When clapping my hands next to my ears, I could hear the QuietOn’s noise ANC momentarily reduce the volume of the racket. With the earbuds in, I repeated the same test and there was an immediate, dramatic reduction in ear-ringing volume while performing the same vigorous clanging. The resulting gong was loud enough to cause auditory pain and a bit of ringing in my ears (I know, my doctor would scold me, but was for the sake of science, right?). Without the QuietOn earbuds, I gave a kitchen skillet a healthy whack with a metal spatula, about 12-inches from my skull. I noticed a large difference in my spatial ability to determine the source and direction of sounds, but in a noisy environment, my hearing is more important to me than knowing precisely where a sound came from. “Hearing” mode allows sound to pass through the microphones and into the wearer’s ears, at similar levels to my normal hearing, but with one huge difference (read on, intrepid Gadgeteer…). The button’s sole purpose is to toggle the earbuds between “hearing” and “silent” modes. Each earbud has a single, itty-bitty button between the charging contacts. Three pairs are included for comfort and sound isolation.Īdjacent to the “L” and “R” labels on each earbud are tiny microphone holes. The earbuds turn on as soon as they are removed from the charging case. Ear-tips change with a twist and are securely attached. There are no volume controls, nothing needs to be paired, and there are no configurations except for installing the correct size ear-tips to fit your ear holes. The earbuds are amazingly easy to operate. Some sound bypasses the ANC through “sound leaks,” bone conduction, and other factors, but the results are quite effective. The sound and corresponding electronic signals effectively cancel each other out, reducing the volume of the ambient audio. ![]() ![]() Then, circuitry produces audio of equal but opposite magnitude through the accompanying speaker. The technology that makes Active Noise Cancelling (ANC) products work is fascinating. The earbuds are minuscule at about 0.72 x. Inside the case are springy contacts that engage the charging pads on each earbud.īright blue LEDs illuminate to indicate charging is in progress. The case is tiny, about 2.36 x 0.96 inches (6 x 2.5cm). Stickers protect the battery contacts on the earbuds during transport from Finland. A power supply is not included, but any handy USB socket you have available will do the job, charging the case and earbuds in about an hour.
