I'm surprised at all the professional reviews and customer reviews for gaming headsets lacking any examination on sidetone. No one in writing or in their videos give more than an obligatory mention of the sidetone feature, and that is just to confirm that the product advertises it. If they paid any attention to the actual sidetone, they would notice quickly that certain headsets lack it so much that it's basically false advertising.I'm here to say that the sidetone on this wireless Razer gaming headset WORKS.Yes, you have to max out the volume dial on the headset itself. Yes, you have to max out the sidetone setting on Razer Synapse 3, but it works and comes through loud and clear as you talk.It is comparable in comfort to the Razer Nari, albeit with slightly smaller earcups. It's lighter than the Nari wireless (non haptic feedback) despite having the Kraken v3 pro having haptic feedback motors. It's not as comfortable or lighter than the Blackshark v2 Pro. But it is more than adequate. I had no problems wearing it for hours.By comparison, the Blackshark v2 Pro's sidetone does not work. The Razer Nari wireless sidetone is "okay" but on the quieter side. The Blackshark v2 wired model works fine, loud and clear sidetone. Razer's wireless lineup when it comes to sidetone has been poor, at best! Honestly, if the Blackshark v2 wireless pro had functioning sidetone then I would have stopped there. It is light, comfortable, fits my giant head, and has a great mic. But their advertised sidetone does not work at all in practice and it's a widely reported problem.The Kraken v3 pro has good comfort, decent earcups, great gaming/music/movie sound for my non-audiophile ears, a good detachable mic, nice rgb on its sides, and clear sidetone (finally from a Razer wireless headset) in practice. It was my primary need for getting a wireless headset. That, and being comfortable enough to fit my giant head!The Logitech Wireless Pro has great sidetone but is uncomfortable, barely fits my head.The Corsair Virtuoso XT fits very awkwardly.
