ZANSONG K31
ZANSONG K31 WIRELESS LAVALIER MICROPHONE
PERFECT 360° AUDIO PICKUP – LATENCY <20MS – CONVENIENT SIMULTANEOUS RECORDING & CHARGING
1. VISUAL CHALLENGES & THE SOLUTION FROM ZANSONG VOICE
A lavalier microphone may seem small, but it directly determines the quality of a content creation video, an online lecture, or an e-commerce livestream session. Just a one-second delay causing audio lip-sync misalignment, harsh crackling ambient noise, or a phone running out of power mid-stream will render all scripting efforts meaningless.
Part of the ZANSONG VOICE product line, the ZANSONG K31 Wireless Lavalier Microphone is specially designed for vloggers, content creators, and livestream hosts. Featuring a dual transmitter setup (2 collar clips), proprietary 2.4G compression algorithm, ultra-low latency under 20ms, and smart simultaneous recording and charging, the ZANSONG K31 delivers clear, smooth sound that stays perfectly in sync across every frame.
2. KEY HIGHLIGHTS OF THE ZANSONG K31
