If you run or exercise outdoors, it's important to stay connected to your surroundings, even if you need a great playlist to keep you going. To balance your music and spatial awareness, traditional earbuds aren’t always ideal. That's where the Shokz OpenRun headphones come in. They use something called bone conduction technology which sends sound through your cheekbones, keeping you tuned in to both your music and whatever is happening around you.

And as of Feb. 6, you can get the Shokz OpenRun on sale for just $89.94 at Amazon. That's $40 off the list price. This discounted rate is available for the black and blue models.

They're robust and can cope with all kinds of runs. And with an IP67 waterproof and sweat resistance rating, these are ideal for running in the rain and intense gym sessions. They even have a moisture detection alert to keep charging safe for when they take on a little too much water.

The battery life will last up to eight hours on a single charge, and a quick 10-minute top-up gives you around 1.5 hours of listening. That's ideal when you don't have time for a full charge.

This is a limited-time deal at Amazon, so act fast to avoid missing out.
