The Boya BY-V1 for iOS is a wireless microphone for iPhone models and iPad models. Connect the receiver to your phone or tablet via the Lightning port and get started right away. With this microphone, you can easily record a long vlog without recharging. That's because the battery lasts 9.5 hours. Is your phone almost empty? Connect a Lightning charger to the receiver, so you can charge your phone and record sound at the same time. The microphone has a tie clip. You can attach it to a clothing item with this, like the collar of your blouse. You can record sound more closely to the audio source that way, making voices sound clear.
