Dear Customer, If you have a empty micro SD card, we could help you to reduce the sound of that Announcement. Please go to https://docs.google.com/file/d/0By-_EtnCQsM5d0dKRm9XWmhSUlU/edit download the mp3 file at first. Then: 1. Copy the file named UPDATE_123UP.MP3 to an empty micro sd card. 2. Turn on the speaker, insert the micro SD card. The Bluetooth speaker will switch to TF card model and read the MP3 file. 3. After card being inserted, LED light will be off. It will be on again after the update (about 5-10 second) 。Please do not turn off the Bluetooth speaker in the process of update; otherwise you need to reset the Bluetooth speaker. 4. After update, turn on the speaker again. The announcement volume has been reduced. Note:If LED light does not turn on again. After 30 seconds of it being turned off, the Bluetooth speaker has already successfully updated. Thanks, DKnight,LLC

It will last 4-5 hours at maximum sound. But for normal usage, it should last for more than 8 hours. Thanks.

Yes you can, they recommend that it be fully charged but I used it straight out of the box while charging, no problem.

Dear Customer, It all depends on how large is the classroom. The sound should be loud enough to fill a normal classroom (around 30 students classroom).

Turn the speaker on first. Then turn on your phones Bluetooth and search for the "bigbox". Connect, the speacker will make a beeping noise and then u can play music.

Dear Jeffrey, When the speaker is charging, the Red LED light will be on. After the battery was fully charged, the LED light will be turned off. Thanks.

loud enough to listen in your bedroom or bathroom, NOT loud enough to use for a BBQ or generally anywhere outside unless quiet. Might be ok for camping etc.
