In a statement, Bose said the new buds had improved noise masking and also new content which would help people relax.
"They combine a new acoustic and electronics design, a new enclosure that’s lighter than a dime, new proprietary ear tips for a secure, super-soft fit, and over 35 free tracks – all methodically produced and tested," the company said.
"The result is an engineering breakthrough: two tiny, ultra-comfortable, truly wireless buds that block, cover, and replace the audible distractions from loud partners, neighbours, dogs, and traffic – and reduce the mental distractions from long, busy days."
“You can’t duplicate the experience combining earbuds with apps, playing your music louder, or using earplugs and bedside machines, so millions of people are still suffering. We never gave up on helping them, and that’s why we’re so excited about Sleepbuds II.
"They ‘quiet’ more of the low frequencies found in the biggest threats to a peaceful bedroom - like snoring partners, idling engines, and nearby footsteps. And with new relaxation tracks, they help quiet your mind, too.”
The company said it carried out a study in association with the University of Colorado Anschutz Medical Campus and the UCHealth CARE Innovation Centre to test the impact of its sleep technology and claimed it had been clinically proven to help people fall asleep faster.
"The research also found that 100% of participants confirmed Bose noise masking worked against the common disturbances that kept them up or woke them up; 86% said the product helped them fall asleep easier; 76% said it helped them stay asleep, and 80% reported an overall improvement in sleep quality," it added.
The buds have an improved anodised aluminium case that stabilises each bud while stored and charged and provides up to 30 additional hours of battery life. They are compatible with both iOS and Android devices and are sweat- and water-resistant with an IPX4 rating.
The Sleepbuds II will sell for $379.95 in Australia and NZ$419.95 in New Zealand at select resellers. Pre-orders have been open since Wednesday.
