Ridges In Audio Jack
I bet this is another thing you never really knew the meaning of, but just accepted it. They aren’t just so the jack doesn’t fall out of the port, but actually, the material making up the ridges is used to protect and keep the wires in place so they don’t break while you’re listening to music. They also dictate which headphone all of the music goes to! One band is for the left headphone, one for the right, and one for both.
Silica Gel Packets
Usually, we see these packets inside of a shoebox or a brand new purse, and we know that they’re meant to keep the item you’ve purchased clean and fresh until you start to use it. Have you ever really thought about what’s inside of these packets, though? The stuff inside is called a “desiccant”, which means that it helps to keep moisture out; actually, these little packets can absorb humidity from their environment up to 50 percent! This can be super useful if you drop your phone in water. Ditch the rice buckets and grab onto the silica gel packets.
