Hi all,
We’re excited to share a brand-new launch from Moondrop — The Moondrop Harmon Hybrid Dynamic Driver IEMs (In-Ear Monitors) are built around a trio of full-sized 10mm drivers—two for bass, one for mid-treble—each housed in its own acoustically tuned chamber.
The secret sauce is a patented four-cavity acoustic crossover system that lets the drivers blend naturally—no harsh handoffs, no smearing.
