Xbox One backwards compatibility

The E3 gaming convention in Los Angeles this week saw Microsoft announce that the Xbox One will now be backwards compatible with Xbox 360 games.

The feature is currently available in Beta, but will receive a general rollout in the Autumn. 

Digital games you own that are backwards compatible will show up in the “Ready to Install” section on the Xbox One. Supported disc-based games can be put into the console and installed to the hard drive, but the disc will need to be kept in the console to play it. 

Only 21 games are supported at the moment, but more will be added over time. A full list of games can be found on the Xbox website.

Binaural recording in-ear headphones

German manufacturer Binauric has taken to Kickstarter to seek funding for OpenEars. The in-ear headphones claim to record binaural, 3D audio, by having microphones built-in to the headphones. 

Binauric says the benefit of this is that it removes the need for a separate binaural microphone, which attempts to recreate the shape and density of the human head. By allowing users to place the microphones in the right spot for their hearing, they’ll record more lifelike sounds. That's the theory.

A HearThrough function allows users of the Bluetooth headphones to hear sounds around them, while still listening to music.

At the time of writing, the project has raised just under €50,000, of €125,000. You can pre-order a pair, with prices from €99.
