So, the last 2,5 days I'm comparing the px8 and my AirPods Pro 2 (APP 2). Maybe the people here remember that in the Bathys thread and in this thread, in the photos I posting, I always including the APP 2 because I think is really a excellent earphone in many ways, including very much the sound. Because all this weeks I'm comparing only the Bathys, 5909, px8 and p7w, I never in fact comparing the sound quality of APP 2 and px8 directly at the same time.
My conclusion last night is that I prefer the sound of the APP 2 than the px8, the APP 2 is having a more correct (FR) sound that is great for me, and this is even with my EQ settings in the px8. Without EQ, the difference is even more evident in favour of APP 2.
Today, I'm using the 5909 again that I putting for sale here in Head-fi some weeks ago and I deciding comparing again the 5909 with the px8. Wow, I have a surprise seeing how much I preferring the 5909 even when using EQ in my px8. Before I already know I preferring the 5909 sound (and the Bathys too), but I forgetting that the difference with the 5909 is more big than I'm thinking before.
So, even after having really great 30-32 volume steps (so important for me) in px8 and a better carry case and maybe even little better ANC, the 5909 is still sufficiently good in the volume area (never so terrible like the Bathys in this aspect) and I have the excellent APP 2 for top level ANC and great sound too for travelling.
So, I will returning my px8.
