How to measure frequency response of a speaker at home

Does Soundcore Motion+ Sound Different via Aux-in and Bluetooth, and How to Measure Frequency Response at Home Short answer: no, Soundcore Motion+ sounds the same via bluetooth and aux-in. Today I noticed that my awesome bluetooth speaker Anker Soundcore Motion+ sounds kind of shitty.

I would have ended the investigation at that, but I usually listen to music on Motion+ from my laptop, connecting Motion+ through its aux-in port and using an external audio interface iRig HD X because I also use my Motion+ to play on Linnstrument. I reverted the EQ settings to the custom setup shown in the screenshot above and decided to compare the sound via bluetooth from my phone and via aux-in from my laptop. I felt like it sounded a little better when played from my phone, but I wasn't sure and suspected that it might be a placebo-like effect - finding signal when in fact there is none.
