HiBy W4 Review: The Ultimate Portable DAC/AMP for HiFi Audio (2026)

Are you tired of compromising between the convenience of wireless audio and the superior quality of wired HiFi? HiBy W4 is here to change the game, offering a portable DAC/AMP that seamlessly blends both worlds. But here's where it gets exciting: this sleek device isn't just a tech gadget—it's a fashion statement, an everyday carry (EDC) accessory that turns heads with its bold, contrasting design. And this is the part most people miss: it’s not just about looks; the W4 is packed with features that cater to both audiophiles and casual listeners alike.

HiBy W4 is designed for versatility, featuring a clip-on and magnetic attachment system. Clip it to your bag, belt, or shirt for on-the-go use, or attach it magnetically to compatible smartphones or cases, transforming it into a 'MagSafe'-like accessory. One standout feature is the Uncharge Mode, which isolates the power supply from your smartphone, preventing battery drain and reducing interference—a game-changer for long listening sessions. With a built-in 1500mAh battery, the W4 ensures you enjoy your music for hours without interruption.

The device’s 2-inch touchscreen is a rarity in the DAC/AMP category, offering full-featured operation and album display in Bluetooth mode. This means you can control pairing, playback, and settings directly on the W4, enhancing user experience significantly. But here’s the controversial part: while some may argue that a touchscreen on a DAC/AMP is overkill, HiBy proves it’s a practical addition that simplifies interaction, especially for those who value convenience.

Under the hood, the W4 is a powerhouse. It integrates dual Cirrus Logic DAC chips (CS43198) paired with dual headphone amplifiers, supporting PCM up to 768kHz/32-bit and native DSD512. Dual low-phase-noise crystal oscillators ensure precise audio playback, while 3.5mm single-ended and 4.4mm balanced outputs cater to a wide range of headphones. In balanced mode, the W4 delivers up to 475mW of power, effortlessly driving even demanding in-ear monitors.

For wireless enthusiasts, the W4 adopts Qualcomm’s flagship QCC5181 Bluetooth chipset, supporting Bluetooth 5.4 and a suite of high-quality codecs like aptX Adaptive, Snapdragon Sound, and LDAC. This ensures high-resolution audio transmission with minimal latency, making it a reliable choice for wireless listening. But here’s a thought-provoking question: With wired audio still considered superior by many, can the W4’s wireless capabilities truly rival its wired performance? We’d love to hear your thoughts in the comments.

Priced at just $99 USD, the HiBy W4 is now available on HiBy’s official online store. Whether you’re a wired purist or a wireless advocate, this device promises to redefine your audio experience. Will it live up to the hype? Only one way to find out.
