Straight to da point: 1. Start up Razer Synapse auto select previous selected audio interface in Razer Surround. This is annoying. It always default my selcetion to my build in low quality speakers but not my Razer Banshee. The reason of auto start up Razer Synapse is to increase accessibility, but why not Razer Surround? 2. Equalizer Presets for Razer Hammerhead V2 rearrange The sensitivity of Razer Hammerhead V2 is 102+-3 db. And Equalizer Presets had way more than that. Thus I heard some noise and discomfort sound... But after I manual adjust the equalizer everything is fine 3. Bass Improvement This one is serious case (IDK, maybe). I have Razer Banshee and I installed Razer Banshee Configurator. Now, coming to bass. When I use Razer Banshee Configurator with Razer Banshee, I set Equalizer to Techno (Yup, I like Techno) Da bass is amazing! No need adjustment. However, when I change the configurator to Razer Surround(Turn off the Razer Banshee Configurator totally), and set the equalizer to Techno too. The result of bass is very low. (Please note that I turn off all the enhancement section.) After I adjust the enhancement section to optimum, I got the same hearing experience like Razer Banshee Configurator. However, if I mix Razer Banshee Configurator Equalizer with Techno while using Razer Surround Enhancement the bass is PUSHED TO MAX without reduce any of the hearing experience. IS JUST SO GOOD! Thus I believe there must be something can be done to improve the bass. What I hope is Razer could mix these 2 configurator to maximize the bass.
