Disclaimer: Reviewing audio gear is highly subjective. There are many factors that influence the sound characteristics of a product, such as ear tips, fit, music choice, prior experience, and more. What I experience may not reflect what you experience, and vice versa. So please take everything I say here with a grain of salt, and always cross-reference reviews. So now, let’s proceed.



  • Effective interchangeable nozzles
  • Forgiving to poorly mixed songs
  • Impressive amount of accessories
  • Very comfortable fit
  • Engaging sound


  • Fingerprint magnet finish
  • Trebleheads might need more treble energy
  • Not for the folks who prefer neutral sound signature

I don’t normally follow announcements and read spec sheets of all new IEMs. There are just way too many releases these days, so I just blindly audition sets when there are local meetups in our area.

I was amazed when I learned these are single-dynamic driver IEMs. They are really capable, although I lack experience with single DD IEMs. But I have mostly read positive feedback about the Tanchjim Oxygen, which has a similar driver configuration.

Frequency Response

Using it with the stock S&S tips, it fits snugly. However, after long periods of time, it slides out and leaves some pain in my ears, maybe due to the somewhat stiff silicon eartips. So I changed to my tried-and-true Tri Clarion tips – these are the only ones comfortable enough for longer listening sessions in my experience.

I wasn’t too crazy about the cable either. It’s stiff, even stiffer than the BQEYZ Winter’s cable. Though the components used are high quality, with a brushed finish and interchangeable plugs being a nice touch.

The finish on the IEM’s faceplate is a fingerprint magnet, which is a shame since it’s really well made, and lightweight, and those subtle symbols around the faceplate are really appreciated.


Having used the golden nozzle, it gave me this smooth and inoffensive response – the best I can describe it is a “creamy” signature. It reminds me of my Samsung Galaxy Buds Pro earbuds’ sound signature.

Going back to the stock blue nozzle, I was listening to Wolf Alice’s “Delicious Things” from their Blue Weekend album. I noticed the treble is well controlled, with no unnecessary spikes even though this track has pretty intense highs throughout. Heck, even listening to “Thank God It’s Friday” by Ice Nine Kills, there was no piercing treble present. This song can sound really sibilant on uncontrolled tuned drivers.

Vocals are well placed for both male and female, not too forward or recessed in the mix.

The Falcon Ultra provides enough sub-bass rumble without overwhelming the lower mids.

Instrument placement is not congested, with just enough space between elements. These IEMs are really forgiving even on poorly mastered or mixed tracks.


Gaming with the Falcon Ultra, it has good technicalities. It extends well, resulting in easier opponent detection. The imaging is somewhat similar to the Bravery AE, I’d estimate around 70-75% of its overall technicalities.


There you have it! My Dunu Falcon Ultra IEM Review. Overall, I really enjoyed my time listening to the Dunu Falcon Ultra. It fits my preferred sound signature well. The IEMs are engaging enough but not to the extreme that fatigue sets in during listening. Strangely, they manage to be both engaging and inoffensive simultaneously – those words don’t usually go hand in hand in my experience.

I can highly recommend these IEMs if you listen to a wide variety of music genres. They are forgiving on poorly recorded tracks and they make your feet thump with its engaging sound.
