I bought this item to use with the Sennheiser GAME ONE, Open Acoustic gaming headset - black
and my XBOX ONE. Setup was simple and involved attaching the console to the mixamp with the provided optical toslink cable and usb cable which were both very long. Finally the headset needed to be plugged into the provided Y adaptor and a couple of settings changed/confirmed on the console.
I was vey impressed by both the quality of the product and it's packaging as well as the amount of accessories provided. I should also note that updating the mixamp is very easy and is as simple as connecting the device to a computer and downloading the Astro Command Centre software from the manufacturers website. This is available for Mac and PC. Updating takes seconds and the software also allows you to create your own presets.
The device itself has four pre loaded press including astro's own mix as well as options for media etc.
Now the area where this item achieves it's 1 star rating is it's Dolby Surround Sound mode which i primarily bought the item for. Unfortunately when the setting is active all bass is removed from the sound and when explosions or wind are in the scene there is an audible tinniness or echo. Almost like watching video on a pre smartphone mobile. Turning this mode off solves the problem and a rich bass returns with no distortion. I have now tried this with 2 separate units and multiple headsets from different manufacturers and the issue persists. Further investigation online highlights this as a "known" fault that is affecting many people. Sure the mixamp works without DD but I can achieve the same thing (stereo sound) by plugging the headset into the controller of either an xbox one or ps4. Another issue being that there are two versions of this amp, one for xbox one (this one) and one for PS4 (the black one).
So unfortunately until the manufacturer delivers a fix (software or hardware) this item can't be recommended despite it's many positives because one of it's core features simply does not work.
