Hello! Your English is great!
Sadly, due to the failing of Gibson (the owners of the Phillips Headphone brand) the SHP9500 was recently discontinued. So they’re getting harder and harder to find. So it’s much easier to recommend the Pro 82 as it’s the one you can still buy.
Having said that if you forced me to pick….I’d still go for the Pro 82. Its adjustable bass feature is fun, and as to your detail question, it brings out those ranges more aggressively than the 9500, which has more of a laid back sound.
The Pro 82 ear pads are slightly more comfy than the scratchy cloth of the 9500 in spite of how warm they can get.
I hope that helps you out. Thanks for writing!
