My approach to solving that problem in software was to play music through an app with an equalizer where I could cut several dB across all frequencies (see my other post above). Now I can use much more of the system volume range with the rocker buttons before I reach a painful volume. If you're listening to something like YouTube, or streaming audio through a web browser, then a music player app isn't going to cut it for you. There are some systemwide EQ apps, but I think they didn't work well (or maybe at all) on my 2014 Moto X, so I can't recommend any specific one.
