Hello Heedong, we really apologize for missing your, question. Bass and treble amount calculations are straight forward. For Bass it’s the arithmetic mean deviation between 20 Hz and 250 Hz to our target. For Treble we chose to do the calculation between 2kHz and 10 kHz, The results are more reliable and more audible on that range so it is giving an amount more representative of what people experience to not include the highest octave (10 kHz-20 kHz) in the calculation.

Hey there! Is it possible for you to tell me what measurment rig used in v1.5 (that you used when testing JBL Tune Flex) and which microphone was used in that measurment rig?
Thanks, Best regards!

Hi there,
We measured the “JBL Tune Flex” on the Head Acoustics HMS II.3. which has an acoustic coupler that complies with the IEC 60318-4 standard.
Cheers, Dagobiet

I’m not seeing you mention which volume you’re testing this on? I see abysmal result on Bose Ultra Open Earbuds that looks like you measured it on maximum volume, which effectively makes the test invalid since that’s not how open earbuds work from my experience. They are meant to be listened to and accurate at around half the volume, anything above that can be considered a sort of a “boost mode” for listening to overly silent podcasts in a loud environment for example, you’d never actually listen to music like that, it’s painfully too loud and obviously super distorted.
As you change volume, you can literally hear the sound profile (some internal EQ) changing. You can’t measure on loudest volume, conclude they are inaccurate, and give them a bad rating on neutral sound. In my experience when testing against my studio monitor speakers in an acoustically treated room, they are amazingly accurate. It appears like your testing methodology here is completely invalid for this use case.
