Sony will release its Xperia Ear Duo wireless earbuds in May for $279.99. Preorders for the “open ear” headset, which has been shown in concept form over the last two years, start today at Amazon.

The Ear Duo is basically the polar opposite of Sony’s esteemed noise-cancelling headphones; these earbuds aim to deliver a “dual listening” experience that combines your music with environmental sounds happening around you. Audio notifications pertaining to your calendar, news headlines, and other topics are also sent to the headset. Google Assistant and Siri integration is also built in, depending on whether you’ve got the Ear Duo paired to an Android or iOS device.
