Product overview: BF1 is wireless audio transmission system with low latency (0.3ms) and professional sound quality, which can truly restore the timbre and detail of the instrument itself. As this product works on IoT frequency band, it avoids the current complex 2.4GHz signal environment and ensures the stable signal transmission. The transmission distance can be up to 30m. This product supports multiple receivers working in one channel at the same time, which further expands the receiving range and easily adjust to large venues. This product is simple and convenient to operate, can let new users quickly start. We also equip the transmitter/receiver with a large capacity quick-charging case to ensure that the product has enough battery life when using in various scenarios.
