The DUNU Alpha 3 is a wired flathead earbud with a 14.2mm dynamic driver and a liquid crystal polymer composite diaphragm in a stainless steel and aluminum alloy shell, rated at 32Ω and 105dB. It suits listeners who like the open, non-sealing fit of classic earbuds, in Black (3.5mm or 4.4mm plug) or limited-edition Cherry Blossom Pink (3.5mm).

Who the DUNU Alpha 3 is for

  • Earbud fans: The flathead shell rests in the outer ear instead of sealing the canal, and it holds a 14.2mm dynamic driver with a liquid crystal polymer composite diaphragm.
  • Phone and dongle listening: Rated at 32Ω and 105dB ±1dB, it is an easy load for USB-C dongles and portable players.
  • Balanced sources: The Black version is also offered with a 4.4mm balanced plug for DAPs and dongles that have a 4.4mm output.
  • Color collectors: Cherry Blossom Pink is a limited-edition color that DUNU pairs with a high-purity OCC copper cable and a 3.5mm plug.
  • Skip it if: you need noise isolation or want to change plugs later; flathead earbuds do not seal the ear canal, and the 3.5mm or 4.4mm plug is chosen at purchase.
