A headphone jack is a headphone jack. There are many variations, lengths, etc., but usually a GOOD manufacturer will include ADAPTERS, such as the mini jack pass-through adapter to a 1/4" jack for receivers, recorders, etc. (i.e., the professional standard).
Lightning jacks will go the way of Thunderbolt..... only Apple will insist their users upgrade to them, while waiting for 3 years for the adapters and the actual headphones to appear. FAIL.
I just may stick with my iPhone 4S for a bit longer. After all, my $300 Bose Comfort 15 over-the-ear headphones are a $100 more expensive than Beat-Me-Silly, and they are made of better quality and have a fantastic trade-in policy (if your Bose headphones fail outside of the warranty period, they will sell you a new pair for $99, instead of having to buy a new pair at $299. Top that, Apple!).
Not only that, but the Bose headset adapters for Apple iPhone include a variety of adapters to fit other smartphones, dumb phones, etc. Apple doesn't do that, either.
Bose: 1. Apple: 0. Beats: -1.
