Today, Bose announced the availability of its first ever noise-masking sleepbuds—tiny, wireless earbuds that are designed to block, cover, and replace the most common noises that interfere with sleep.

Bose sleepbuds are the smallest Bose product ever made. They come with 10 pre-loaded “sleeptracks” that mirror the frequencies of snoring, neighbors, dogs, traffic, and more, according to the company. They feature new patented ear tips for a snug, soft fit, and can run for up to 16 hours.

Bose sleepbuds are the first Bose product to use Bose noise-masking technology. They aren’t active noise cancelling headphones, they’re not in-ear headphones with an added feature, and they don’t stream music; according to Bose, “every last detail was optimized for one thing—better sleep, all night, every night.”

“Noise-masking is a science,” says Daniel Lee, systems engineer for Bose sleepbuds, in a release. “It’s more than ambient sound or white noise. You can’t achieve it by simply turning up the volume on calming songs. And depending on the situation, it’s more effective than active noise cancelling—even ours. During the day, QuietComfort headphones improve focus and productivity, or let you hear your playlists and calls clearly in loud places. But at night, you’re trying to shut down completely, and the world is naturally more quiet—and when it’s quiet, even the slightest sound seems loud. Bedside machines can’t cover it, earplugs can’t block it, and earbuds meant for sitting, standing, or moving can’t be worn for hours laying down—especially on your side. But Bose sleepbuds can. And if you’re someone who’s tried everything and nothing’s worked, or haven’t tried anything believing nothing will, we made them for you.”

Brian Mulcahey, category director of Wellness at Bose, says, “Sleep deprivation is a growing, global epidemic that impacts our lives and our health. It hits close to home for us, too. For years, our customers, coworkers, friends, and family members have asked us to make a product that helps them fall asleep and stay asleep. We took that seriously, and put together an incredible team of experts in noise management, acoustics, psychoacoustics, electronic miniaturization, wireless in-ear headphones, and neurology. They represent some of the top talent in their fields, and their work inspired our entire company. Because behind the staggering statistics are real people, and this product can be a game changer for many of them.”

Each bud weighs just 1.4 grams, and measures just over 1 cm wide and high. On their exterior is a laser-etched antenna for reliable connectivity to a phone or tablet. Inside, there’s a rechargeable silver-zinc battery, a mini transducer, and a micro-circuit board with flash memory to store the preloaded noise-masking sound files. Both attach to a new noise-isolating StayHear+ Sleep tip (which creates a physical barrier to unwanted sound). StayHear+ Sleep tips are included in three sizes. They’re soft, pliable, and virtually weightless. And their materials, shape and form were optimized specifically for rest, so they feel great and stay in all night, regardless of sleep position.

Bose sleepbuds use low-energy Bluetooth, are iOS and Android compatible, and come with the Bose Sleep app that allows users to update, control, and select preferences. Users can set an alarm for the morning and choose the sleeptrack and volume that works best for their environment.

Bose sleepbuds come in a brushed aluminum charging case that provides up to 16 hours of battery life unplugged.

Bose sleepbuds have a high-gloss white finish and will retail for $249. They’re available in the US and Canada beginning June 21, 2018.

Sleepbuds prototypes were introduced in November 2017 on Indiegogo, and sold-out in 6days. Non-production units were sent to owners in March 2018, who provided feedback on their performance so improvements could be made to final production units—which all Indiegogo customers will receive as a free replacement.
