I also use them as my primary ear buds. And no, no news on a Lightning version that I've heard of. I'd speculate that it may happen, eventually, but, I'm not really sure of the future of this product since Apple bought Beats. Only time will tell.
I love my Bluetooth Jaybirds, so the in-ear headphones are my rarely-used backups, but I too enjoy them, and would be happy to pay for a Lightning version.
