In June 2013, Microsoft released a new model of the Xbox 360 game console, the Xbox 360 E. This new model differs from previous Xbox 360 models in a way that will affect the way your headset is connected to the Xbox 360 E console.

Unlike previous Xbox 360 models, the Xbox 360 E does not have a S/PDIF (digital optical) output, which is necessary for connecting Turtle Beach surround sound products. To fix this, Turtle Beach has developed the Ear Force HD Audio Converter (HDAC), which is an HDMI to HDMI and optical converter that will let you connect a digital optical cable to the Xbox 360 E. This converter will include an HDMI cable to make it simple to connect your new Xbox 360 E to your TV and your Turtle Beach headset.

NOTE: In the chart above, for headsets marked as requiring a 3.5 mm Male to RCA Splitter Cable, this additional cable is only required if you want to get game audio in both your headset and your TV without having to physically unplug the Xbox 360 A/V cable from your transmitter. If you want audio in only your headset but not the TV, no additional cables are required; just connect the Xbox 360 E's A/V cable to the transmitter as shown in our Xbox 360 E setup YouTube video: click here
