Finicky to put together, and the connector pieces are fragile. I measured mine and they are 5. Very pretty but the run small Not soft enough and changes the sound signature- increased bass less sound-stage and less mids/highs. Good for walking. They are precious earrings. These were super easy to install. Dann lässt man die andere Hand wieder los und muss ggf. Ive started taking it with me on hikes with a hiking friend. I like the pink color but thats about all this slipper has going for it.
