Yes, the React is a one trick pony. But its one trick is that it's great for pinpointing enemy locations...which is exactly what you said you were looking for. Hence, why I mentioned it.

The headset you've linked to looks like a classic OEM rebadge, where they've bought an off-the-shelf headphone and detachable mic and stuck their logo on them. I have a similar-looking mic in my closet that I got for free in an Amazon bundle with my X2HR. I didn't have a great time with it. Might be a different mic, but no way of knowing without buying one.

If the frequency graph they've provided is accurate, then those headphones will sound excessively v-shaped.
