QUIETON 3.1 SLEEP EARBUDS

£249 (APPROX. $316) QUIETON.COM

If standard foam earplugs don’t block out the world and allow you to have a good night’s sleep, the QuietOn 3.1 sleep buds might be your solution to snoozing. The technology inside these compact earbuds uses active noise cancellation that automatically generates opposing sound waves as it detects ambient sound. The two sound waves collide, nullifying their vibrations and cancelling each other out, leaving you oblivious to any surrounding noise.
