I ordered a 9, as suggested. I even tried going all the way down to easy so I could at least get through the story, but it barely helped. They look nice and are easily adjustable if necessary. The built quality is sincerely 4/5. The texture of the ear pieces just does not stick to your ears. Ich bin sehr zufrieden mit diesem Kauf :-) Zudem rauscht der PX7 etwas stärker (stört aber nicht wirklich). This is a great little casual dress! Overall this is one solid and powerful light for handgun or long guns. I have 3-stars for now.
