Choosing iem earphones is less about chasing a driver label and more about matching the earphones to how you connect them and how much control you want over playback. The Moondrop MAY and ROSESELSA Aurora Ultra take different approaches to that setup, so the key question is simple: do you want built-in digital control, or a setup that includes extra conversion hardware? This head-to-head focuses on that practical decision, then separates the smaller cable and specification differences that may matter after the connection is settled.
Quick verdict
Pick Moondrop MAY when you want USB-C wired listening with DSP and sound-profile adjustment through the Moondrop Link App. Pick ROSESELSA Aurora Ultra when you want a 3.5mm jack and an included 3.5mm-to-Type-C DAC dongle. Both are hybrid IEM earphones, but these connection and control differences are more useful for choosing than the shared driver category.

Where each product wins
- Moondrop MAY: Its decoding support is listed up to 32-bit / 384kHz PCM, giving it the clearer specification-led appeal for listeners who want that stated digital capability.
- ROSESELSA Aurora Ultra: Its detachable 5N OCC cable with 0.78mm 2-pin connectors is the stronger fit for shoppers who place cable construction and a detachable connection high on the list.
Moondrop MAY
Moondrop MAY is worth choosing when the combination of hybrid architecture and decoding support matches your priorities. Its specified driver configuration pairs a 10mm Sapphire dynamic driver with a 6mm annular planar driver, and decoding support is listed up to 32-bit/384kHz PCM. That gives shoppers a concrete reason to focus on the MAY if those specifications matter more than simply shopping by the word hybrid. A limitation is the approximately 1.2m Y-type cable: it may not suit every listening position or preferred lead length. The silver color is part of the stated configuration, so shoppers who care about appearance should factor it in. Choose the MAY for its driver-and-decoding combination, without treating the numbers alone as a promise of sound quality.
ROSESELSA Aurora Ultra
ROSESELSA Aurora Ultra is a sensible choice when a detachable cable matters. The cable is described as 5N OCC with 0.78mm 2-pin connectors, giving the setup a concrete cable detail for shoppers who prioritize that construction. Its hybrid configuration pairs a 10mm dynamic driver with a 6mm planar magnetic driver, while the stated frequency response is 20Hz-20kHz. The limitation is the stated impedance of 30Ω ±15%: shoppers who need a particular impedance target should include that figure in their decision. Choose Aurora Ultra when its cable construction and electrical specifications fit the listening plan; the numbers themselves do not establish a sound-quality winner.
Final choice by use case
- Choose Moondrop MAY if your main use case is a USB-C wired source and you want DSP sound-profile adjustment via the Moondrop Link App.
- Choose ROSESELSA Aurora Ultra if your main use case starts with a 3.5mm jack and you specifically want the included 3.5mm-to-Type-C DAC dongle.
- If price leads the decision, choose Aurora Ultra; if app-based control leads it, choose Moondrop MAY. The hybrid driver category is shared, so the connection and control setup should make the final call.
