Wallet with iPhone 5 case – Danny P. Inc. These wallets let you keep your phone and your wallet in one place. Which is great, because I'm always patting my pockets to make sure I have both. Starting at $129, they have 4 colors.
You'll get a lot better sound from your computer with a USB DAC than a sound card. This one even has a optical input. I have the Music Streamer II but I could use the optical link. I'm using this TEAC UDH01B and it's amazingly clear and transparent.
