The digital voice recorder pen is crafted with metal alloy using CNC manufacturing and baking lacquer electric transition processes, ensuring durability, oxidation resistance, and scratch resistance. It features simple operation with a blind recording function and a ball pen-type mechanical bounce switch—press to start recording (pen cover lowered) and press again to end and save (pen cover raised). This multipurpose device allows simultaneous writing and recording, supporting two-way recording. The pen refill can also be replaced for use as a signature pen. Equipped with an acoustic 8-core DSP noise reduction module, it effectively reduces environmental noise. The recorder supports connection via an OTG adapter for phone management and file transfer, compatible with Android. For iOS devices, it offers plug-and-play convenience. Additionally, when plugged into headphones, it can play music and recordings, supporting line control for switching songs, fast forward/backward, volume adjustment, and file confirmation or deletion.
