The battery life was great for a full day of teaching and reduces the strain possible with teaching all day. USB charging cable was super easy to use too. The volume level is is easy to adjust to the size of the room from the headset and from the speaker itself. This has been a tremendous asset in my classroom. ### ⭐⭐⭐⭐⭐ Bluetooth Voice Amplifier really works *by C***Y on Reviewed in Canada on 6 July 2022* We purchased this for our Safety Coordinator to do his Tool Talks - people said they couldn't hear him so this definitely has made his life a lot easier.The team liked it so much they have purchased a second set to be used for yard talks.
