I grabbed a pair of PI7 on amazon warehouse during the last prime days, with a good 30% discount on their used/very good price, and I guess this helps me giving a non-biased judgement.
I didn't expect such a v-shape signature and boomy sound from the most premium tws, I'm not a basshead but I like some bass hint on hearphones, sometimes. All of the reviews are misleading or ambiguous in my opinion, they are like "it's a v-shape sound but there are worst cases". No, a product at this price point should be more than "better than the worst", in every aspect.
So I started (again, as I've been doing it in the last months) looking for a PI7 frequency response, and I found a comparison made by Oluv on youtube where he shows his measurements. I used it for creating an autoeq file for wavelet that I'm posting here; the compensation has been hand made in primeeq, so it isn't perfect. I'll probably keep working on it, I don't know if it causes clipping.
I was aware of how batteries, software, volume, bt range and touch controls are also poor in PI7s, so I won't complain about it but I need to point it out one more time to people reading this post.
I am undecided whether to keep them or not, although I paid 130€ less than their price. I can barely accept hard eqing a premium product, that furthermore have other shortcomings and flaws. I am a bit "PI"$**d off
.
Copy and paste in a txt file and import it in the autoeq section of wavelet; import and search for it (type the name of the txt file) then search it again with the icon at the right of "headphone model".
