The new co-branded Ozlo Sleepbuds come with a free year of Calm

The Ozlo Sleepbuds, one of the most premium sleep earbuds around, is expanding their lineup.

As of Nov. 13, the brand has teamed up with Calm, the company behind the popular sleep and mediation app. The result? The new Ozlo x Calm Sleepbuds, which comes in a new calm blue colorway and with a big perk: a free year of either a Calm Premium or Calm Sleep subscription (which are valued at $80 and $70, respectively). The sleep earbuds retail for $349, the same price as the original Ozlo Sleepbuds at full price.

At $349, the Ozlo Sleepbuds are one of the most expensive sleep earbuds on the market. Because of their higher price point, we don't currently recommend them unless you can find them on sale for less. (At the time of writing, the original Ozlo Sleepbuds are on sale for $299, but don't come with the Calm subscription). With that said, the more affordable sleep earbuds on the market don't currently have any existing partnership with a mindfulness and sleep company like Ozlo, meaning that these might be the perfect choice for someone interested in trying both sleep earbuds and a Calm subscription.

If you were to subtract the cost of the Calm Sleep subscription, the Ozlo Sleepbuds come out to $279, which puts them in a closer range to the $229.99 Anker Soundcore Sleep A30 earbuds (though the latter option does come with ANC). The Ozlo Sleepbuds are also available to purchase with an HSA or FSA.

Which Calm subscription you get depends on which device you plan on using with the Ozlo Sleepbuds. iOS users will have access to the Calm Sleep app, which is not currently supported for Android devices. As such, Android users will have access to the Calm Premium app. As for the main difference between the apps, the Calm Sleep's Apple App Store description notes the app provides "deeper, more personalized sleep support" over the more general Calm app.

The Ozlo Sleepbuds also come with their own dedicated companion app, which can be used to set alarms, listen to sleep sounds, or stream your own audio — like the Calm app library.

In the press release for this collaboration, Calm's chief content officer, Greg Justice, spoke of the compatibility between the two brands: "“Put simply: sleep is a superpower. By combining Calm’s trusted content library with Ozlo’s best-in-class sleep tech, we’re enabling people to fall (and stay) asleep more easily, ensuring they wake up refreshed and ready to own the day.”

 In addition to the blue colorway, the case for this collaboration features an engraved Calm logo and the brand's signature phrase, "Take a Deep Breath."
