Blue and Silver Wireless Earbuds with Case

On our product pages a case display can mean a case-only level, case plus buds, separate left and right readings, or a percentage — and 162 of 235 pages describe no readout at all. Here is how to tell which one you are looking at.

Four of our product pages say "spatial audio". One defines it, one says how much it varies, one prints "Yes" in a spec table, and one only mentions it in a comparison. None mentions head tracking or a named format. Here is how to read the four.

A hundred and two of our product pages print a Bluetooth version, and not one of them prints it by itself. Here is what rides along with the number, which of those claims you can check, and what the 133 pages with no version at all are telling you.

Seventeen of our product pages make a skin or allergy claim, four give a condition instead, and one gives a stop rule. Sixty-four only name a material. This is how to tell which kind of sentence your pair's page is giving you — and what none of them can tell you.
