HiFiGo DUNU Falcon Ultra 1DD in-Ear Monitors, Upgraded Single Dynamic Driver with Magnesium Alloy Diaphragm IEMs in-Ear Earphones (Klein Blue)

TLDR: Honestly, this is what I would be expecting from the yet to be released IEM that is named for that time just before nightfall. Basshead's rejoice. Finally found a unicorn, that does justice to the intro of "Enter Sandman". If you’re a Dunu fan, the Falcon Ultra is a must, for the collection. I actually placed it higher than the 😭 O.G. ZenMy target:As a reflection of growing up in the club scene of N.Y.C., circa 1980's. I like a visceral thump and rich vocals. Back then "neutral" was not a part of the vocabulary. Also, I’m plagued with a sensitivity to some of the upper frequency bands, which fatigue me, if the vocals are shouty. That’s not to say that I’m willing to sacrifice the details, like the nuances, in the intro to “Wanted Dead or Alive”, Bon Jovi. I want it all (Sub-bass, a good pinch of mid-bass, vocal presence, non-fatiguing detail retrieval & a wide presentation), but my priority has become IEMs that have not forgotten the lower end of the frequency response range. As a lot of the current offerings concentrate their efforts (like the Zen Pro) on a reduced mid-bass and more emphasis to the mid to upper frequencies, for the sake of detail retrieval & "airiness".I felt my journey for a single dynamic driver IEM had already reached it's apex. As I already have the: Dunu (O.G.) Zen, FiiO FD5 & 7, JVC HA-FD01 & the FiiO JD7sidenote: The Dunu Zen Pro is not in my collection because the re-tuning of the O.G. Zen. strayed from my target. From Dunu's product page for the Zen Pro, "...tuning revisions that address user concerns about a darker than expected tonality and not enough upper treble presence,"But my interest was peaked, when a reviewer on HeadFi.org pointed out that the Dunu Falcon Ultra was built upon the same foundation (ECLIPSƎ model) as used in the Zen and Zen Pro and could be a better driver, from lessons learned, from the Zen series.My review:Sssibilance: I use a song where the S's are differing degrees of hissy on all of my IEMs. Not so on the UltrasSub bass: enough head rattle to put a smile on any basshead's face, without having a prolonged decay. Really reminiscent of a good 15" kevlar sub, vs. a run of the mill 12"Mid bass: for me, this is the secret sauce, to the Ultras. The Ultras support the vocals, true to the artists, like Toni Braxton & Sinatra. While keeping the integrity of artists like Dolly Parton intactMid Forward vocals: Artists like Phil Collins can come across as being too synthesized, on some sets, without that attention to the mid-bassMore details than I would expect from a single DD, given the afore mentioned sub & midbass presence.Soundstage 7.25 out of 10.; this so subjective, that I would recommend compiling other reviews.O.G. Zen vs. Ultras (on BTR7):Zen wins on width, but I'm not kicking the Ultras out of bed. Ultras tuning is more sultry, similar to using a tube amp. The Zen has more sparkle, up top.Sub: (this surprised me) Ultras wins, hands down. It's that attention to the complimentary mid-bass, in the Utlras, that brings the sub-bass across the finish line.Midbass: on the Zen it's cleaner. But I appreciate that small boost in the Ultra's midbass; it brings home vocals, mud free.Overall: the Ultras has a richer/fuller mids and vocals. The Ultra's playback is the vinyl, stereophonic version, vs. the Zen's (I'm exaggerating, but is evident in A/B testing) MP3 playbackRunning balanced is a necessity. On the 3.5mm SE connection I found the playback to be confined.Very hard (at least my copy) to swap from the 3.5mm to 4.4mm. Will probably loosen up with use.[Short term update]Always a point of contention, but I feel the dynamic driver definitely benefits from a break in period. After about 50 hrs. the bass region has really benefited. This is probably a reflection on other IEMs being more V shaped (equating to a drop off of the mid-bass), but the mid-bass really compliments the sub-bass well.The included brown pouch is a must, for pocket carry, to protect the finish on the Falcon Ultras.

This is a v/w shape done great. A warmer tanchjim oxygen with great bass quality and the perfect quantity for all genres of music. Vocals are more intimate than the oxygen, especially with the gold nozzle. I prefer the blue nozzles with spinfit w1 eartips, but the included tips all work well (s and s being the best match, candy tips if you want to tame the highs and focus more on the bass. The highs are airy and sparkly, bass is very satisfying and punchy. Mids sound natural to my ears, not stuffy and wonky like the fiio fh3 (though this is most noticeable on YouTube videos and such with speaking, I still love the fh3 and that can be fixed with eq). You can tell this has a high quality dynamic driver, it has great extension. Detail is pretty good for a single dd, but not aful performer 8 levels. The cable is decent, I wish it wasn’t quite as “kinky”, but it doesn’t seem to tangle. I just wish it was a bit softer and unraveled strait. The mmcx connection seems to be of good quality like a higher end fiio (fh9), so it doesn’t feel loose like the sennheiser mmcx. I’m not worried about connection issues at all. You get a large amount of eartips to choose from, but I found spinfit w1 to be the best fit for this. These are also really small and easy to fit comfortably. If you want a higher quality iem with a natural sound that is dynamic/musical for music/movies/gaming this is a great choice. It’s an upgrade over the moondrop kato and imo better than the tanchjim oxygen.

Returning this because most accessories were in the box but the IEMs were missing

The sound quality of the Dunu Falcon Ultra feels much greater than the price tag it is at. The bass is phenomenal and easy to pick apart the frequences. The treble is incredible but I can only stand it for a handful of songs before it becomes too much.The biggest issue for me is fitment. They are very heavy yet surprisingly small. Trying to get these to fit in my ear snugly was impossible. No matter which eartip I used (and I tried every single one included, which is a lot) I could not get it to fit well or seal fully. I could get them to seal if I really worked them into my earholes tightly, but it became uncomfortable very quickly. Also they would eventually work themsleves back out due to their weight.I really wanted to like these but their fitment made it too difficult for me to enjoy them.Examples of IEMs that fit my ear well:Truthear Hexa - These fit into my ear very well. They are comfortable for extended wearing sessions. I use the medium silicone ear tip included and it seals perfectly.Thieaudio Legacy 2 - Probably the best fitment in my ear of all IEMs. These feel like they sit in my ear the most naturally. I could wear these for days and never feel worn out. I use the medium size silicone ear tips included and they seal and fit perfectly.Thieaudio Hype 2 - These are very similiar to the Legacy 2 but just ever so slightly larger in depth. However, the overall shape is basically identical and these fit very well. I use the medium size ear tips and they seal perfectly. The nozzle on the Hype 2 is larger than that of the Legacy 2. So while the outer size of the tip is identical to that of the Legacy 2, the inner diameter is larger and I feel like it takes a little bit away from the softness of the tip, causing it to feel a little more rigid in my ear. It is still extremely comfortable and I can wear them for extended periods of time easily.

Fenomenal el sonido, lo único mal el cable se enreda mucho pero es aguantable
