Beats Studio 1.0 with AAA batteries newly installed, doesn't turn on

It was years ago until I just remembered that I should be looking for a solution to this issue. So, basically, this 1st gen Beats Studio is my daily headphones for all sorts of stuffs.

Until one day, during my college life, even if putting on fresh AAA batteries, it doesn't turn on.

I didn't want to meddle too much into it and I was just hoping to find an online troubleshooting guide. I can repair phones but I couldn't repair audio tech though.

Anyone had a solution for this power issue with the First Gen Beats Studio? The switch doesn't turn on, no amber light, nothing despite having a new set of batteries in it.
