Strictly speaking, we shouldn’t call the cell phone charm mini speaker, because there is no speaker unit in it, but the phone charm can make anything play music.
Just as we see, it’s a spherical cell phone charm featuring bright color, of course, it’s not the most bright feature. The spherical phone charm can be separated into two parts. One of parts comes with standard 3.5mm audio jack. Once you connect your iPhone or any audio device with 3.5mm jack with the hemisphere, and put it on any flat surface, the hemisphere will turn into a genuine mini speaker.
The candy mini speaker cell phone charm is available in six colors, including black, blue, green, orange, pink, and white. Each one costs $22 USD. If you like the cute cell phone charm integrated mini speaker, jump to StrapyaWorld for more details.
