Perhaps the most interesting thing about the Fidelio X2’s is the fact that they are open backed headphones that really excel in the bass department. Closed back vs. Open back headphones. Many people couldn’t believe how good they sounded because generally open headphones are kind of lean in bass and it isn’t as prominent.
It’s important to remember that the X2’s aren’t meant to sound neutral. They have a fun/warm sound signature, with a great soundstage and instrument separation. I would call them bass head cans without the bloat that you may get with other models. Think of the sound overall as mellow and airy.
Good build quality. Feels durable and the headphones have a lot of metal to them.
Low clamp pressure and very comfortable.
Great bass response, but sometimes can be overpowering and too much.
EDM/Drum and bass, although sometimes they can get kind of loud and uncomfortable sounding.
Thoughts from Stu’s notepad
Beware of defective and counterfeit pairs of the Fidelio X2 that were manufactured by Gibson after Philips sold the consumer electronics dept. to them. A big issue is glue on the ear pads when they are marketed as being removable. There have also been reports of other cosmetic issues with the metal trim pieces around the ear-cups being glued incorrectly.
The mid-range is a bit recessed due to the strong bass presence.
Included is a 1/4″ adapter with 3m cable and 3.5mm termination. Pretty standard.
The stock ear pads will collect a lot of lint and will have to be cleaned often.
If you’re fortunate enough to get the ones that don’t have glued on ear pads, they can be replaced with the Brainwavz HM5 pads relatively easily.
They are very forgiving of your source so you won’t have to worry too much about them being too analytical and revealing of poor quality files. This could be a good or bad thing depending on your preference. I tend to gravitate towards honest and neutral, but I still love a fun sound and don’t always like to be super critical of my music.
These aren’t too portable, as they are big and of course open backed. They will leak sound so you’re best scenario is to use them in studio.
The self adjusting head hammock is a welcome change from your traditional head band and works nicely.
These tend to do well with bigger heads, and if you are a Conehead, even better! 😛 If you’re a dainty female, they are likely to take up half your face. Lol.
The chord here is also not proprietary so you can replace it with any external cable of your choosing.
Buy them if you’re willing to take a gamble on which version you will receive. A lot of folks tried a few times sending them back and were finally able to get the correct model without the glued on ear-pads.
Similarities & Differences
Both have 50mm drivers and according to many, they both use the SAME driver. Take this with a grain of salt though.
Both headphones have a tendency of moving around on your dome piece a little if you move around a lot. I noticed this with the 9500. They are comfortable, but will move if you make a sudden movement.
Both have replaceable chords.
Both have around the same impedance. 32 Ohm for the 9500 vs. the 30 Ohm of the X2.
Around the same sensitivity. 101dB for the 9500 vs. 100dB for the X2.
The wiring on the X2’s is braided while the 9500’s have a traditional straight cable.
The 9500’s are fairly light while the X2’s are much heavier.
The 9500’s have a balanced, neutral signature while the X2’s seem to be more bass oriented. The low end tends to bleed into the mid-range.
The 9500’s use a peculiar cloth that feels a bit odd, while the X2’s use a velour/memory foam type of material. The cloth of the 9500 isn’t unpleasant, it’s just different.
The 9500’s tend to be sharper in the treble range, leading to more sibilance.
The 9500’s have a shallower ear-cup and your ears will probably touch the drivers inside. The X2’s cups are a little deeper.
The X2’s soundstage is more noticeable and more open sounding.
The X2’s will perform better for movies/gaming while the 9500’s excel more in stuff like podcasts and youtube videos.
The mid-range on the X2’s is better than the 9500’s.
You may become fatigued quicker with the 9500’s, meaning certain types of voices will wear your ears out faster.
The X2’s utilize that hammock head band self adjusting mechanism while the 9500’s go for a more traditional fit.
While the X2’s are the better headphone overall, is the extra cost justified? Some say it’s not, and that the differences are minimal enough to where you can purchase the 9500’s and feel okay with it. I happen to really enjoy mine, and couldn’t believe I was getting this type of sound for less than $100. Interested in learning more about them? Check out my review!
