Unrelated to anything recently posted, I finally got replacement cables for my Massdrop Sennheiser 6XX headphones that have in-line iPhone controls so I can wear them while walking the dog and control my music / talk on the phone. My iPhone SE drives them to loud enough levels that I don't feel I absolutely need a portable amp. That was a worry for me, because as far as I know there are no portable headphone amps that allow passthrough of music control or vox, and I didn't know if the phone would drive the 'phones with enough volume.
No worries. They are stunning.
I live in Calgary, where the weather hit -30°C last week, and I've walked the dog in -25°C weather a couple of times recently. I wore my AKG 551's for that, because they're closed and keep my ears warm in cold weather, and came phone-ready with inline controls. They're 32 ohm, so the phone had no problem driving them, and with a toque and hooded puffy jacket, they keep things bearable. But it's gotten warmer, only -10°'s and -teens for the last few days, so I broke out the Sennies. Wow. I'm walking the same route, at the same time of day, and listening to the same music, and I cannot believe how natural the open-back headphones make music sound. I'm in awe. It's no wonder the 650s were Sennheiser's top of the line for so long, they are truly impressive and worthy of being reference headphones.
Pretty much every review of mini-monitor speakers compare them to Rogers LS3/5As, and pretty much every review of circumaural headphones reference the Sennheiser 650s. I'm glad and proud to now own both of those products. Each, in their own way, defines how reproduced music is heard, and I'm glad to have each of them for a baseline.
To bring this back to this thread, if Schiit could figure out how to make Fulla 3 pass-through the mic and music controls in TRRS cables, I would be a happy camper. To get better amplification but still be able to answer calls would make me one happy dog walker...
