These headphones are excellent! I wasn't sure about this necklace style that I keep seeing, but I wanted to try it. I was surprised at the flexibility of the neck piece and the comfort of it. It's so light I barely noticed it. The Bluetooth connection seems to stretch about 20 feet before it begins to crackle. The sound has good clarity. My biggest concern would be the size of the bud that fits in the concha - it feels smaller than Apple's, but still larger than I prefer. All in all, an excellent pair of wireless headphones.
