Thank you for your post and Welcome to the Bose Community.
I am sorry to hear that you are having problems with your SoundLink Micro. This certainly sounds unusual.
Could you please check for and install any available product updates. You can do this by visiting btu.bose.com and follow the instruction to ensure your product has the latest feature and enhancements.
I would also like you to try using a different source device so that we can ensure if the issue is definitely from the speaker.
Get back to me once you have tried to two above steps, and if the problem persists, I will be more than happy to assist you further.

I tried to use another device (an iPad, I previously used an Android smartphone) but the issue still occurs; actually, it occurs even before the Bluetooth connection with the voice prompt, so it seems to be that it's not a Bluetooth related problems. On both Bose Connect App (iOS and Android), the product is up-to-date and no updates are available.
I also want to say that my micro-usb cable included in the box is defective. When I used the product for the first time, I tried to plug-in the included cable but I couldn't plug it in at all (it's as something is blocking) ; I also tried to plug it in into another micro-usb device but it also blocked, so this issue comes surely from the cable. But I really don't know why my first issue occurs because my product is new, I don't drop it and I don't put it in the water neither.
Thanks in advance for your response,
Oh okay! Thanks a lot for you reply @enthusiast !! I was very disappointed and dubious about that, I'm now a lot more reassured and I think I'll get use to it! 🙂
I was searching for a picture like this of the way this speaker is design for the entire day yesterday; but didn't find one.
Have a great day!
I'll mark your answer as "solution".
