Spectacles, testicles, wallet and watch.
Not included in that old expression about things a man can’t leave without? Keys and phone.
Rather than fuss with the phrasing, let's consider the KeySmart Pro with Tile, a stainless steel organizer that allows you to easily locate your keys using your smartphone and vice versa.
Implanted with a Tile tracker, the Bluetooth-enabled KeySmart can always be located using an app on your phone that will pull up a detailed GPS map displaying the organizer's location. If you have your keys but are a missing phone, just hit a button to make it ring, even on silent.

Besides that, the KeySmart’s pocket-friendly design can hold up to 10 keys at once and the device is also equipped with an LED flashlight, bottle opener and a micro-USB charging port.
Starting at $54 but available for less in bulk orders, the KeySmart Pro should ship this month.
If you're a loser (of stuff), it could be a key purchase.
