A Professional-Grade Chip to Do the Heavy Lifting

The xDuoo X3II utilizes an AK4490 chip from AKM as the digital-to-analog converter. This chip is one of the best on the market, allowing for high-definition audio, with a wide soundstage and precise delivery of the music.

Two Hi-Fi chips from Texas Instruments (OPA1652 and LMH6643) also contribute to the OP+BUF circuit utilized in this music player. They help with the reduction in distortion and noise while adding to the musical detail and the powerful amplification of audio signals.

Supports All Major Audio Formats, Including Lossless

The xDuoo X3II is capable of playing back essentially all popular and enthusiast audio formats. It supports relatively common formats such as MP3, AAC, WMA, OGG, and more. It can also handle CUE, M3U, and M3U8 files.

Lossless formats such as FLAC, DXD, WAV, APE, ALAC, and AIFF are supported up to 32-bit at 384kHz. DSF and DFF audio are also entirely compatible.

Audio Tuning in Your Hands

You get the power to adjust your audio to your exact taste, with a ten-band equalizer right at your fingertips. Besides that, the xDuoo X3II allows you to select from 18 different sound effects, so you can get audio quality that sends maximum pleasure to your ears.

Bluetooth 4.0 Audio Transmission

Whether you’re looking to transmit or receive audio through Bluetooth, the X3II has you covered.

It can transmit lossless Bluetooth audio to headphones, a car stereo, or speakers by turning into a digital turntable.

You can also connect a smartphone to it via Bluetooth, which makes it easy to enjoy your mobile audio on playback devices and at high-definition quality too.
