    Pros - excellent resolution and detail, extension in both extremes, elegant and attractive design, build quality, tip selection
    Cons - sticky cable, slightly unnatural midrange timbre

    I'd like to thank Vivian from Dunu for providing me with the Falcon C to sample and review. All words are my own and my honest opinion.​

    The Falcon C comes in a metallic silver cardboard sleeve, which slides out to reveal a matte-black folding box secured by a magnetic latch. Upon opening the box, you are presented with the IEMs themselves and the metal carrying case. The metal carrying case itself is not very pocketable due to its height and rigidity, but is a nice addition included with the overall package. The convex aluminum surface is somewhat thin and compressible, pressing down on it will cause it to go flat and spring back once pressure is released. It is internally lined with a thin felt surface, and closes by a seemingly snap-lock system.

    Within the metal case are the Falcon C's accessories. You get a 3.5mm to 6.3mm adapter, flight adapter, and a plethora of tips. There are 3 pairs (S/M/L) of the default blue-core 'bass' tips (medium bore), 3 pairs (S/M/L) translucent-grey 'clarity' tips (wider bore), and 4 pairs of (XS-L) Spinfit tips. The IEMs themselves also come with a pair of medium blue-core tips installed, so there are a total of 11 pairs of tips included in the box (impressive)!


    The Dunu Falcon C is very well put together. It sports an attractive, dark and sleek design that looks great -- it is undoubtedly the first Dunu IEM that has caught my eye. The housing material is formed with 'liquid metal', perhaps similar to that of the Campfire Vega / Dorado / Lyra II line -- it is smooth and cool to the touch, feeling very premium regardless of its asking price. The housings are coated in a dark-grey shade, with a hint of metallic tinge beneath the surface. The metal shells are surprisingly hefty, but not to the point that they are noticeably heavy in the ear. I applaud the design of the Falcon C, as it is both pleasing to look at and comfortable to use.
    The housing is ergonomically shaped, reminiscent of a curved and smoothed teardrop. Once I was able to find the correct tips, they fit very securely without any discomfort. The angled MMCX connectors are also a great help to this. The design sits flush with my ears, I would go as far as to say these are sleepable IEMs.

    On the proximal side of the housing, there are a few visible seams that are apparent. They aren't rough or unrefined however, as the housings remain entirely comfortable. There is also a large driver venting, covered in a flat silver sheet with perforations. Left-right indicators are clearly legible and engraved into the surface.


    The Falcon C's cable is a mixed bag for me. It is a good-looking cable, shaded in dark brown with the internal wiring subtly glimmering from beneath the sleeving. It is also soft and quiet, reducing cable noise to a bare minimum. The ~45 degree angled MMCX connectors are great for ergonomics and pair well with the housing design. However, it is not without its issues. The cable itself is fairly springy, it tends to create funky loops when dangling between your ears and DAP/phone pocket (it is caused by rotation / mild twisting of the cable). Additionally, the material has a 'sticky' rubber texture, tending to grab onto the things it touches -- specifically clothing and itself. When the cable has mild tangles or loops, you can't really run your fingers through the wire to sift out the kinks; with the Falcon C's stock cable, you have to pick the wire tangles apart carefully as the rubber tends to grip to itself.



    Personally am not a huge believer of burn-in, but I gave the Falcon C ~90 hours of runtime before sitting down for a final listening session. I didn't hear that much of a difference between initial unboxing and current sound -- if something changes in the next 50 hours, I will update the review.

    The Falcon C is v-shaped in tonality, with excellent resolution and clarity. Lower midrange sits behind in the mix, creating a spacious and clear sound with above average imaging. Bass is enhanced with a favor towards midbass; upper midrange rises gently carrying momentum noticeably into the lower treble, which extends gently beyond into the upper treble.


    The Falcon C's bass is one of its stronger assets. Subbass extends deep, though the lowest registers aren't as pronounced, still rumbling with authority. Midbass is impressively impactful and agile; speed is definitely above average, resulting in a relatively tight and technically apt presentation. Bass presentation will never come off as slow or syrupy. Bass is also fairly dynamic, it does not come off as one-noted or 'wooly' in texture like some other dynamic IEMs (an issue I felt to be present with the Pinnacle P1/X). In terms of quantity, the bass is undoubtedly lifted above neutral. Falcon C's bass quantity will likely please many low frequency lovers, but might not have enough for the most diehard bassheads.


    Midrange is usually tricky to get right, as my ears are more sensitive to noticing quirks and mishaps in the mids. Being an overall v-shaped IEM, the Falcon C's lower midrange is subdued in relation to its neighboring bass and upper midrange frequencies. Upper midrange is forward with excellent texture and resolution, though may come off as slightly tizzy at times. Female vocals are stand out as airy and detailed in a track, while male vocals have a clear biting edge but less body. This trait presents itself as a double-edged sword, resulting in an occasional metallic timbre associated with vocals.


    Falcon C's lower treble carries its momentum from the lifted upper midrange, with noticeable emphasis on its lower treble. For this reason alone, I would not recommend the Falcon C to those who are sensitive to treble; it really dances on the borderline to sibilance for me. However, it offers fantastic clarity throughout its treble presentation, without any noticeable or substantial dips / valleys. Resolution is nothing short of impressive, especially in its price bracket. Extension into the high frequencies is not lacking -- it presents itself with an above-average sense of spaciousness / airiness and sufficient sparkle.

    The Dunu Falcon C is a beautifully designed universal IEM, sporting a v-shaped tonality (leaning towards bright) with excellent resolution and extension in both directions. Build quality feels premium in both quality and aesthetics, its metal shells coated in a dark matte-grey and detachable MMCX cables reassuring durability. Bass is impactful and quick, with fantastic treble detail and extension. Falcon C's Achilles heel is within its occasionally energetic upper midrange, lending itself to come off as unnatural. But for those looking for a premium IEM with impressive bass and treble performance in this price bracket, it becomes seriously hard to rival the Dunu Falcon C in its strengths.
