I took a stab at the personalization. Now… given that this is a personalized hearing test that requires an individual and not a test fixture, it may be a different result for each person.
For the sound personalization, you can choose the intensity of the DSP, which is really useful, however for this test I wanted to show the maximum effect to get a sense of what the difference is.
In general it reduces the lower mids by a noticeably amount, by upshelving the upper mids and treble (ear gain) with what seems to be a comb-like effect.
Here it is at 50% relative to a 10dB slope.
Here it is on GRAS relative to Harman:
Note the positional variation around 1.5khz!
Here it is smoothed to the same degree as Harman:
I probably wouldn’t go more than this as it does tend to get quite bright when turned on maximum.
I’m going to keep doing some testing but overall I quite like the implementation here for when you’re using the Bathys on the go and don’t have access to EQ software. For those who found the Bathys too warm, this makes it far more suitable.
I still want parametric EQ or the ability to input specific values in the app-based EQ options, but this is a very nice alternative. More importantly, it shows Focal welcomes personalization with this platform and that’s great to see!
