  • 35W output reaches about 120 listeners clearly

Wireless Voice Amplifier 35W

The BFKK wireless voice amplifier delivers 35W output so about 120 listeners hear clear, distortion-free sound. A 2000mAh rechargeable battery runs 8-10 hours and recharges in 3-5 hours. Compact dimensions of 3.4 x 4.6 x 1.5 inches and a weight of 0.6 lb make it easy to carry for teachers, trainers and coaches.

Suitable users and limits

Works well for classroom teaching, guided tours, fitness instruction and meetings where a single amplified voice is needed. Not suited for users who need a second wireless microphone, Bluetooth streaming from two sources simultaneously, or a unit that can be mounted on a standard speaker stand.

Battery runtime decides fit

The built-in 2000mAh lithium cell provides 8-10 hours of continuous use per charge, which determines whether the amplifier lasts through a full day of classes or back-to-back sessions.

Questions about this item

Does the 35 W speaker need any extra power source to run?

No, the built-in 2000 mAh rechargeable battery powers the unit for 8 to 10 hours and recharges in 3 to 5 hours.

Will the wired headset microphone still work if I pair a Bluetooth audio source?

Yes, the wired headset and Bluetooth playback operate simultaneously so you can speak over streamed music.

How can I confirm the 35 W output is reaching the full 120-listener range after setup?

Walk to the back of the room; if speech stays clear and distortion-free at that distance the amplifier is performing as specified.
