For Riccardo Robecchi at Soundphile Review, the HIDIZS AP80 PRO MAX continues a tradition that has become increasingly unusual: making a capable digital audio player genuinely small. His Pure Copper Edition brings a distinctive material to the familiar concept, but the bigger story is how much functionality HIDIZS fits into a device that remains exceptionally pocketable.
Small Enough to Be Refreshing
Measuring 82.8 × 51 × 15.5mm, the AP80 PRO MAX is extremely portable. Riccardo finds this a clear advantage at a time when devices keep getting larger. His version uses a single block of pure copper, with glass covering the front and back and a diamond pattern beneath the rear panel.
The 2.95-inch screen is larger than previous AP80 iterations and remains crisp, bright, and readable even outdoors. Physical controls include dedicated playback buttons and a side volume wheel, while 3.5mm, 4.4mm, USB-C, and microSD connections keep the layout practical.
HiByOS Feels Better Than Before
The operating system is one of the areas where Soundphile Review sees meaningful progress. Riccardo describes HiByOS as simple, highly reactive, surprisingly smooth, and more responsive than earlier generations.
Its music settings provide extensive customization, covering equalization, gain, playback behavior, soundstage adjustment, and other options. The player can organize music stored on microSD cards up to 2TB or browse files directly.
Wi-Fi adds Tidal and Qobuz streaming, while Bluetooth is bidirectional and supports codecs including LDAC. DLNA, HiByLink, AirPlay, wireless file transfer, and bidirectional USB DAC functionality further broaden the ways the player can fit into different setups.
Neutral Sound Lets Earphones Speak
Riccardo considers the AP80 PRO MAX perfectly neutral, which he treats as a positive quality. With suitable low-impedance earphones and headphones, he hears no meaningful coloration compared with other solid-state sources.
The presentation is detailed, with decently fast transients, making the player a capable partner for IEMs and easier-to-drive headphones. Rather than adding its own strong sonic personality, it focuses on delivering the connected equipment cleanly.
A Compact Player Packed With Options
Soundphile Review particularly appreciates how the AP80 PRO MAX combines its small footprint with features normally associated with larger devices. The bigger screen improves usability, Wi-Fi expands streaming possibilities, and the updated software creates a smoother everyday experience.
Overall Assessment
Soundphile Review rates the HIDIZS AP80 PRO MAX 8/10 and considers it a valid, enjoyable little player whose strengths comfortably outweigh its limitations. Its excellent portability, strong build quality, crisp display, intuitive operating system, extensive settings, wireless connectivity, neutral presentation, and broad feature set make it a solid and genuinely practical all-around portable listening experience for everyday use. For Riccardo, it is refreshing to see HIDIZS continue betting on compact players: in this case, good things genuinely do come in small packages.
