dbbeats earbuds use heart-rate data to adapt sleep audio in real time

The For Me Buds 2 combine a slimmer design, active noise cancellation and on-device biometric processing, with Kickstarter pledges starting at $99.

dbbeats is trying to move sleep earbuds beyond simple playback and masking, with a second-generation For Me Buds model that aims to react to the sleeper in real time. The company, which says it was spun out of LG Electronics in 2024, is positioning the new version as a more private, more comfortable and more responsive take on a crowded category that already includes rings, watches and other overnight trackers.

The latest design is notably slimmer than the first generation. dbbeats says each earbud is 10.4mm thick and weighs less than 4g, with soft ear tips and wing tips intended to ease the pressure that side sleepers often feel when lying on a pillow. That lower-profile shape is central to the update, as the company appears to have focused on one of the most common complaints about sleeping in earbuds: bulk.

Noise control is also more ambitious than basic sound masking. According to dbbeats and coverage of the launch, the For Me Buds 2 combine hybrid active noise cancellation rated at up to 35dB with passive isolation from the in-ear seal and adaptive masking to help suppress outside noise such as traffic, household sounds or snoring. That makes them more technologically aggressive than some rivals in the sleep-audio niche, including Ozlo’s Sleepbuds 2, which rely on masking rather than active cancellation and retail at a higher price.

The most distinctive element, however, is the way the earbuds handle biometric data. dbbeats says a built-in PPG sensor monitors heart rhythm through the night, while locally processed algorithms use that information to adjust audio on the fly. The company says the core sleep functions are handled on-device rather than on its servers, and that users do not need to create an account to access them. That privacy-first pitch may matter to buyers increasingly wary of how intimate health data is stored and processed.

In the morning, the companion app provides a summary of sleep stages, total sleep time, snoring events, heart rate and heart rate variability. dbbeats has also added an AI Sleep Chat feature, which lets users query their own sleep data in plain language. The product has been launched on Kickstarter, where it passed its modest US$5,000 target within a day, with Super Early Bird pledges starting at $99 and an expected retail price of $199. The company says mass production is planned for December, though, as with any crowdfunding campaign, backers are still taking on the usual delivery risk.

What gives the launch additional context is the way it reflects a broader shift in sleep technology. Many devices now measure sleep after the fact, but dbbeats is aiming to intervene during the night itself, using local processing to alter what the wearer hears while they are still asleep. If the company delivers on its claims, the For Me Buds 2 could appeal to light sleepers who want something more sophisticated than a white noise machine and less intrusive than a full-fledged sleep monitor.
