FiiOFH9 Headphones Earphone Wired High Resolution Over-The-Ear 1DD+6BA Detachable Cable Deep Bass Comes with 2.5/3.5/4.4mm Swappable Plugs for Smartphone/PC/Players/Home Audio(Titanium)

I have been in search of the prefect IEM for a long time now, even giving up on the format for a while. My first real foray into the IEM world was with the ATH-CKW1000ANV and they were where I found the sound I was looking for but it had numerous issues and led to the JVC HA-FXZ200 and these were exceptional but required using the tipple flange tips to get a great seal and the bass that would dig into the basement. After looking at a ton of reviews I made a major investment into the FIIO fh7... and was thoroughly disappointed. While a technically accurate headphone it was not one I got much enjoyment out of as it became sibilant at moderate volumes. In short they were not the headphone for me despite being the flagship at the time. Looking back I should have picked up the FH5 as it seems to have the musicality I am looking for. So buyers remorse is kicking in hard but FIIO throughs me a bone and announces that there is yet a higher end model coming and I do my best *shut up and take my money* and picked these up on launch day.... The presentation is lovely and everything feels like money well spent. The interchangeable 1/8" 2.2mm and 4.4mm are a boon and must be praised. And speaking on the cable I give it full marks it looks lovely and feels good in the hand.On to sound. These are it. This is what music should sound like to me when I put these on with no eq or trickery. They rock and crank up without any hint of sharpness or overdrive. One of my favorite test tracks is Finks live troubles what you are in. In this you get an acoustic performance that you can hear the strings plucked while the acoustic bass guitar vibrates your eardrums but never gets muddled and the box drum is clear. All summed it is the best experience I have had to date and I set the bar high here with the headphone corner defended by the meze elites and the speaker corner defended by my legacy signatures. The FIIO's pack all that fighting power in a manageable price tag.Ear bliss with no down sides... would be a six out of five if I could but five or five stars will suffice.

Bought these to compliment my Beyerdynamic over ears, mainly for their portability and high marks in reviews. Came as advertised with a nice travel box, cleaning tool, insane amount/types of tips and filters to help dial in the tone you want. Everything is over engineered. From the IEM to the cable and accessories, they pulled no punches in fit or finish. These are not cheap, and you get what you pay for. While I know there is a lot of competition at the price, build quality and accessories alone are hard to beat with these. Sound is personal, and to me these are great. The clarity and space are tough to find elsewhere. Although highly tunable, if you're a basshead or like a lot of treble, you may look elsewhere for something more specific. Well balanced, clear, 3D, articulate, adaptable, and easy listening for long periods are how I describe them. The semi open back let's you prevent fatigue, and listen at lower volumes without missing anything...yet nobody around you can really hear them...huge win and probably healthier for your ears. While easy to drive, they need an amp to get most out of. Noise isolation is so-so, as expected with semi open designs. The tip kit comes with double flange tips, but have not tried them. Currently running the balanced filters with vocal tips and couldn't be happier.

EDIT: September 2023It took me a while to get here. By finally getting to know the house sound of FiiO - i.e., warm midbass with moderate treble - ended up getting the FH9 once again in late 2022. And what a comeback.Stock eartips are fine but there is a whole world out there. As of today, my favorite eartips with the FH9 are the AZLA SednaEarfit, AZLA MAX and the Final Audio Type E.I liked this earphone so much that ended up getting the other one to be used wirelessly.If you're into measurements, look at the crinacle graph with B&K 5128. It is impeccably neutral with a bass boost. Endgame. Period.-----Original review from April 12, 2022Original title: "Ended up not replacing my SE846"The only aspect that the SE846 beats the FH9 is related to comfort, IMHO. The FH9 is bulky and was too big to my average sized ears. A couple of long sessions were fatiguing. Other than that, the FH9 is simply better in every other aspect when compared to the SE846. The very well balanced tuning, build quality and accessories. Wonderful job from FiiO here.I played a lot with the different tips and tuning filters. I have read somewhere that the FH9 has a V-shape tuning. Not to my ears. It has a somewhat punchy bass, good mids and a very good lower treble. Even with the bass filter and tips, this may not be enough for the bass heads out there. I wish the FH9 would be even punchier in this regard.I really wanted to keep this IEM. However, I still own the SE846 and did not want to keep a redundant "SE846 on steroids" around. But the real deal breaker for me was the fit. Other than that, the FH9 is a great all-rounder and is very forgiving on poorly recorded tracks. I would say it has a neutral signature with elevated bass.EDM is really fun to listen with the FH9 so is the SE846. I just wish the FH9 existed before I purchased my little Shures in late 2020.
