HIDIZS AP80 PRO MAX Red / Green All-in-One Streaming HIFI Music MP3 Player Hi-Res Audio Bluetooth 5.1 Dual ES9219C USB DAC MQA

Features
The AP80 PRO MAX is a feature-rich DAP for its small size. It uses a Linux-based Hiby operating system, Hiby OS, which is one of the best operating systems that I have tried in non-Android-based DAPs.

It features a full-metal chassis and utilizes Ingenic 1600E SOC processors, which are fast when used in a DAP. The DAC chip used is the ESS SABRE ES9219C x 2, which I heard on other devices and liked the sound of.

It also supports up to 2TB of MicroSD card capacity, allowing for direct music playback from local files. Additionally, it can stream music over a 2.4GHz WiFi connection via Tidal and Qobuz.

The AP80 PRO MAX can also be configured as a digital source for an external DAC amplifier and as a DAC amplifier for digital sources, such as phones, laptops, and PCs, via the USB-C connection.

AP80 PRO MAX is highly versatile in its use, as it can also function as a Bluetooth 5.1 audio transmitter or receiver. It can be connected to a DLNA and AirPlay WiFi network, and also allows wireless music transfers via the WiFi connection.

The 3.5mm output is 75mW at 32Ω, and the 4.4mm output is 125mW at 32Ω. The Dimensions are 82.8*51*15.5mm, and it weighs 81g.

Luxury Exquisite Design Meets Effortless Control

The AP80 PRO MAX features a 2.95-inch 480×640 HD touchscreen with a golden aspect ratio, delivering a crystal-clear display while ensuring a comfortable, ergonomic grip. Its aluminum alloy frame and dual-sided glass panels exude a sleek, premium look that’s both durable and elegant.
The newly designed volume wheel offers a smooth, intuitive feel, while three physical buttons ensure quick track switching for any listening moment—whether it’s a calm evening or an intense workout. Every detail is crafted for an exceptional audio journey.
