The N505 is an ultra-compact portable AI voice recorder built for meetings, lectures, interviews, legal evidence collection and daily note-taking. Equipped with Bluetooth 5.3 and dual-band WiFi, it delivers seamless wireless linkage with mobile devices.

Adopting dual silicon microphones, it captures crisp, noise-reduced audio and stores files in standard MP3 format with built-in 4GB SD NAND memory. Supporting 12 hours non-stop recording and 1-year ultra-long standby via the 135mAh battery, it adopts wireless charging for cable-free convenient power supply.

Its highlight lies in full-stack AI productivity functions: original audio recording, automatic speech-to-text transcription, intelligent content summary, and one-click mind map generation to organize your audio notes efficiently.

Measuring only Ø32.3*8.6mm and weighing around 10.6g, the tiny round body supports three wearing forms: pendant lanyard, watch-style wrist strap, and clip-on collar clip, fully adapting to multi-scene recording demands.

Suitable for business negotiations, university courses, media interviews, legal evidence collection, daily inspiration recording and corporate training. The 3-color LED light and independent recording/power buttons bring simple, intuitive operation for all users.
