These are all wireless earbuds that have been best tested by external parties. When a product is best tested, they receive an award. These awards are distributed by parties such as the Consumentenbond and What Hi-Fi. These parties are independent, so you can be sure that these wireless earbuds have been tested objectively. With wireless earbuds, you can listen to music without a cable hanging from your body. This is on your neck, which gives you complete freedom of movement. Choose fully wireless earbuds if you don't want a cable at all.
