Hmm, the 3.5 jack fits in tight into the adapter (at least with the iPhone supplied one) so it would be pretty hard to lose on the move in my opinion, it's literally like a small extension of the existing lead, it's not going to come loose unless it's tugged with force. The only way you're going to lose it is when you misplace it after using the headphones as normal. Again, depending on how much of an audiophile you actually are, and I'm wondering if anyone in this thread that uses wired headphones actually has a pair that are so expensive you use religiously on your commutes, just have an extra pair that's used with the phone. I have wired headphones at work, and wireless ones at work, I have loads of wired headphones at home, and 2 wireless pairs at home. None of these headphones cost me anymore than £20. No one really goes out knowing they are going to be using their phone loads with less than 50% charge, and if you do, you probably already carry a powerbank, so it's horses for courses. Also the Pixel 2, didn't have a headphone jack did it? Amazing that 12 months on, next model of phone on, and this is still more of a sour point than that fucking ugly notch!
