An earbud case that recharges the phone that plays through it.
A closer look at the aluminium case, power reserve and design decisions behind Mifo Gen 4.
Mifo Gen 4 · reverse-charging aluminium case · IPX7
A charging case can do more than store earbuds. Gen 4 combines a 2600 mAh reserve with an aluminium enclosure and a reverse-charging connection for compatible devices.
The brief
Flagship audio without a royalty stack. Own the industrial design, the antenna layout, the case power architecture and the shell geometry.
The bet
Put 2600 mAh in a machined aluminium case so reverse charging is not a gimmick but a daily behaviour.
