Premier sound quality + portability + ANC? Yessir.
As an audiophile, you're often faced with tough choices—sacrificing sound quality for portability, dealing with latency in wireless connections, or struggling with noise cancelation that compromises your music. The Moondrop Ultrasonic Hybrid ANC IEMs are designed to solve these problems. With a blend of advanced drivers, high-resolution transmission protocols, and intelligent noise-canceling technology, the Ultrasonic makes it so you don’t have to choose between convenience and top-tier audio performance.
FRA direct-radiation balanced armature tweeter
At the heart of the Ultrasonic’s pristine high-frequency response is the FRA direct-radiation balanced armature tweeter. Utilizing a lithium-magnesium alloy diaphragm, this driver delivers a wider ultra-high-frequency range by reducing standing waves—a common issue in traditional balanced armature designs. The result is an extended yet natural treble that lets you catch every detail.
13mm sapphire diaphragm dynamic driver
For a full-bodied sound across the bass and mid-range frequencies, the Ultrasonic relies on a 13mm sapphire-coated dynamic driver. This driver, combined with an equidistant transmission two-way crossover, ensures accurate phase connection and restores the soundstage and timbre with impressive clarity. Whether it's a thumping bass line or sultry mid-range vocals, the Ultrasonic keeps it all in perfect harmony.
LDAC high-definition lossless transmission
High-resolution music deserves high-resolution transmission. With support for the LDAC codec, the Ultrasonic can handle bit rates as high as 990kbps, transmitting 24-bit/96kHz audio files with ease. This means you get the full dynamic range and detail of your favorite tracks, without any loss in quality during transmission. No wires, no problem.
Low delay, high-fidelity audio
When it’s time to switch gears, the LC3 low delay high-definition audio transport protocol is ready to provide a seamless experience. Designed for the new generation of Bluetooth LE Audio, LC3 ensures significantly lower latency while maintaining excellent high-fidelity signal transmission. So whether you're in game mode or streaming music, you can trust that Ultrasonic will deliver—on time and in full.
Wide-band ANC with lossless quality
Noise cancellation that doesn’t sacrifice sound quality—that’s the promise of the Ultrasonic’s wide-band ANC. By opting for a single feedforward noise cancelation method, these IEMs avoid the bass loss typically associated with feedback designs. Moondrop’s acoustic engineers have fine-tuned the system to achieve excellent noise cancellation while keeping your music quality intact.
Ambient sound transparency mode
Sometimes you need to stay aware of your surroundings without hitting pause. Ultrasonic’s ambient sound transparency mode has been fine-tuned to bring you the details you need—from traffic sounds to conversations—without distorting your music.
Easy switching of five tunings
With the Moondrop Link APP, you can switch between five different tunings, each crafted for specific listening preferences. Whether you’re after cleaner tones with “Monitor” or craving the atmospheric bass of “Club,” the Ultrasonic makes it easy to dial in the sound that suits your mood.
Seamless connection and reconnection
The Ultrasonic IEMs are built for convenience. Automatic reconnection and seamless switching between monaural and binaural modes ensure you never miss a beat. Plus, thanks to mirror image technology, your connection stays strong even when one or both earpieces return to the charging case.
