Pre-order details

Overview

The details behind HiBy W4.

Dual-Core, Dual-Mode Versatility

HiBy W4 is an all-in-one portable Hi-Fi solution that seamlessly switches between Bluetooth receiver mode and USB audio mode. Whether your music source is wireless or wired, W4 delivers powerful headphone amplification and uncompromising sound quality in a single compact device—perfect for everyday carry.

UnCharge Mode for Cleaner USB Audio

A dedicated UnCharge lever allows W4 to run entirely on its internal battery even when connected via USB. This innovative design reduces background noise and phase interference from external power sources, resulting in purer sound while also minimizing power draw from your smartphone or computer.

2-Inch Full-Color Touchscreen Control

Unlike traditional dongles or Bluetooth receivers, W4 features a 2-inch color touchscreen for intuitive control. Playback, pairing, filters, and system settings can be accessed directly with simple taps, delivering a uniquely user-friendly experience in a portable Hi-Fi device.

Album Art Display for Emotional Immersion

In Bluetooth mode, W4 supports album art display, giving you a clear visual of track information while enhancing emotional engagement during listening sessions.

Qualcomm QCC5181 Bluetooth 5.4 Platform

Powered by the flagship Qualcomm QCC5181 Bluetooth chip, W4 supports Bluetooth 5.4 for faster pairing, stronger stability, and improved resistance to interference. Advanced low-energy Bluetooth audio technology delivers higher sound quality without increasing power consumption—ideal for music, calls, and gaming.

Full Hi-Res Bluetooth Codec Support

HiBy W4 supports Snapdragon Sound and all major high-bitrate Bluetooth codecs, including aptX Adaptive, aptX Lossless, aptX HD, aptX, LDAC, AAC, and SBC. Enjoy high-resolution wireless audio up to 24bit/96kHz across Android, iOS, and Windows platforms.

Dual CS43198 DAC Architecture

W4 integrates dual Cirrus Logic CS43198 DAC chips, independently decoding left and right channels. This fully balanced design significantly improves SNR and channel separation, delivering cleaner transients, deeper bass impact, richer vocals, and enhanced spatial imaging.

Femtosecond-Grade Clock Precision

Dual independent femtosecond-grade oscillators (45.1584MHz and 49.152MHz) ensure ultra-low jitter performance across both 44.1x and 48x sampling families, preserving timing accuracy and faithfully reproducing the original recording.

Powerful Balanced and Single-Ended Outputs

Equipped with both 3.5mm single-ended and 4.4mm balanced outputs, W4 delivers up to 475mW of driving power, effortlessly handling dynamic, balanced armature, hybrid, and planar IEMs and headphones.

Long-Lasting Battery with Playback While Charging

The built-in 1500mAh battery provides up to 6 hours of continuous wireless playback. W4 supports playback while charging, allowing it to function as a wired DAC at home and a wireless Hi-Fi device on the go.

Stylish Design with Detachable Clip

Featuring a bold, fashion-forward color-glitch design, W4 blends audio performance with modern aesthetics. The detachable metal clip allows secure wearing on clothing or bags and can be removed for flat dongle use with MagSafe-compatible accessories.

NFC & Car Audio Optimized Mode

NFC one-touch pairing simplifies Bluetooth connections. Car audio optimized mode enables W4 to power on/off with your vehicle and reconnect automatically, creating a seamless lossless in-car audio experience.

Very impressed and satisfied

I have several DACs of different types and price (eg Fiio BTR5-2021 and Qudelix 5K) but none of them offer the feature set of this device. I suppose the novelty is being able to see (usually) the cover art for the album being played plus enjoying very excellent rendition of the tracks which I know so very well. I do appreciate the inclusion of the 4.4mm BAL output as some of my headphones are terminated thus. The LDAC and aptX Adaptive BT codecs are a welcome addition as my phones have these features in common. The operating range is adequate for wandering around the house - downstairs. It is definitely on the chunky side but the features outweigh this aspect - dual outputs, long battery life, VERY decent UI and plenty of output power for any of my IEMs. Knowing my headphones well, my impression is the W4 does not noticeably colour the sound, remaining pretty neutral, yet with very decent impact. The only minor annoyance is having to 'OK' the volume level increase every time due to the warning message which pops up every time that I use it - this should be set to 'disabled' by the user if it is their choice!! One nice touch is the ability to connect to a cellphone without drawing any power from the phone - a switch enables use of the internal W4 battery only. Basic EQ settings are OK but sadly, the Hiby MSEB EQ machine is not included. Quite honestly - I'm really delighted with this device. Great value for money - might have paid more even and still been happy!

One of the unique features of this DAC is the optional screw‑on magnetic backplate. Isn’t that accessory available in your webshop?

Linsoul Audio

Hi! The screw‑on magnetic backplate for the HiBy W4 is not sold separately, it only comes included with the DAC itself.
