Where I live, they don't do trade ins. We just keep using them. When I got the 6, I gave my wife the 5. Since she got her Globe Cloudphone, she will give the 5 to her brother. Here, the IPhones, as well as Samsung, are too expensive. Of course, it's not worth flying 8,000 miles just to save a hundred bucks, but when I go back to California, I might get one, or I might not. It's possible I may wait for the 8. Who knows, but I buy it outright, and obviously, do not do a plan. Then, I just put a Globe SIM in it, and it works fine here.
I don’t use mine for music - often.
But, when it’s yardwork time, I picked up a pair of RBH earpods on Amazon, which fit into my ears very tightly, and are like wearing earplugs. I then either throw on Pandora, TuneIn Radio (world-wide radio), Apple Radio or just a mix of my songs - and use that to keep my mind off the dull roar of the lawnmower or trimmer.
At my job, I can listen to music - but I find myself not being able to concentrate; or turning the music down so I can focus on my job. I’m an engineering supervisor; so it’s conference calls, mentoring, training junior engineers, reviews etc etc.
But the techno-geek in me is liking the technical direction they are going. Just do with the quality of the components in their headsets kept up with the chip and ergonomic design.
