For the 130 euros I spent, these headphones changed my life. They have what is called a "soundstage", meaning how well the instruments are positioned around your ears. Right, left, center, and everything in between. The instruments are very nicely separated from each other. The bass is not very strong, but it is incredibly honest and clear. This can also be said for the headphones as a whole. All the frequencies are clean and honest. It's very easy to give them enough power, from computers and mobile phones. Compared to any Bluetooth headphones or earbuds at this price, they are infinitely better. Additionally, they are very comfortable. After two minutes you forget they are on your head. Just don't expect sound isolation. Whatever you hear, those around you hear as well.

Amazing headphones! Out of the box, they are bassier than I would like, but after applying Oratory's settings to a free EQ, the true crystal-clear sound of the headphones is revealed.

They are super lightweight, you forget you're wearing them. Their ear pads are very soft and their build, although mostly plastic, is of very good quality and they seem to be extremely durable.

I was afraid that because they are open back they would sound very loud in the room, but in the end, there is no such problem. The sound that bleeds out is as loud (and even less so when you're wearing them) as closed back headphones sound when you're not wearing them.

Very good sound for its price, of course with Dacamp it shows all its virtues. There are many reviews from people who have much more knowledge than I do, so read them and don't forget that perception and taste in sound (as in many other things) are subjective.

Like classic and well-known Sennheiser, extreme sound quality, very comfortable, they don't strain the head at all. As a usual user of headphones in the range of €30-40, it is a big surprise and a significant step up in listening quality.

The best thing about them is the sound, which is amazing and clear. The bass is satisfactory for open back headphones, I have no complaints. They are lightweight yet sturdy, as they have fallen down 3-4 times and still work fine. They are comfortable on the head. The headphones come with a cable of about 2.5-3 meters. One end is 3.5mm for the headphones, and the other end is 6.3mm for connecting to a sound card. It also includes a smaller 3.5mm to 3.5mm cable and an adapter from the larger 6.3mm plug to 3.5mm. Now, regarding the cushions, they are very comfortable and easy to remove and wash.

I have had this product for about three months now, and I am impressed with both the quality of construction and the sound itself, as it is clear and "open", which is greatly helped by the fact that it is open back. It works very well with a simple 3.5mm jack on a computer or mobile phone, but with a sound card, the capabilities of the headphones are much greater. From my own experience, I would highly recommend it, as it not only has better sound but also better construction compared to headphones of this category such as the Audio Technica ATH-M50x Wired Over Ear Studio, although not as good as the DT 770pro. The only downside, or rather a good thing depending on the use of the product, is that it is open back, which means that the sound will be heard outside of your ear.

I received them on 22/07/21, so I have had them for almost 1.5 years at the time of writing this review, and I really love them. Incredibly comfortable open-back headphones, very enjoyable sound but at the same time BALANCED, you can truly hear all frequencies well. I am clumsy with them, they have fallen several times and even though they are made of plastic, they haven't suffered any damage. They have a detachable cable that "locks" into the headphones, so if something happens you can simply replace it. They are so lightweight that you don't even realize you're wearing them. They have low Ohm, so they don't require a good sound card, they produce good sound on all devices. The only downside for me is that the ear pads get dirty easily due to their material, but it's one of the reasons why they are so comfortable, so I can't complain. 10/10, I highly recommend them.

My first open back headphones.
I admit that having been accustomed to other types of headphones (closed back, Bluetooth, etc.), I was initially not satisfied.

As a beginner in the field of headphones and good sound in general, I had the feeling that the music was weak and lacking volume.
I use them with an ifi zen can amplifier.

After a month of use, everything changed.
I think that the way I listen has changed.

Detail, comfort, clarity, and for the first time, I can distinguish the instruments.

For the money I spent, what I get back is disproportionately good.

I highly recommend them, especially to entry-level listeners like myself.

At 125 euros, it's the best in terms of comfort and sound quality 5/5.
It is open back, so don't expect sound isolation.

After many months and really a lot of searching, I ended up with the HD 599, the difference with the steelseries siberia which they replaced is really HUGE. Clear sound, I would say crystal clear, without unnecessary bass which is the best for the use I want them for. Overall, I was looking for headphones for fps gaming (warzone) that would give you that extra something in terms of awareness. Now I hear everyone and everything. I was disappointed because I wanted the classic gaming headset with a microphone, but with 50 euros I got an extra microphone with a 'crane'. I couldn't have made a better choice. And guys, let's not fool ourselves, at 119 euros in terms of sound quality and not RGB and stories, it's the best you can get, completely comfortable and lightweight after many hours of use. From me, 5 out of 5.

Generally, I am unfamiliar with sound and did not want to get involved with an amp. I wanted something with low ohms to perform well on mobile laptops and the PS5. I don't know if I could have made a better choice. The sound in movies and gaming is incredibly detailed, especially where there is good sound design, the experience is something unprecedented. Also, their open-back design greatly helps to feel the space. For music, some are fantastic with very realistic bass and fantastic results in vocals, while others are just good. A very good choice and I think the price is good at 150.

Update one year later+ (07/07/2022): it is perhaps the best purchase I have made, incredibly comfortable headphones, amazing in all aspects, and you can wear them for hours without getting tired at all.

There are no other headphones at this price range that separate all frequencies so well, have such detail and a huge, truly huge soundstage. They are truly incredible, I fell in love with the sound from the first moment I heard them and over time it became even better. They make you want to turn up the volume to the maximum! I don't know why everyone here says as a negative that they don't have sound isolation, come on guys, they are open back headphones... I would recommend to anyone who buys them to also invest in an entry level amp

Classic Sennheiser headphones, you turn the sound all the way up and you don't hear the slightest distortion. Anyone who has used other Sennheiser headphones, even the cheaper ones, knows more or less what to expect. The sound is sweet without being tiring at all, the lows, mids, and highs are well separated, unlike the 598s, the 599s have bass, don't expect it to be like the Fidelio X2, and the sound gets even better over time. Another point where Sennheiser excels is how lightweight they are, the Fidelio X2s tired me out a lot, but with these it's like you're not wearing anything. I see many people consider it a negative that they don't isolate external noise... guys, they're open-back headphones. For me, the only negative is the cables that Sennheiser provides, they're very plastic, the connection to the headphones is a 2.5mm jack and it has a notch to lock it. In other words, if you want to buy another cable, you have to get it from Sennheiser for 20 euros.
