I demoed the Px7 S2 home for one day, here are my impressions in relation to my PX7:
- Worse ergonomics for me - the placement of the joint between the headband and cup in a higher position (vs. PX7 - middle) combined with narrower headband arc is unfortunate because this generates more pressure above the ear than below the ear - feels unbalanced / not secure especially when walking. I think I saw someone else mentioning this aspect.
- Smaller pads, my ear touches the upper inner wall, the return to a more rectangular shape is a mistake, oval/larger PX7 pads/cups = much better.
So, for me all the comfort benefits of softer pads/headband/less clamping are denied by the two points above.
- The rounded/bulged play/pause button on the PX7 is easier to find by touch than the new ridged button on the S2.
- Laggy / buggy wear sensor on the S2, it takes 2-3 seconds to pause when headphones taken off. PX7 - much more responsive.
- Fewer ANC presets - low/high settings are gone, only "auto" now, which is supposed to be better at determining the amount of ANC needed, but I still liked the manual settings better because I only used "low" for my needs.
- Long press on function button for "Ambient Pass-through" is gone
. On the PX7 you could set a lower customizable volume level and engage external mics in one step - long press. On the S2 you need to pause the playback with one button and cycle through ANC/OFF/Passthrough with the other button. Really stupid to have this "quick attention" function as is in PX7 removed from the S2...
- Vocal prompts are gone / only beep prompts.
- Much narrower sound stage, sounds more closed-in, less sparkle, less dynamics, less articulation, woolly slow bass although is less in quantity. Here I might be biased / my ear tuned to original PX7, but still the narrower sound stage is very obvious.
All in all a step down for me, the only single point that S2 might win is that they could be regarded as more visually pleasing, although I still like the sturdier more industrial look of the original PX7, with the carbon fibre composite arms. So I'll keep my space gray PX7 for now, the PX8 also makes no sense for me because the same physical form as S2 / same ergonomics problems.
