JBL Boombox 4 (PL Version) Battery life
just if anyone else was curious about battery life, i’ve tested Boombox 4 “PL” (with old “sub-bass” firmware) at exactly 50% of volume with various genres of music, and this is what i get.
- at first (1 & 2 ss) i tested 1 hour of playtime WITH bass boost deep, and custom eq. battery went from 82% to 63%, which gives us -19% of loss
- at the second time however (3 & 4 ss) i tested 1 hour of playtime WITHOUT any bass boost, and custom eq. battery went down from 62% to 49%, which gives us -13% of loss
(⚠️<125hz slider was on -0.75 on the first test, however on the second test it was on 0. not big of a difference, but i think it’s worth to mention)
my custom eq that i used for this test is shown on the last screenshot
