The QC20i's aren't wireless, but at this point I was willing to try anything, especially for a free set of headphones. I found that out of the whole bunch, the Bose earbuds were defintely the most comfortable. No over-the-earpiece and the inner silicone piece was much more comfortable than that of the Jaybirds Bluebuds X.
The best part about the Bose earbuds was the noise cancelling. Although the tiny little block that's attached to the base of the connecting jack is a bit cumbersome, it allows you to switch on the powered headphones and then go to another level with noise cancelling, which is superb. Can't wait to use this on a plane when I head to Texas in August and mowing my yard with it.
The sound quality, as stated before is pretty great. Podcast voices sound full and rich and music is full with just enough treble to make other sounds pop. I'll be keeping these for two reasons: 1) Because they're good for certain purposes, but not all, and 2) they were a gift from a friend.
So what's my conclusion? What headphones do I reccommend?
I'll stick with my Apple Earpods. Here's why.
I don't know if my ears are just used to the sound or what, but they are really the best headphones out there, not just for the iPhone, but for any listening on any device. They are comfortable (sometimes I forget they're in my ears), light, and most importantly, they produce great sound. I'm still perplexed that Apple ships these standard headphones and they are the best out of all the headphones I've tried. They're wired, which makes me want to try these out just for kicks, but they really are, in my opinion, the best earbuds you can buy right now. And they're only $30 - if you didn't already have a set lying around that came with your iDevice.
So like it or not, sometimes the cheapest is the best. After all the reading and researching and trying out, I found that the best headphones were the ones I already had.
