• UHF Wireless Microphone: UHF has a longer range and better propagation outdoors and through solid objects like a human body
• The wireless microphone system adopts UHF ISM global unlimited frequency band transmission
• The wireless microphone system can automatically scan channels and pair them within 3 seconds
• It can obtain a stable, anti-interference, and adjustment-free transmission of strong signals with an audio range of up to 50m (164ft). No lag and signal loss
• SK750 wireless lavalier microphone is compatible with DSLR, Camcorder, Smartphone, for iPhone (Lightning adapter and Type-C adapter not included)
• The wireless microphone system is widely used for YouTube Live-stream, Vlog recording, interviews, program hosting, podcast, presentation, church, weddings, etc. No app and driver are needed
