Some of us would like to keep our eardrums in working order. To do that you can avoid concerts and the like and it also helps to have a pair of earplugs handy, but it’s not always convenient to carry them around. Unless you could fit them in your wallet somehow, like these RNID plugs from designer Shing Lo.

They even come with a set of rubber gaskets for a tight seal in your ears. Plus you can put them back on the card for storage. If these ever show up in the market, they would be pretty popular as a disposable and convenient product.

These are some excellent renders, but unfortunately this is just a concept Sony Cybershot camera called ‘Snap’. It was obviously inspired by a man’s wallet, the surface is even covered in leather. Like some other ultra compact Cybershot cameras, you slide the cover to activate, only it pivots from a corner for easy one handed operation. But aside from that, it’s just another typical Cybershot.

Some users would really love the compact design as you won’t stand out as an obvious tourist while using it, while you take pictures inconspicuously. Others might find it a bit too fragile and wouldn’t be able to resist the urge to actually put it in their back pocket and break it.
