I actually just turned on both earbuds and my phone automatically picked it up. Again, with my phone, the WH headphone, the app. These are a great bang for your buck! The fit for the bottom half is snug but wish the lid had a little extra grip. They are 100% authentic and are very nice. Now in case you might be thinking that it might have been "user error" I have managed to pair my phone with the Fitbit Flex and with the Bluetooth in my car, so I dont think it is me. * The clamp is pretty study and has a nice locking mechanism. Its made of cheap metal. I was watching a movie while putting it together - I took my time and was somewhat distracted, so it took me about 2. I have worn their slippers (size 10) for years but the footbed of these are narrower than others.
