I don't hear any huge differences from burn-in myself anyway, I've slowly increased the volume on my Vsonic GR07 MK2, with very very harsh music, like extremely loud static, it's probably over 125dB now, if I have the Vsonic 2 metres away from me, it sounds like a laptop speaker on low volume, I have to put pillows all over it, and even then I can still hear it quite well.
I don't know if it was a break-in experiement or a "can I break it" experiment, lol.
Sure, I think it sounds different now, yeah I really do, but not more than 10% different. The only way I'll truly convince myself, is by taking it to a local store here, and comparing it to their Vsonic GR07 Mk2, I think there are two stores close to me with them, so then I'll see. From one IEM to the next is more like 200% different, then using a nice DAC or amp is only 5 or 10% different, however those slight differences can be quite surreal.
When you're fresher in audio (not saying you, just in general), you're more susceptible to expectation bias and short term memory. These days, the entire character of the sound just gets uploaded into my head so I remember store auditions well.
