Amazon was kind enough to immediately send a replacement and the replacement started to double click after just 3 days. 5 inches long, so I know they havent grown larger)--so I ordered these in a 5, but they were just a bit too short! Im listening to these, just tripping out and amazed at the SQ. People on the other end said that it sounded very good. This device is great for finding things like lost keys etc in your house, but if you were to lose them in a city, you wouldnt know exactly where they are, however because the App and the Tile communicate regularly the App would know the rough location that you last had your keys with you, so you could head back to that location and see if you can get a connection to the Tile again. I can wear these sandals 12-15 hours a day and their comfort is so outstanding that I dont even feel them on my feet. After about two weeks of using these earbuds daily, here?s my honest review of them:Pros1. They do look quite big on your head so they will never look subtle. I can only imagine how amazing my feet will feel in the right size. A good purchase
