Zinc alloy USB MP3 player and voice recorder with 35-hour battery life and professional HD recording

This compact USB device merges the functionality of a professional voice recorder with a portable MP3 player in a durable zinc alloy housing. Measuring just 85mm by 26mm by 11mm and weighing 55g, it is designed for discreet, on-the-go use in various settings. The recorder features the ATJ2127 professional recording chip, enabling high-definition recording at 48kHz sample rates in both WAV and MP3 formats. With a substantial 410mAh built-in lithium battery providing approximately 35 hours of recording time or 21 hours of music playback, it supports extended sessions without frequent recharging. The device connects via USB 2.0 for fast file transfer and is compatible with Windows 2000 and later operating systems.
Features and Construction

The recorder's construction focuses on durability and clear audio capture, with several features aimed at practical recording scenarios.
Material and Build
The zinc alloy shell offers a robust exterior that helps protect the internal components from impacts during daily use. This material choice contributes to the device's 55g weight while maintaining structural integrity. Internally, the professional ATJ2127 recording chip processes audio, supporting recording formats of WAV and MP3 with a signal-to-noise ratio of 80dB. The built-in 18mm by 26mm speaker delivers 1W of power at 8 ohms for direct external playback, while a 3.5mm dual-track headphone jack provides private listening options.
Size and Practical Fit
With dimensions of 85mm in length, 26mm in width, and 11mm in thickness, the recorder has a slender profile that fits comfortably in pockets or bags. The 96x64 dot screen LCD with LED backlight ensures readability in various lighting conditions without being obtrusive. The compact form factor does not compromise on functionality, housing the 410mAh lithium battery that enables the extended 35-hour recording duration. The USB 2.0 connector is integrated for straightforward connection to computers for file management.
Uses and Placement

This device serves multiple roles, from professional recording to personal media playback, suitable for different environments.
Event or Professional Use
For meetings, lectures, or interviews, the voice-activated recording (VOR) mode conserves storage by only recording when sound is detected. The timer recording function allows scheduling recordings to start at specific times, useful for timed events or automated capture. Real-time monitoring through the hearing aid function enables immediate audio feedback, while the AGC (Automatic Gain Control) adjusts microphone sensitivity to manage varying noise levels. Password protection on startup secures sensitive recordings, and files are automatically named with timestamps for organised retrieval.
Everyday Home Use
As an MP3 player, it supports WMA, WAV, MP3, and OGG audio formats, functioning as a personal media device for music or podcasts. The loop recording and A-B segment repeat features aid language learning or content review. The built-in speaker allows for shared listening without headphones, and the device operates within a 0°C to 40°C temperature range for indoor comfort. Checking remaining recording time helps manage storage across the available 8G, 16G, or 32G capacity options.
Benefits and Buying Value

The recorder offers tangible advantages through its dual functionality, battery efficiency, and protective features.
Reuse and Low Maintenance
The rechargeable lithium battery supports multiple cycles, reducing disposable battery waste. The zinc alloy shell's resistance to falls helps maintain device appearance and function over time. Automatic file saving during low battery detection prevents data loss, and the USB 2.0 interface facilitates easy file transfer and charging without specialised cables. The device's compatibility with common audio formats extends its usefulness across different media sources.
