Flat earbuds, refined

MOONDROP's very first product a decade ago was a pair of flat earbuds, carefully designed, positively received, and fundamental to the brand's identity.

With Nice Buds, MOONDROP revisits this classic form and combines it with modern acoustic technology, structural innovation, and user-centric design.

Flat earbuds are back—and better than ever.

Powerful 15.4 mm dynamic driver with improved bass tuning

Nice Buds feature a specially tuned 15.4 mm neodymium magnet dynamic driver that improves resonance coupling in open-back earbuds and delivers a natural, smooth, and pleasant timbre. A dual damping system in the rear cavity, with an integrated airflow bass enhancement tube and four high-damping vents, precisely controls bass and mid-bass output across two frequency bands. This enables powerful, structured performance in the lower frequency range without compromising clarity in the mid-frequency range.

Precise front cover

To achieve superior sound clarity, the front cover has been redesigned with optimized multi-pore ventilation and internal waveguide channels. This structure ensures uniform airflow, stable wave transmission, and natural dispersion across the entire frequency range, resulting in improved transparency and detail reproduction.

Positioning limit for foam earbuds

With flat earbuds, it is common for the foam earbuds to shift or fall out. Nice Buds use a hub-like positioning limit design that holds the foam earbuds securely in place. This improves acoustic consistency, prevents slippage, and increases long-term wearing comfort.

Ergonomic asymmetrical fit with improved bass response

Unlike traditional symmetrical shells, Nice Buds use an asymmetrical ergonomic geometry tailored to the human ear. This allows for closer contact with the tragus and ear canal entrance, reducing fatigue and improving stability. The improved seal also enhances bass response, giving the flat earbuds a deeper, fuller sound.

Modern aesthetics with clean geometric lines

Inspired by the classic MX500 shape and updated with modern geometric principles, Nice Buds strike a balance between structure, comfort, manufacturing precision, and visual appeal. Available in transparent and black-transparent finishes, they embody simplicity with a contemporary touch.
