 Feature：1. MagSafe-Style Snap-On PortabilityUnlike dangling dongle DACs that tug on your cable and swing off your phone, MD3 locks in place with 16 N52 magnets and weighs just 50g. Snap it on and go—no straps, no bulk, no awkward hangs.2. Circular Display That Shows More Than SpecsThe 1.28" fully laminated round screen doesn't just show bitrates and volume levels—you can upload photos, set wallpapers, and even run animated emojis. Spin the Vista button and turn your DAC into a personal statement piece.3. Flagship DAC Chip, Hi-Fi From Your PhoneBuilt around the ESS ES9039Q2M and four ES9603Q op-amps, MD3 hits THD+N as low as 0.00075% with a noise floor of just 1.7μV. Your phone finally gets the black background, wide dynamics, and micro-detail it deserves.4. Balanced Drive With Real PowerThe 4.4mm balanced output pumps out 180mW ×2 at 32Ω, while the 3.5mm single-ended delivers 75mW ×2—enough to drive anything from IEMs to full-size cans up to 300Ω. One device, every headphone covered.5. Pass-Through Charging While You ListenDual USB-C ports mean the bottom handles audio decoding and the top takes external power to charge your phone on the fly. Long flights, daily commutes, late-night sessions—your battery and your sound quality both stay topped up.SpecificationsChipset DAC: ESS Sabre ES9039Q2MAmplifier Chips: ESS ES9603Q ×4Input USB-C(Top): Audio Decoding/Image Transfer/ChargingUSB-C(Bottom): Audio Decoding/Image Transfer/Firmware UpgradeOutput 3.5mm Single-Ended, 4.4mm BalancedUSB Audio Class：UAC 2.0, UAC 1.0Max Sampling Rate：UAC 2.0: PCM 32bit/384kHz, DSD256(Native)UAC 1.0: PCM 16bit/48kHzMax Output Power(1kHz, THD+N＜1%) 3.5mm: ≥75mWx2 @32Ω4.4mm: ≥180mWx2 @32ΩFrequency Response 20Hz-48kHz(±0.2dB)SNR：3.5mm: ≥115dB4.4mm: ≥116dBDynamic Range：3.5mm: ≥115dB，4.4mm: ≥116dBTHD+N：3.5mm: ≤0.00075%，4.4mm: ≤0.00084%Noise Floor：3.5mm:＜1.7μV4.4mm:＜2.7μVHeadphone Impedance：16-300ΩWeight(without cable) 50g(±2g)Dimensions：70x45x12mm(2.76×1.77×0.47in)
