We’re back for another round of the very best deals on gear and gadgets in the Cult of Mac Store. This week, we’ve got an extra huge Bluetooth shower speaker, a simple but powerful mobile VPN, a handy app for cutting down on reading times, and a set of workout-ready Bluetooth earbuds. Everything in this week’s roundup is discounted by 75 percent or more, read on for more details:

Let me count the ways that I have killed so many successive sets of earbuds, whether from Apple or otherwise. Rain, sweat (ears), sweat (general, dripping), wet ear canals from insufficient after-shower toweling. More rain.

You get the idea.

If only I’d had a pair of Klipsch’s new rugged S4i earbuds, which are rubberized against both the elements and also my deadly perspiration.

The earbuds are also fully iReady, with a mic for calls and a three button remote for play/pause/answer and volume control. The specs say that the sensitivity (a good measure of how loud they are) is 110dB and the frequency response goes from 10Hz to 19kHz – a respectable range for a ‘bud.

But the toughness is the thing, and these multicolored cans can put up with most exercise and outdoor activity.

I doubt they can resist my single most common way to break a pair of headphones though – the Tug. The Tug can be achieved in many ways, but has one common element: you forget about a dangling cord and catch it fatally on an immovable object, or your own body. I have ended the life of a pair of Porta Pros by standing from a crouch and catching the cable on a knee. And I butchered a pair of retro Panasonic over-the-ear headphones when the cable snagged on a post in the street.

I should probably be more careful.

The S4is will be available soon.
