Creative needs to stop using digital volume control tied to the operating system and I'll explain why.
With high sensitivity headphones you end up with an extremely narrow range of volume to work with. For example, 0/100 is mute and 5/100 may be loud. That means you have 5 different levels of loudness which is far too little. I had this exact problem with the E3 and you just can't live with such coarse adjustment. It's also dangerous because if something does reset the volume to 100/100 then it will destroy your IEMs and your hearing. This is why volume control on the E5 should never be tied to the operating system.
I'm sure they've made the same mistake with the G5.
Digital volume control tied to the OS is fine. Plenty other companies do it without any problem. The issue is gain. Even if you have analog volume pot, you will still face the same loudness issue (and probably additional imbalance issue on lower volume range) if the gain is too high. So instead of taking away digital volume control, they should refine it and make better gain range selection that are suitable for both low, mid and high sensitivity headphone.
