Microsoft has posted what appears to be the Xbox Series X's boot-up sound. If it sounds familiar, that's because it's the same startup sound that was featured in an Xbox video from May.

Microsoft shared the new Xbox sound using Twitter's new voice notes feature. It's a calming noise, and it's quite different--and much longer--than the regular Xbox One's boot-up sound. In a follow-up tweet, the Xbox account said of the startup sound, "It's like a choir of gaming angels singing in your ears."

The Xbox Series X is scheduled for release this holiday. There are a number of key particulars about the console still to be unveiled, perhaps the biggest of which is its price. Here at GameSpot, we predicted what we think the console will cost, but Microsoft has yet to make an official announcement.
