Ozlo's Sleepbuds 2: A Leap Forward in Sleep Technology

The latest iteration of the sleep earbuds startup's flagship product promises to revolutionize the way we sleep.

Ozlo's Sleepbuds 2 build on Bose's sleep earbud legacy, addressing the key areas of improvement that the original product lacked. The new model boasts 14 hours of battery life, a significant increase from the roughly 10 hours offered by the original Sleepbuds. The charging case can now store enough power for two to three nights of use per charge, and a button has been added to play a sleep sound or snooze the alarm without reaching for the phone.

One of the biggest complaints about the original Sleepbuds was Bluetooth connectivity, which could be flaky. Ozlo claims that the Sleepbuds 2 offer longer Bluetooth range, a more reliable connection, and dedicated pairing controls for faster setup. The improvements come from a redesigned antenna and extender, Ozlo said.

The audio system has also been updated with a built-in amplifier for better sound masking and improved sound quality. Personalized sound tuning is new, optimizing audio for specific use cases such as Spoken Word, Airplane mode, and Focus mode, in addition to a Balanced mode.

Another new feature is a Sleep Shield, which will block incoming calls, alerts, notifications, and Bluetooth audio streaming. This works if the users hasn't already enable their phone's built-in sleep focus mode.

Ozlo's sleep insights have expanded to include more details around sleep patterns. The biometrics in the buds monitor breathing and movement, while the case monitors room conditions, such as the sound levels, light, and temperature. This can help wearers learn which sleep environments lead to deeper, more restorative sleep, helping them improve their sleep over time.

The company outlined its plans to become a broader platform for sleep data during an interview with TechCrunch at the Consumer Electronics Show in January, including plans to use AI for better interpret users' sleep patterns. It is also developing an AI 'sleep buddy' that would allow users to chat with about their sleep data.

To kick off the launch, Ozlo is offering a sleep mask and travel case with each purchase for a limited time. The $279 Sleepbuds 2 also ship with four pairs of silicone ear tips in different sizes, the charging case, and a USB-C cable.

As an existing Sleepbuds owner, I'm looking forward to trying the new Sleepbuds 2 to see if they're worth the upgrade. The addition of personalized sound tuning and the Sleep Shield feature are particularly exciting, as they address two of the main areas where the original Sleepbuds fell short.

When it comes to sleep technology, Ozlo's Sleepbuds 2 are certainly a step in the right direction. With their improved battery life, connectivity, and sound quality, they have the potential to revolutionize the way we sleep. As the sleep technology landscape continues to evolve, it will be exciting to see how Ozlo's Sleepbuds 2 stack up against the competition.
