The problem is that they are so expensive for what they are, considering they sound is no better than the free ones they 'give away' with the phone. If they were up to the sound quality of their premium apple earbuds which they normally sell for over $100, then they maybe worth it. But I guess they would be good for using with an apple watch, so you don't need your iphone with you. But if you have your iphone with you, you may as well just plugin headphones. I never have a problem with wires, and infact the wires stop them falling o the ground when they fall out of my ear. I would be scared of these ones falling out and hitting the ground, as the shape of the current wired ones fall out all the time.
I think the iphone 7 is a great device, and the big plus is that it is water resistant, and probably the most powerful phone on the market, as it is tuned for the OS. I have also found apple devices very reliable compared to other brands. The lack of a headphone jack is annoying, especially if you listen to music while charging. But most of apples new devices now seem to need multiple dongles for some things.
Saw an article the other day that the Samsung S8 will be without the 3.5mm port as well.
