Choosing iem earphones often comes down to one practical trade-off: do you want the flexibility of app-based sound control, or the simplest possible connection? The Moondrop MAY takes a feature-forward route with hybrid drivers, a USB-C DSP cable, and a detachable earphone connection. That makes it worth considering for listeners who want digital customization built into a wired setup.
Quick verdict
The Moondrop MAY Hybrid IEM In-Ear Earbuds USB-C Earphones DSP HiFi Planar Driver is a focused choice for someone looking for an audiophile IEM with USB-C connectivity and adjustable sound through the Moondrop Link App. Its listed price is USD 122.67. The main limitation is equally clear: the connection is USB-C wired, so the earphones are designed around that specific interface rather than a general-purpose analog plug.
Product note
Moondrop MAY Hybrid IEM In-Ear Earbuds USB-C Earphones DSP HiFi Planar Driver

The strongest reason to choose the MAY is its combination of a 10mm sapphire diaphragm dynamic driver and a 6mm annular planar driver. The description pairs those two drivers with a high-performance USB-C DSP cable and app-based customization, giving you a way to adjust the sound profile through the Moondrop Link App. That is a concrete advantage for listeners who want more control than a fixed wired tuning provides.
The trade-off is the USB-C format itself. The listed connectivity is USB-C wired, and the cable is approximately 1.2 meters long. That keeps the product centered on a digital wired setup, while the 0.78mm 2-pin connector makes the earphone side of the cable detachable. If you specifically want a traditional analog connection, this model does not present itself that way.
Who it suits
The MAY makes the most sense for listeners who use USB-C audio devices and want a wired in ear monitor with built-in DSP features. It is also a natural fit for anyone interested in a hybrid IEM earphone rather than a single-driver design. The Moondrop Link App is the key usability feature here: it lets you customize the sound profile instead of treating the earphones as completely fixed.
For a simpler setup, the number of moving parts may be more than you need. Along with the USB-C DSP cable, the product supports up to 32-bit / 384kHz PCM decoding. Those specifications will appeal to shoppers seeking a clearly defined digital audio setup, but they are not a reason by themselves to choose the MAY over every other wired earphone.
Meaningful trade-offs
The MAY gives you three notable elements in one package: hybrid driver configuration, USB-C wired connectivity, and app-based DSP control. Its silver finish and detachable 0.78mm 2-pin connection round out the listed design details. The important compromise is that the product's appeal depends on wanting those specific features; shoppers seeking a basic plug-and-listen earphone may find the DSP-focused design less relevant.
Bottom line
At USD 122.67, the Moondrop MAY is best suited to a listener who wants hybrid IEM earphones with USB-C DSP and sound-profile adjustment. Choose it for that combination; pass on it if your priority is a conventional analog wired connection.
