[M] SteelSeries Arctis Nova 7P Wireless Gaming Headset Review
 

When compared to the Arctis Nova 3, the Nova 7P sports a very similar sound signature, since it is using the same set of custom speaker drivers, 40mm with a frequency response between 20 and 22kHz. We tested the headset in both multimedia content and games, and we really enjoyed the combination of crisp highs and great sounding lows, even when using the default EQ. The price difference exists because of the WiFi/BT convenience, which does even allow listening to two sound sources at the same time, the great battery life during a single charge (38 hours) with fast charge support and overall, we are getting increased liberty of movement given the operating range.
