[Sealed] Got this replace an old one that broke a few days ago. This one look more endurable and much more comfortable to wear.

[2] My entry into the world of audiophile equipment. Honestly, I don't have the experience at this point to judge these excellent cans against anything above this tier, but I'm already looking at getting another set of headphones (an upgrade) very soon. That's not to say I'm in any way unsatisfied with my experience with the Fidelio X2HR's. The opposite! I'm feeling so drawn now to the pursuit of better, more detailed, or different equipment because of the whole new world of audio I've discovered while the X2s peacefully melt me into complete aural bliss.
It's no overstatement. I'm prone to constant multitasking, so for the past few years, my music experiences have been yoked to some form or other of work. I don't think I realized the creeping depreciation of my love and respect for good music over the years. I'm saddened now to think I let myself get to that point. But, alas, the Fidelios have redeemed me of my sin of omission and now my feet are firmly planted back on the straight and narrow, so to speak. I find myself for the first time in so many years losing track of time rediscovering (or indeed discovering) sonically superior scores on this sublime set.
In all seriousness, I recently got into some higher resolution music and tried out various streaming services (Amazon Music HD was my favorite by far). There was noticeable difference on even my regular headphones and AirPods Pro. Putting these bad boys on and playing anything RedBook and above is, for me, the yet barely initiated, the best way I've ever experienced music. You feel as though you are on stage with the band. The separation is great (of course there's better), and they are not fatiguing. You can crank the volume up and up and it just sounds better and better. In sum, I want to speak directly to those thinking about getting into the audiophile lifestyle: THESE ARE THE ONES TO START WITH. I can't imagine one not being extremely satisfied with the X2HR's, so just get them now!

[25 to 150 Hz] For some reason, I brought a TRRS male to TRS male cable with mic (primary used for old Sennheiser HD485), and I saw this headphones in BH store, and tried it with the cable I brought, and I was surprised how good the sound even with a smartphone (I tested with few YouTube music videos).
After I tried with few YouTube music videos, the store started to close, and OK, go for it and I was the last customer left with this HUGE headphones.
I put it on when riding train. Sensitivity is actually enough for both music and phone call, but due to the size, it's recommended to listen it at home or office (this headphones is pretty comfortable for extended phone talking with boom mic).
After I got in my friend's home, I spent a lot of time to listen to some local music made from CD in FLAC format, and I am blown away how good the sound is (it has a lot of bass but it's not muddy at all) and I like it more than Sennheiser HD598 and ESP500.
I planned to buy Sennheiser HD600, but I worry sensitivity is too low for smartphone. The phone is capable with 32bit/192kHz with PowerAmp.
Open Air design can let me hear anything around me.
Get additional cable with TRRS male to TRS male with mic (or boom mic) and have fun with your smartphone or tablet.

[1%] open-back headphones provide a more natural sounding experience with a wide soundstage. The price paid for this is sound leakage to the outside and - often - weak response in the low frequency region. However, Philips has managed to achieve a warm and rich sound with powerful bass already in the Fidelio X1. In next flagship, these qualities are not only preserved, but also improved. The improvement in the sound of the Fidelio X2 versus the X1 is obvious. Headphones are noticeably better at handling voices, brass instruments, cymbals, and subtle nuances in the high frequency range. The bass is booming and full-bodied, but they have become more balanced, better controlled. The sound signature of the Fidelio X2 and X1 is similar, but the new flagship sounds more mature. The response across the entire frequency range is smoother, which will certainly appeal to audiophiles and personal audio enthusiasts. Music is played more pleasantly and naturally, but still fun, without monitor dryness. In addition, headphones are well suited not only for listening to music - surround sound and powerful bass help to immerse yourself in the atmosphere of movies or games, explosions and various effects sound great

[2] The Philips Fidelio X2HR Headphones I purchased at a savings of $150.00 off the regular price are excellent. I use them to monitor recordings I make of my LPs to a digital format on my desktop. The sound is clear and true to the original recording and they fit very comfortably on my head. I will also use them to simply listen to my LPs in quiet comfort.

[Black] This Philips Fidelio X2HR choice was my first open-backed headphones after always using closed-backed. It was a great choice. The sound is much better than I was used to and the comfort level on the ears and head is also much more comfortable. I am not an audiophile like some of the other reviewers, yet I am very pleased with my choice. I highly recommend these headphones.

[Floorstanding ] I wouldn't pay full retail for these headphones, but at the current sale price, it's a great set of headphones if an open back design will work for you. Keep this in mind - professional studio recording headphones have to be a closed back design, for multiple obvious reasons. It's more difficult to get neutral balanced sound from the drivers with closed backs. So thus you get the whole headphone scene for audio production tasks. You can't use these Philips headphones for any of that, but for normal consumer enjoyment of music, if nobody is bothered by the sound coming out the back of the phones, these sound absolutely fantastic. Beautiful open, clear, three dimensional soundstage that presents any recording at its best.

[25 to 150 Hz] I also own an hd6xx and wanted to add an x2hr to my collection and I'm glad I did! These are detailed phones with a wide soundstage, with good response across the entire frequency spectrum. Maybe not quite as refined as the hd6xx, but gives a different sound impression. Great with classical too!

[Sealed] are they flat? no.
these aren't reference cans, they're not lightweight and they're not flashy.

but they are well built, easy to drive, look really good, and sound really, really good.
bit of a "V", (which is nice and fun) but still detailed with a great soundstage.

I love them.
better than the X1s, the X2(non HR)a and miles better than the x3s

I can't think of a more enjoyable set in the price range.

[Active] This works very well in concert with the app that tells you a lot of additional details about how much of the battery you have any other aspects the only issue I had with it and I had to return and get that you copy of this. Is that the battery did not reflect correctly on the app make sure you have the most recent version of the app so it reads the battery correctly. It's a 36 hour battery which is fantastic. Janet has many technological improvements. The entire package and leather is top-notch quality, and the sound of the headphones is well balanced, and pleasant rate value when it says &149 on sale. My daughter also built one well I bought it for her and she's very happy.
