Two qualifications on the recommendations:
On the Q30, they actually can be wired, but I would only recommend them for good wireless sound, with the attraction that they are sold with an audio cable and can be wired should your battery run down. I haven't tested whether they can be charged while you're listening wired, though there are probably many reviews that cover that.
On the 7506, they are mostly "bullet proof". Most experienced owners can tell you that the original ear pads will have to be replaced, relatively frequently, depending on usage habits. Fortunately, they are replaceable -for a few to several dollars, though you'll want to factor that into your cost assessment. You'll also want to learn to shop for good replacements, and be patient because they do not just snap in, and Sony do not to sell replacements. Fortunately again, because of the popularity/sales of the 7506, there have always been many replacement-pad options. I usually keep a spare pair because I'm confident that I'll continue to depend on the 7506.
