Sennheiser achieved to make the HD599 smooth and detailed at the same time and because of that it will please both the new listener as well as the more experienced one. The H599 is a headphone you can perfectly use for watching movies and for listening to music to, it’s a great all-rounder. The mids are well balanced on the HD 599 SE, but similarly to the HE400se, they tend to drop off at around the 1.2-2kHz range, though not nearly as much. I suppose this is done on purpose to reduce the “shouty” frequencies that tend to make the listening experience a bit harsher.

When you look at the HD599’s press material you immediately notice this headphone is branded as a top of the line “do-it-all” headphone for watching movies and for listening to music and basically anything that can be done with a headphone. The HD6XX and all the higher end models are marketed as pure audiophile headphones for music listening. Should you fork out the bills for this one? If you’ve been searching for an impressive dynamic sound with plenty of highs and plenty of lows – and the HD 598 just didn’t cut it for you – I’m willing to bet you’ll love these cans. To my own ears, they sound just a tad cleaner than the 598, but don’t tell the fanboys I said that.After having launched the HD800S and the new HE-1 headphone, Sennheiser decided it was time to update the existing 5XX product line, of which the iconic HD598 is part of. The new HD598 is called the HD599 and that means it’s closer to the HD600, in more ways than you can think. The best gaming headphones IMO, are the ones that are best at reproducing binaural soundfields accurately. Newer game engines are becoming more realistic with spatial audio and headphones such as the 600 can actually create a more realistic sounding reproduction of a binaural sound field over the 598. It's the reason both HD700 and HD800 are good for gaming as well.
