Update: I added a new version, which in my opinion is much better than the first one I shared on this post. I'm keeping the first one for historical purposes, but I don't use it anymore.

Got a new PC at work some time ago. That means I lost all the EQ settings that I used with the Creative SoundBlaster E1 external amp/sound card. Thankfully I still have the EQ settings for my Audio Technica ATH-M50 headphones here. But I lost the ones for my Bose Soundsport Wired earphones. Just another reminder to save your stuff to devices/locations that you control.

Anyway, I had to start from scratch with my Bose Soundsport Wired earphones. These earphones are bright sounding earphones. They don't have that much bass to begin with. This is where an external amp/sound card with EQ settings can come in handy. Using the built-in “Rock” preset from Creative, I modified it to add more bass. The result was surprisingly good. This setting sounds even better than any of the previous EQ settings that I've made for my Bose Soundsport Wired earphones. There is now enough bass — more than enough for these earphones — but with minimal degradation to the mids and highs.

These are the EQ settings that I use most often when I'm listening to music at work. I have an Audio Technica ATH-M50 headphone connected to a Creative SoundBlaster E1 external amp/sound card, which is then connected to my work PC via USB port. With these settings the ATH-M50 comes alive! There is ample strong clean bass, while the clarity of the mids and highs are still maintained.
