80GB MP3 Player with Bluetooth and WiFi - 4.0ft Touch Music Player

In this review of the Oilsky M303 Pro the bottom line is simple: this is a portable player for people who want a dedicated offline device that also handles streaming apps. The reviewer found it most useful for long trips and exercise because it blends a large onboard library, expandability and native app support into a compact player. The 4.0' IPS touch screen and HiFi audio module make local lossless playback and video viewing surprisingly capable for a non-phone device, and its long battery life keeps music going for many hours.

Key Features

• Streaming apps built in: Preloaded access to popular music and audiobook apps gives direct online listening without relying on a phone.
• HiFi audio module: A professional noise reduction chip and support for lossless formats deliver clear, full sound for critical listening.
• 4.0' IPS touch screen: The 480 x 800 display supports 720p and 1080p video playback for a better on-device viewing experience.
• Large storage and expandability: Built-in memory plus a supplied 64GB card and a microSD slot that supports up to 512GB lets you carry vast music and video collections.
• Bluetooth and dual-band WiFi: Bluetooth pairing and 2.4/5 GHz WiFi make streaming, app downloads and wireless headphone use straightforward.
• Long battery life: The 2000mAh battery and low-power design enable very long music playback times for travel and exercise.

Who It's For

The Oilsky M303 Pro is aimed at users who prefer a dedicated media player for workouts, commutes and travel, and who value offline storage together with streaming app access. Fans of lossless audio and those who want a small device to complement a phone will appreciate the HiFi module, app compatibility and expandable storage.

This is less appropriate for those who need the latest mobile OS features or a large touchscreen smartphone replacement; the device runs Android in a player-focused form and does not replace a phone for calls or the full app ecosystem. Audiophiles seeking desktop-class DAC performance should also compare dedicated HiRes players.
