Well after falling in all the hype about combining a capable enough dsp dac amp with an open back headphone a person is propelled into a world of blissful surround sounds i decided to try this hands down once and for all. After about half an hour of burning the headphones in with some 24bit Flac songs i went ahead to test it. Played multiple songs and movies via the Walkman , X3 amp , Note 9 phone. First impressions: Build : The build quality is excellent, it's all plastic that seems like it is made to last and keep it light for comfort. The mechanism also feels reliable. So 5/5 Comfort: Very good , not fatigued after 1 hour , No unwarranted peaks in any frequencies. Its winters here in the north so it also doubled up as a scarf insulating my ears from the peircing cold. Sound isolation: Well what would one expect from an open back , it's terrible. But it is what it is. You have to be alone and in a quite environment to listen to these. Sound will leak both ways. Package contents: Well the box that comes with it is unimpressive, it is a waste like soft cardboard box which is labeled as "frustration free" packaging, it's all nonsense. If it was a good quality box one would use it to keep the headphones after use safely,and won't throw it away. No i will have to purchase a headphone case adding more to the environmental damage. You get two cables one being a 6mm and one 3.5mm with a 6mm to3.5mm converter plug. Sennheiser took good care in that area. Sound : Well i come from using the following in order of magnitude Most vintage models of Sony tape walkman headphones and earphones Mdr xb 60ex Mdr xb500 Mdr xb 90ex Mdr xb 75ap ( Skull rattler ) Mdr ex220 Asus rog headset Xba H3 ( My personal favorite in all areas ) Shure se 846 ( Skull breaker , My almost perfect set but gets beaten in High frequency department) As you can see there is only two over the ear headphones. Now i have always been disappointed by the music of over the head headphones due to lack of proper Isolation and driver limitations. Being my first open back This HD559 is no different to closed back in music department. Music coming out of it is unimpressive , you get almost no proper bass rumbles in the tracks that have them but maybe it's my fault. (more on that later). The soundstage although quite good does not impress you enough to warrant the sacrifice in sound isolation and lower frequencies. Sometimes some songs get tinny and empty, sometimes they come out good but never great. Apart from that i maybe wrong with my eqs and settings i will update after a week of listening. Movies : WTF This has blown all my in ear headphones far away , nothing comes close to the immersive theater like experience while pairing it with the X3 amp and switching on the xfi. You are instantly placed in a premium position of a proper dts tuned theater seat. All the action is all around you and dialog of the actors are clear and crisp even during intense explosions and gunfire. Things are properly imaged bodies dropping to the ground , bullets whirring past you thunders in the sky everything is represented perfectly. Imaging is more vertical than horizontal. Now the bass : While the music had no bass on it , on movies while on xfi turned on the bass reaches skull rattling levels without getting distorted or overlapping any other frequencies. It is unreal and brings a huge smile on your face and the only reason i did not return these back. The explosions shake you bullets fired seem real , thunders are near to being real. For movies this is the ultimate solution for me the END GAME so to say. Haven't tested it yet on games but have heard quite a praise for them in that regard. Conclusion: These mysterious headphones struggle to pump up the proper bass notes on music but will pummel your head in movies. Maybe i am doing something wrong on my amp but i have tried to bring it on the music by various ways. The world shattering bass is there waiting to be unleashed but with mysterious ways. The mids are perfect for both Male and females all the frequencies are present and quite powerful. The highs are a bit laid back and roll off at the highest levels quite quickly , whenever you will need them desperately they will bail out on you. But overall they are fine. Is it worth the money ?. For movies absolutely. 100% For music Maybe For games , haven't tested yet but i am confident they will excel in that department. Very good product. Highly satisfied.

I'd say the things people have said about this headphone's comfort level are NOT exaggerated or dramatized. This is the comfort king! Coming from earphones and IEMs, these things are a delight to wear and do not induce stress, which we normally feel after listening to music for long durations from IEMs, etc. I'm currently using this during the winter season so my ears don't get heated a lot even after an hour of usage. Will see how it performs in the summer season. I was curious to try an open-back headphone and I've been lurking on r/headphones for quite a while - taking opinions from people on whether it would be a solid upgrade over my chi-fi IEMs (CCA PLA13 planars). It was a risky endeavour so I did not want to go with a high-end model and this headphone fell perfectly in my budget range. I had read some negatives about this headphone when it comes to sound quality - that the sound appears muffled. Sadly, it is true that bass is overpowering and makes the sound muffled in certain situations. Now you may wonder why I still gave this a positive review. Well, let me tell you about the wonderful world of EQing headphones. EQ can completely transform the sound of your headphones. You can use EqualizerAPO + peace software combination to EQ the headphones (look up EQ profiles for HD 599SE on Google). I would suggest going with a Harman target profile as it sounds the best in general. One thing I would say is this headphone will not please users who listen to Rock/Grunge/Metal/Hip-Hop. in my opinion - IEMs perform better for those genres. I'm still discovering new things about this headphone and will keep updating this review if needed. Overall, I think this headphone is perfect for those who want to transition into the audiophile realm to experience high-fidelity music.

best sound quality and clarity for the price point. Pls note this is open back headphone so sound will defiantly leak and other's will be able to hear what your listening, but for personal use in a quite environment you can go for this without any second thought. For some it might feel flat sounding and less bass but that's what these headphones are made for :)

I bought these in Aug ( about 5 months back), so a long term review ig? tldr: I Have absolutely loved them since the day I received them and highly recommend for the open back option! PS: the open back hype is real guys, there is a huge difference Prior to buying them I had tried the: 1. Sony XM300 - great comfort and noise cancellation - hated the sound, found it too bassy 2. AKG MX50 - didn't find anything great about the sound, the build quality was amazing, the earcups didnt go over my ears, sorta stayed on top of them 3. Some IEMs - great for the price but very unreliable, usually not comfy So going into this my priority was straight - No compromise on sound, neutral sound (tho, if needed prefer bass over sparkle), good build quality, well known brand that has good warranty, price/performance ratio Note: I didn't care about the sound cancellation as I live in a fairly quite place For what I wanted, these are perfect in every sense. The sound signature is close enough to the HD6XX series while being almost half the price (in India atleast), the comfort is top notch even with specs, not too bassy while still being enjoyable in songs that need bass (a bit warm, great for long sessions), the tremble has never pierced my ears. Only downside I see is, i wish they were more portable.

I have owned several sennheiser headphones and IEMs, including open back headphones like HD238 and HD560s, i can clearly say that these HD599 SE are better than both of them in terms of mids performance. Listening to vocals on these is an absolute treat. Although these do fall behind HD560s in terms of overall soundstage and instrument separation, but they are still far more enjoyable than the reference grade HD560s because of their mids emphasised sound profile unlike the relatively neutral profile of the HD560s. HD599SE pros: - warm and smooth mids(vocals) - nice sound imaging - sennheiser natural timber - decent and clear treble - can be easily driven by my iphone12 - awesome comfort HD599SE cons: - bass rolls off a bit too much - lower mids region feels blending with bass at times - build quality could have been better Overall its a great value headphone with true sennheiser sound.

This headphone is great, its great for gaming, music and movies.. but the build quality leaves a lot to be desiered, the PU leather headband has peeled off entirely after 2 years, and there is no replacement headband. The sound is clear, crisp and no clipping even on very high volume (Fiio E10K), the soundstage is wide, and directional audio is top notch, great pair of cans for the price. recommended if you dont mind the flaking headband PU leather. However, I cannot recommend this for studio use, as there is too much sound leakage (due to being an open back) and the freq curve isnt flat. Very good highs and mids but the bass response isnt the best, im not saying the bass is bad, its still very good, but wont please the bass lovers.

1 Month Review - They sound really good whether in video games or music/movies, however the comfort is not there if you have a large head, due to plastic headband the headphones go back to their original shape even if you stretch them with a box for 15 hours, I can only wear them for 20 minutes straight before they start putting pressure on my jaw, for comparison Hyperx Cloud 3 will loosen up over time but these won't. Avoid if you have a large head but then again there aren't many alternatives and on papers Beyerdynamic are supposed to have 2x higher clamping force. These are called as the lightest headphones but I guess those who reviewed them aren't sensitive to high clamping force or have a small head. Verdict - Sound - 7/10 Comfort (clamping force) - 5/10 Comfort (earpad material) - 6/10 doesn't sweat but got compressed in few months Video games - 6/10 (elevated bass reduces the shrill sound of gun fire which is a plus point) Overall the clamping force makes long listening sessions unbearable ------------------------------- Novemeber 2025 - Clamping force is still the same, and they are extremely uncomfortable for long duration, I would rather get something with metal handband that can be stretched and tuned easily for long term.
