Because they’re effecfively measuring the change in the students’ performance in the STROOP and ADD tests before and after a heat wave, baseline factors such as wealth and income should be controlled for.
They note in the results that in the initial tests there was no significant difference between both groups’ results.
Honestly the average user should probably go wireless. The convenience factor is huge, and most of these new headphones come with active noise cancelling.
The average pair of wireless headphones is also good enough for casual listening (depending on codec) and can come pretty close to wired solutions.
That said, I would never go for wireless on ear/over ear headphones again. The more features something has, the harder it is to fix when something breaks.
My wireless solution is a set of mmcx in ear monitors connected via Bluetooth adapter. Even without active noise cancellation, they block out sound well. For desktop my job requires critical listening, and I like neutral signatures, so I’d rather stick to desktop monitors and wired solutions.
I was visiting there in 2019. Of the hundreds of thousands of balconies there, I saw less than a hundred with lights on ~10pm.
It’s far away too. ~18km to get there from Iskandar Puteri (not intensely dense, but sees some traffic due to legoland), and ~35km from Johor Bahru (the main city area of Johor).
They must have done the whole build it and they will come thing before realising no one wants to live in a ghost town.
At least it looked kinda impressive???
