Funny story. I bought a 64GB OnePlus when I switched to Android. I assumed I'd sync up with iTunes and shit. Except T-Mobile offers free streaming from Google Music, and Google Music syncs with my iTunes, so my phone has literally no music on it, and I listen to literally my entire music collection. For free.
Google Music is life. Same price as most streaming services, includes streaming and 55k songs worth of cloud storage, plus it comes with YouTube Red, ie no ads, background/offline play on mobile, and the one decent YouTube original they've produced. Plus they pay artists better than almost anyone.
I never really understood the 1/4" jack until I realized that I have owned my headphones with the 1/4" jack for longer than I know my wife, I bought them used, and I've run over the chord with my chair a couple hundred times and still I've never had any issues with the cable. Compared to the 3.5MM cable for the JH4 IEMs that I had to replace 1 year and 6 months after use because the LH earpiece stopped working ($35+$15 shipping, what a ripoff).
