A single-dynamic-driver IEM at around $220, near-universally praised for build, cable and accessories, and for a low end whose control and texture almost nobody criticises. Sources agree the shells are comfortable and light for their metal construction, that the driver is easy to power but scales audibly with a cleaner source, and that the finish scratches and shows fingerprints. They divide on three things: how deep the bass really goes, whether the top end sparkles or bites, and whether the stage is ordinary or close to holographic. The first two splits track the nozzle fitted; the third tracks how much power the source is giving it.
About this product
The 2023 DUNU Falcon Ultra, a single 10.7 mm dynamic-driver IEM with a lithium-magnesium alloy dome and two screw-in tuning nozzles. It supersedes — and is not — the older, discontinued Falcon Pro, and it sits above the cheaper Titan S2 and Kima 2 in DUNU's single-DD line. Sold in two finishes that share the same driver and tuning: the original polished Klein Blue stainless steel at $239.99, and the later Meteorite Titanium edition at $219.
The DUNU Falcon Ultra is a roughly $220 in-ear monitor built around a single 10.7 mm dynamic driver — DUNU's second-generation ECLIPSE design, with a lithium-magnesium alloy dome and a ring-type magnet assembly borrowed down from the far pricier Zen. It arrives in polished stainless steel, with a modular cable that ships with both 3.5 mm and 4.4 mm plugs, a large case, and a spread of ear tips generous enough that reviewers spend as much time on the box as on the sound.
It also ships with two screw-in nozzles — one steel, one gold-plated brass — and that detail turns out to explain a surprising amount of the argument about it. Measured on two independent rigs, the two nozzles are identical below about 2 kHz and roughly 2–3 dB apart from 4 to 10 kHz. Reviewers who fitted the steel one and reviewers who fitted the gold one were, in a real sense, not reviewing the same treble.
