I’m quite sure I haven’t seen more useful cellphone strap than this one. The simple strap is basically an adapter which connects to your Nokia or Sony Ericsson phone to allow you to use any universal 3.5mm earphones. Simply attach it to your Nokia’s pop-port or Sony Ericsson’s fast port, connect any standard headset and you’re ready to go. Now the adapter is always with you, no matter where you are and that convenience costs only $9 plus shipping.
It’s easy as that. Here are the links to Nokia and Sony Ericsson adapter handy straps. That’s on Hong Kong-based Brando’s web store.
