What a shame. I almost bought them because of the Sean Olive Amazon review and how close they were to the Harman target.

Could unit variation be that big? or are Sean Olive measurements not that reliable? As I saw Sharur's review of the TUNE230NC that had a 78% predicted preference in Sean Olive's graph but measured very differently in Sharur's rig, more bloated bass and peaky in the treble.

I'm not sure. There doesn't seem to be many measurments of it.

Here is HobbyTalk's measurment of it, unfortunately he doesn't have the same Harman target to compare, so this is comparing with the Truthear Zero https://hobbytalk.squig.link/?share=Hobby_Talk_IEM_Preference_2022_Target,JBL_Endurance_Run,Truthear_Zero
