A:AnswerNo this speaker does not keep looking to pair with devices. Although if you already have your bluetooth on and it is set as a recognized device the speaker will automatically connect.
A:AnswerHi, Arthur!
No, this Bluetooth speaker doesn't support USB function. You can only play music via Bluetooth connection through your smartphones.
Happy to help,
David
A:AnswerThe sound goes up pretty high. In the store they didn’t have the sample one out so you could try it and I was kind of nervous when I bought it because I didn’t know how high it would go. But I like how high the volume is.
A:AnswerHi anna2467, Yes, you can only charge this speaker using USB. For more information about charging, please refer to the link below. I hope it helps. Regards, ^Ron
