Summary: The X1 does many things quite well and blends them together to produce a consistently pleasurable listening experience.
Bass is excellent for an open dynamic headphone, but not excessive, and blends well.
Overall tone is a bit warm, but not overpoweringly so (less so than an HD650). Detail is good (not excellent), but these are not analytical headphones.
Pros: Euphonic fun headphone that works well for most genres of music and represents very good value for the price
Cons: Earpads not user replaceable, need to swap stock cable
Summary: What can I say about this headphone that hasn't been said? I just know that all the stupid things about it - the cable with stupid resistance, the non-replaceable pads, the strange headband, the fact that they probably aren't making it any more - all of those things just fade away when you put them on.
They're accurate. Sure, not totally accurate - not like my K550s or HD598s - but an accurate that adds enough excitement to make good music fun.
I no longer have this can and am posting a copy of a reply to a thread. I figured after writing it it would be somewhat useful since there is no rating here and people like me come here a lot to see direct reviews of an item before purchasing it. This headphone is a weird one to nail and should have some warnings before purchasing it.
However I think my memory of this can is trustworthy.
Pros: detail, air, bass, neutrality (besides bass), comfort, looks, easy to drive, soundstage, lack of sibilance
Summary: I highly recommend these for anyone that wants bass and soundstage. They deliver both flawlessly.
Yes, there are more accurate headphones, and more thumpy headphones, but this strikes the perfect middle ground.
If any weakness exists, it is in vocal music, the likes of Norah Jones.
The bass is there, never gets in the way.
In short, these are unique.
Pros: Comfortable for big ears. Exciting sound, great soundstage, clean bass. Easy to drive.
Cons: Non-user replaceable pads. Leaky sound for some.
Summary: These headphones are a huge step up from anything I've ever heard before.
The only other well known headphones I've listened to extensively are the Sennheiser HD 202 and the Logitech UE6000. Compared to these headphones, the sound quality of the X1 is better in every way.
In my opinion the Fidelio X1 has a truly fantastic bass and treble response.
Pros: Fantastic bass, treble and soundstage. Quite comfortable. Easy to drive.
Cons: Vocals could be more prominent. A bit bulky. Not the lightest headphone.
Summary: If you love acoustic unplugged smooth jazz, blues rock and classical music, go with this beauty from Philips. Fidelio X1 is perfect. So comfortable to wear. When I hear John Mayer strumming his guitars, I get goose pimples over and over again.
The cable is unusually long. However, the cable is detachable and a shorter cable be used. This makes it convenient for outdoor use.
Pros: Detailed, clear differentiation of classy acoustic music like those of John Meyer, no overpowering bass to mask the details, cable is removable.
Cons: Need an amplifier to power up the headphones. Ipod or iphone is too weak for them.
Summary: These are literally the best headphones I have ever put on my ears. After a five minute settling period, I can't even feel them on my head. They're very lightweight and both the ear cup and headband padding is absolutely top notch. The tension literally could not be more perfect and the center of mass is tight to my head, keeping them from sliding or shifting when I turn.
Pros: Soundstage is spectacular, feeling is flawless, audio is awe-inspiring
Summary: I'm slowly going to add more and more to the review! The reason I make this short review is that the few info it has might be meaningfull to someone!
Still burning in, somehow and without noticing it first the voices became very much in your face. Still checking whether gear makes a difference. They also started to sound less closed later on.
Probably not a good match with e10.
These are NOT an outdoor headphone.
Pros: Nice sound, sound good out of everything!, Good beginners headphone, Comfort, Design, very easy to eq
Cons: Audiojack seems fragile, Voices are too upfront/close by/
Summary: Perfect headphones Pro's Sound Looks Build Comfort I prefer them to Grado SR60i, 80i, 125i and 225i. I still have some 125i and these blow them away, the comfort of wearing the two is chalk and cheese, the grados feel awaful to wear compare to the philips.
Summary: Outstanding headphones, it has everything and bass... oh the bass for a open can this is remarkable stuff. I was disappointed at first due to my Soundblaster silly EAX effects and stuff, so I reset everything and also bought a Fisual S-Flex Mini 3m 3.5mm Jack to 3.5mm Jack Cable, as suggested by the reviewer on here and headfi youtube guy Tyle. I use Foobar 2000 and WASAPI output with a couple of DSP effects mainly DOLPY HPH, noise sharpening and crossfeed.
