Memory
Semi-In-Ear Planar IEMs
Wired Earphones – Compatible with USB-C Devices
Memory is a pair of in-ear earphones designed with a semi-in-ear fit, featuring a side-firing sound tube paired with ear tips—making it a hybrid between in-ear and semi-in-ear styles. Despite housing a 13mm planar driver, its ultra-compact design ensures comfortable wear even for users with smaller ears.
Brand Collaboration – MOONDROP’s Self-Developed 13mm Ultra-Linear Planar Driver
This innovative driver combines the strengths of traditional planar magnetic and dynamic drivers. With 10x higher electroacoustic efficiency than conventional planar drivers, it delivers wide dynamic range even at low power. Its total harmonic distortion (THD) remains below 0.05% across all frequencies, ensuring high resolution and ultra-low distortion — making it a standout in active-drive in-ear earphones.

Built-in DAC – High-Integration Plug
The earphone’s USB-C plug is compatible with iOS/Android smartphones, tablets, and computers. It features a built-in professional DAC/amp chip CS43198, supporting up to 32-bit/384kHz lossless decoding. The cable also includes a microphone and inline remote controls for calls, recording, music playback, and pause functions.
ddHiFi-Tuned Sound – DSP & Custom Cable Design
The high-resolution decoding plug paired with the high-efficiency planar driver aims to deliver a vintage-inspired sound signature. Beyond digital tuning via DSP technology, ddHiFi has specially developed shielded cable for the Memory earphones. The main cable employs a triple-strand braid (with one strand dedicated to the microphone/inline controls), while the left and right channel wires pass uninterrupted through the inline remote control without any soldered breaks, extending all the way to the earphones’ full-metal chambers where they are hermetically sealed.
Memory – A Fusion of Retro & Modern
The reason why early-generation products are fondly remembered lies in their timeless designs. However, retro-inspired products in the modern era are far from mere replicas. We combine precision engineering, professional-grade speaker, enhanced ergonomics, and durable materials to reinterpret these classics for a new age.
The Mysterious Indicator Light
The base of the USB plug features a ring-shaped LED indicator,
Blue: Standby mode
Green: PCM decoding mode
Red: Native DSD output
Included Retro Carrying Case
Inspired by classic cassette players, the ultra-compact case blends vintage aesthetics with modern colors. Made of premium synthetic leather and YKK zippers, its dual-compartment design keeps the metal earbuds separated to prevent scratches.
