Oh that’s true, my headphones with noise canceling were also over-the-ear. I found that turning on the noise canceling worked great and brought down the sound of a lawnmower really well by playing sound waves opposite the waves of the motor to cancel each other out. I wasn’t thinking about another pair of ear buds.
The wireless headphones that I was using went around your head and didn’t pump the sound directly into your ear, but were supposed to use some bone conduction. I’m not sure if that’s part of the battery issue that I saw. I just know that my phone itself would die before the end of my shift if I was using Bluetooth headphones (provided the headphones didn’t die first) and I would still have battery left after using wired earbuds.
I can remember a time that after a search, you’d just have a list of links. No extra boxes on the side or even an images tab, just the list of links. At the bottom of the page was the word “Google” and there would be more O’s, as they were links to other pages of results.
If there were sponsored links, it didn’t say so and you’d end up with different sites at the top of the list. So I don’t think way back there were.
