Phone cases that double as a wallet aren’t a new idea. But they seem to always be designed for the iPhone. The CM4 Q Card Case is unique because it’s been made for the Samsung Galaxy S4. This case features a plastic shell with a fabric pocket that can hold up to 3 credit cards. The interesting features don’t stop there though. This case also has a special non-powered sound amplifier built into it. See that small bulge on the bottom left edge? That’s what CM4 calls the Direct Channel Audio. It funnels the sound from the speaker forward to boost volume. The Q Card case is available in 4 colors and is priced at $39.99.
