Great price on the whole 'SteelSeries Arctis Nova 7' range it seems all at Amazon DE via AU. Not bad pricing considering an RRP of $399, however ~$275 seems like "Reasonable" Retail Price.
SteelSeries Arctis Nova 7P $241.03
SteelSeries Arctis Nova 7X $251.63
SteelSeries Arctis Nova 7 $263.09
The Nova 7Ps were $268.83 at Amazon UK via AU late last year.
Price of the 7P is showing $306 for me
