While it might not have any RGB lighting, the BlackShark V2 has plenty of other, more practical features to bolster its versatility.
My favourite of these would have to be the volume control. Rather than the typical scrolling wheel found on many headsets, the BlackShark V2 includes a full-blown dial on the surface of its left ear cup. The dial's larger size makes it easier to adjust on the fly, plus there's a handy notch at the half-way point letting you know when you're back at 50% volume.
The one downside here is that headset volume is distinct from system volume. That means you don't get the on-screen slider showing your current volume level as you turn the dial. It also means that other volume controls such as a volume wheel on a keyboard don't adjust the headset volume, just the system volume. It's not a big issue, but it is a trade-off you'll have to make.

Rounding out the headset controls, you'll find a mic mute button situated on the underside of the left ear cup. It's an asymmetrical toggle, popping out further when the mic is active so that you can check whether you're muted or not with a quick brush of a finger.
The BlackShark V2 supports two methods of connectivity: via the included USB sound card or through a standard 3.5mm headphone jack. The USB connection is compatible with PC, Mac, PS4 and Switch, with the 3.5mm connection necessary for other devices.
If you want access to all the BlackShark V2's features, you'll need to connect through the USB sound card and boot up the Razer Synapse app. You'll want to, as well, since the app is the only way to activate and customise THX Spatial Audio.
By default, THX Spatial Audio calibrates itself according to the app currently running. It switches between three core profiles, each tuned to their respective media: Game mode, Music mode and Movie mode. If you'd prefer a little more control over the calibration, you can set modes on a per-application basis or you can create custom modes based on your spatial preferences.
Synapse lets you tweak plenty of non-spatial audio settings, too. There are sliders for bass boost, sound normalisation and enhanced vocal clarity, along with a full audio equaliser for adjusting the volume of different frequency bands.
Mic audio is just as flexible. You've got toggles for mic boost, volume normalisation, vocal clarity and ambient noise reduction as well as sliders for mic sensitivity and mic monitoring. The latter option controls how much of your own voice is piped back through the headset to your ears. There's also a full equaliser for the mic audio, too, should you want to tweak frequency volume levels to better suit your own voice.
For folks who want optimised audio without having to adjust toggles and sliders, the BlackShark V2 supports THX Game Profiles. These are pre-configured profiles based on individual games, either created or endorsed by the developers of those games. Each profile offers two modes: Environmental mode and Competitive mode. The former emphasises immersion, aiming for a more realistic representation of sound cues in the game's environment. Competitive mode, meanwhile, amplifies the most-critical sounds like enemy footsteps for higher situational awareness.
Currently, only a handful of games support THX Game Profiles, including titles like Apex Legends, Destiny 2, Call of Duty: Modern Warfare and Red Dead Redemption 2. More games will presumably join that list in the future, though that will likely depend on how popular the feature ends up being among competitive players.
