For a standard recable (non-removable) with the Midnight cable it's about $75 total. I went for the removable Starlight cable with Memory Wire which came out to $150 total. All I got's an iPhone as a camera at the moment, but they look real nice.
I'm assuming the next iPhone won't have a 3.5mm port so I might as well just get a phone for music only. I'm not a big fan of DAPs and theyre clunky interface.I find the amp in the iPhone 6/6S lacking. I'm almost always at 75-100%
I just sent my GR07 MK IIs to BTGAudio to be recabled with a removable cable. Mine have been broke since february. Cant wait to get them back. There's nothing quite like a good pair of portable audio gear. I could live withoutnheadphones but not without something for on the go.
