MOONDROP ALICE True Wireless Stereo

No gimmicks! Just sound quality

What's lacking in the development of modern TWS? Sound quality!

Most brands claim that their TWS deliver high-fidelity sound, but is it true? Does superior sound quality depend solely on high bit rate transmission? No! The SNR of TWS SOC can't reach 16bit, so high bit rate transmission doesn't bring significant improvement.

Can the sound quality be improved by adding dynamic drivers and balanced armature hybrid drivers or planar drivers? No! The performance of the transducer is greatly limited by its tiny size. It makes no sense to increase the inaudible bandwidth by adding extra high-frequency drivers.

Due to the lack of stacking space, the thickness of the dynamic driver in TWS, especially those with noise-cancelling, is compressed to less than 3mm, and the space left for magnetic circuits and diaphragm vibration is even more limited. All these hardware factors limit the sound quality of TWS.

ALICE is a ground-breaking no-compromise product that optimizes transducer performance, SOC output and DSP filter adjustment to deliver the highest sound quality possible. It's a true flagship TWS delivering exceptional sound quality.

  • Equipped with a ULT super linear dynamic driver
  • Third generation diamond-like composite diaphragm
  • Tuning based on VDSF Target Response
  • Utilizes soundstage Virtual Sound Algorithm VDSF+
  • 10 kinds of switchable classic reproduction tunings
  • Open professional parametric equalizer
  • Qualcomm's flagship Bluetooth chip QCC5151
  • aptX Adaptive high bit rate transmission protocol
  • Noise-cancelling of beamforming ENC microphone
  • Ultra-long battery life
  • Wireless charging

Equipped with a High-Performance U.L.T. Super-Linear Dynamic Driver

ALICE adopts the same patented ULT super-linear dynamic driver used in MOONDROP's flagship dynamic driver earphone KATO. Designed and developed in-house, the driver features a more efficient internal and external magnet composite magnetic circuit, a more linear air flow structure, a larger brass internal acoustic cavity, a lighter ultra-fine imported CCAW voice coil, and a high-frequency phase waveguide. Through FEA finite element simulation combined with repeated experiments and verification, it presents muscular dynamics, rich details, and surprising performance regardless of nonlinear distortion or linear distortion.

In adopting this ULT super-linear dynamic driver from the flagship wired earphone to ALICE, only the signal output connector was modified, and its electroacoustic transduction structure and acoustic performance were inherited intact, giving ALICE a far superior sound quality

Third generation Diamond-Like Carbon (DLC) Composite Diaphragm

The ULT super-linear dynamic driver features a newly designed high-performance DLC composite diaphragm that uses DLC and two other materials for different parts of the diaphragm. This results in high rigidity, high damping coefficient and light weight, and a comprehensive acoustic performance that exceeds even that of beryllium.

The third-generation DLC composite diaphragm is based on different material characteristics, simulated by FEA finite element analysis, and obtained after repeated experiments, which results in enhanced highs performance, improved dynamic range, a boost in overall acoustic damping, and strengthened instantaneous performance.

Featuring Qualcomm's Flagship Bluetooth SOC Chip QCC5151

With the powerful built-in DSP performance of the QCC5151, ALICE can attain richer sound quality extensions and compensate for the physical limitations of in-ear monitors by adding a variety of different filter algorithms, thus bringing a more realistic and pleasant listening experience and richer playability.

Equipped With Soundstage Virtual Sound Algorithm VDSF+

ALICE is equipped with new generation of VDSF+ (Virtual Diffusion Sound Field Technology), which further improves the soundstage performance by simulating the differences of direct sound at the end of the acoustic transmission path.

* The VDSF+ can be easily turned on/off by touch operation.

Integrated Acoustic Structure

In contrast to traditional TWS, ALICE uses the same integrated acoustic cavity structure found in high-fidelity wired headphones. The driver and related acoustic structures have priority over the component and battery stacks. In this way ALICE not only avoids the negative impact of sensors and FB components on acoustic conduction, but also ensures a more optimized acoustic conduction path.

Unlike traditional TWS, ALICE is the same as standard in-ear monitors, facilitating replacement of the stock eartips with third-party alternatives, thus ensuring an optimum custom fit and an improvement in treble/bass performance.

Precise Tuning

The VDSF Target Response, which is based on the international standard head-and-trunk simulator measurement of the related transfer function of diffusion from HRTF head and the adjustment of ear experiment, is the target reference of the frequency response of MOONDROP earphones.

Building on MOONDROP's deep technical experience in acoustic adjustment of in-ear monitors, and with the support of high-performance DSP, ALICE is able to achieve a highly consistent VDSF Target Response, bringing an unprecedented excellent tuning.

10 kinds of classic tuning available

Through the MOONDROP Link app, ALICE offers 10 kinds of tuning created by Mr. Luo, a senior tuning engineer at MOONDROP. With the exception of the default tuning, all others are tuned according to well-known classic headphone models, to ensure that users can not only enjoy the standard default tuning, but also experience those of classic well-known headphone models.

Open-Professional Parametric Equalizer

Should any of the 10 switchable tunings not be to your taste, you can use the MOONDROP Link app to access the professional parametric equalizer and adjust the sound more freely and flexibly that common EQs.

apt X Adaptive High-Bit-Rate Transmission Protocol

ALICE is compatible with Qualcomm's aptX Adaptive transmission protocol, and can switch between high bit rate and low latency and support up to 24bit/96kHz, thus greatly reducing the loss of sound quality caused by Bluetooth.

ENC Beamforming Dual Microphone

Utilizing the built-in Qualcomm ENC of the QCC5151, and relying on dual MEMS microphones on each side to collect environmental noise and voice, ALICE features an ENC function, which results in clearer, less noisy calls.
