Agreed, but I would also argue that they do have benefit because a lot of people are very prone to Placebo effects. It think it was ADTG who cited that people (some anyway) would hear better, even night and day better sound if the device is more expensive. The same would go for better specs, measurements, or even the look. All else being equal, the better looking (to the individual) one will always sound better. Like, all else being equal (thankfully all else are not usually equal), the taller (man anyway) one will get the job.
Food, same thing, the better looking dish always taste better, again, all else being equal.
