Portable Bluetooth DAC Amplifier

The LORDWORLD W4 combines a Bluetooth 5.4 receiver with dual CS43198 DACs and dual SGM8262 amplifiers. It switches between wireless and USB UAC 1.0 or 2.0 modes for smartphones, computers, tablets and digital audio players. A 2-inch touchscreen provides direct control over playback and settings.

Upgrade from basic dongles

This unit replaces simple Bluetooth adapters or single-chip USB DACs by adding aptX Lossless and LDAC codec support, cVc noise reduction for calls, NFC pairing and a physical charging-lock switch. The jump is worth it when you need balanced 4.4 mm output plus 3.5 mm single-ended, DSD512 and PCM 768 kHz 32-bit decoding, and automatic power-follow operation in a vehicle.

For critical mobile listening

It suits listeners who want high-resolution wireless and wired audio from one pocket-sized device with a tactile screen interface. Buyers who only need a basic USB-C dongle without Bluetooth, or who require integrated local storage for offline playback, should look at something else.

What headphone connectors does the W4 provide for wired listening?

The W4 has a 3.5 mm single-ended jack and a 4.4 mm balanced jack so you can plug in either standard or balanced headphones directly.

Use the 2-inch touchscreen to select the input mode; the unit supports seamless switching between Bluetooth 5.4 and UAC 1.0 or 2.0 USB DAC operation without re-pairing.
