UPDATE: These are good earbuds for the price. The replacement devices worked better with our phones. We've found that the earbuds don't work vice versa with the Fitbit, they're not compatible so they don't have a good Bluetooth connection. Other than that, they're great to use with my phone and tablet. I really wish they liked the earplugs. They fit well and the sound is pretty good. The problem is that we bought two pairs and they both have the same problem; they cut a lot. Mine works fine holding my phone or laying it on my desk. But when you put the phone in your pocket, they cut it out and more. My wife bred here with her smart watch and she also got many carvings even with her watch right next to her. I checked the MPOW website and it just says the signal strength is boosted. These return.
