Get the best of both worlds with 46 percent off these noise-cancelling Beats Solo Headphones

Give yourself a little privacy, or let in the world, with these high-tech headphones.

We’ve spent a long time trying to tune out the world. The first noise-cancelling patent was filed all the way back in 1936, and started entering industrial use on airliners in the 1980s, with pilots being issued noise-cancelling headsets. And now, anybody can tune out the world, if they want to, with Beats Solo Pro Wireless Noise-Cancelling On-Ear Headphones, currently $159.99, 46 percent off the MSRP.

Noise-cancelling, also known as active noise control (ANC), uses physics as a filter. Every sound is a pressure wave, with peaks and troughs. ANC generates precisely the opposite wave, so the peaks are collapsed by a trough under them, and vice versa. As a result, you may feel the sound pressure, but you won’t hear anything.

The Beats Solo offer two modes. Either you can leave the ANC on, and enjoy just your personal mixes and podcasts without the world intruding, which is perfect for relaxing or tuning out the office, or you can enter Transparency mode, and lay your soundtrack over the world instead, ideal for situations where you might need to hear what’s going on around you.

Beyond that, Beats come with a host of handy design features, such as turning off when you fold them up, a one-button design that makes answering calls and skipping tracks simple, and wireless audio sharing that uses Bluetooth 1 to connect to others pairs of beats, making it easy to share what you’re hearing with friends. It’s all supported by a battery that can last up to 22 hours, and gets three hours of playback on a ten-minute charge.

Finally, they’re designed for maximum comfort, in your home and on the go, so you never have to stop listening. At $159.99, 46 percent off, the Beats Solo Headphones give you a little more control of what you hear, no matter where you are.
