ddHiFi E13P (Memory) 13mm Super Linear Planar Driver HiFi Earphones Compatible with USB-C Smartphones and Other Devices, Supports Microphone Calls

Memory is an in-ear earphone with a semi-in-ear fit design that combines a side-filing sound tube and ear tips that press flat into the ear, creating a hybrid in-ear and semi-in-ear style. Despite its 13mm flat speaker, its ultra-compact design provides a comfortable fit even for users with small ears. This innovative driver combines the strengths of traditional planar magnetic and dynamic drivers. It achieves 10 times the electro-acoustic efficiency of traditional planar drivers, delivering a wide dynamic range even at low input power. It achieves high resolution and ultra-low distortion with a total harmonic distortion (THD) of less than 0.05% across the entire frequency range. It delivers outstanding performance in actively driven in-ear earphones. *Chinese Utility Model Patent (No. ZL202322999191.4)* The earphones' USB-C plug is compatible with iOS and Android smartphones, tablets, and computers. The built-in professional DAC/amplifier chip, the CS43198, supports 32-bit/384kHz lossless decoding. The cable includes a built-in microphone and in-line remote for calls, recording, and music playback and pause. In addition to digital tuning using DSP technology, ddHiFi has developed a shielded cable specifically for Memory earphones, combining a high-resolution decoding plug with a highly efficient flat unit to achieve retro tuning sound characteristics. The main cable has a triple-braided structure (one cable is dedicated to the microphone/inline remote control), and the left and right channel conductors are continuous inside the inline remote control without any breaks, extending to the full metal chamber of the earphone body and completely sealed within the chamber. Early generations of products are fondly remembered for their timeless design, but today's retro products are more than just reproductions: they combine precision engineering, professional-grade speakers, enhanced ergonomics and durable materials to reinterpret these classics for a new era.
