In what way? I use them and it works just fine. Plus, I already had one so it cost me nothing to use it with my phone.
those clip-on ones are always awful.
Again, how? The ones I have seen used work perfectly fine, plus there is a large number of devices to choose from; I am sure they aren’t all awful.
Plus it’s splitting the battery life between two devices, nothing bugs me more than using my phone for everything only to be shocked that the battery dies twice a day.
Most people carry a charger or battery pack with them anyways so that is not a problem. Besides aren’t you already powering two devices when you carry this thing around with you… I’m gonna guess you have Bluetooth headphones too, so that’s 3 devices now.
