Drop x JVC HA FDX1 Impressions
Thanks to
Super* Review for loaning the FDX1 and a couple other IEMs! I have a post
here on Reddit going through a bunch of the other IEMs he lent me.
Right, before I forget - the nozzles. There are three nozzles included (green, blue, and stock) each with varying degrees of dampening. The green...yeah, I'd just stay away. It completely neuters the FDX1's dynamics. I don't really hear much distinction between the stock nozzle and the blue nozzle when it comes to dynamic ability, but the stock nozzle also brings up the upper-midrange a good deal more than I'd like. Too bright, too shouty, so no thanks. All impressions are with the blue nozzle.
The overall tonality of the FDX1 is neutral to my ears. Pretty unremarkable, if not well-done. On the other hand, the intangibles are interesting, particularly in the bass. Transient attack is just...clean. I don't have another way of putting it. But decay does leave something to be desired; it's caught somewhere between a DD and BA. Bass texture and transient density are subsequently lost; dynamic slam has a sort of wet, puckered quality to it on deep drops. Besides throwing me off, it doesn't hit my preferences very closely, and I can't say I'm a fan. Midrange-wise, the FDX1 peaks a bit later at around 4kHz for its ear compensation. My personal preferences lie at around 2-2.5kHz, but it seems fine to me if not somewhat thin, which is done no favors by the quicker decay. The treble of the FDX1 is characterized by mostly lower-to-mid-treble impact. Even then, I don't think it has very much, and it reminds me of my Moondrop KXXS. Probably the biggest "dealbreaker" if there is one, as it sounds a bit muted contrasted to the upper-midrange. I don't really mind, though, and it's not offensive at all. It stands that these are all minor nitpicks, and the FDX1 gets a whole lot more right than it gets wrong.
Technicality-wise, the FDX1 is darn solid. It's not hitting Dunu Luna levels for transient speed, of course, but it's quite resolving; a good step up over the Etymotic ER2XR and Moondrop KXXS. Image incision is within the realm of average; positional cues and center-image diffusal slightly ahead. Macrodynamics are generally skewed downwards, but with enough contrast to be satisfactory. I don't think there's any real standout here, but the FDX1's certainly not lacking anything either.
Alas, I'm not quite sure what to say. As a package, the FDX1 is probably the best single-DD IEM I've heard. It has a well-done, balanced tonality and ample technical chops; it's an "objectively" good IEM if there ever was one. And yet...I simply can't get behind it. It sounds boring and uninspired to my ears, lacking in that special sauce the KXXS, ER2XR, heck, even the MH755 all have. From the way the FDX1's transients decay too quickly, to the resulting, ever-so-slightly-off timbre and lackluster bass, it all screams a little pretentious, cold to me. Maybe I'm just not as cultured as I'd like to think when it comes to my sound. Shoot me.
Score: 5/10
Starting from here and going forward, impression posts will simply have a preference score as I generally haven't finalized all my thoughts on the IEM.
