Based on the picture and the below spec sheet. The charging cable for the FreeX is micro USB not USB C.
The Charge 4 is USB C. So if your going out of town with these you will need to bring 2 cables not just one.
If the earbuds are free, why does this bundle cost $20 more than the speaker by itself?
They’re not “free”. The earbuds are named “Free X”.
Still, interesting that they are still $20 more…
The bundle is cheaper, so I’m slightly confused by your confusion.
Bundle: $109.99 + tax.
Separately: $89.99 + $39.99 + tax.
