I'm somewhat surprised that people still care this much about the 3.5mm headphone jack. Apple includes EarPods with a Lightning connector and the 3.5mm dongle in the iPhone box. Even my wife who is a naysayer when it comes to technological change (if she had her way, we'd still be using Windows XP at home) has gotten along just fine with the iPhone 7.
There are only two use cases I've come across where the 3.5mm jack came to mind. First, since you need to set your device to airplane mode on flights, you can't use Bluetooth. If you're fine with EarPods, this is a non-issue, but if you use noise cancelling headphones (e.g., Bose QC35s) you'll need the dongle to connect them to the device. Is this a marginal inconvenience? Sure, but I'm only forced to wire in when on a flight and the dongle fits easily inside the QC35 case.
The second instance is that I have legacy technology, in particularly a PayPal card reader, that connects via the 3.5mm headphone jack. The newer readers for chip cards and NFC all connect via Bluetooth, so this really won't be an issue once I upgrade to a newer (and more secure) credit card processing unit.
I am one of those people who feel strongly about Apple keeping at least one phone with a headphone jack.
The low cost model is fine with me. Because it is the lowest cost model why take out the jack?
If Apple is trying to make it more affordable to more people why increase the cost by getting rid of the jack? Having to buy more expensive headphones like Apple's wireless ones. Other wireless headphones from what I read don't sound as good as wired.
Apple's headphones don't stay in my ears and they hurt my ears.
The dongle is an unnecessary inconvenience. They get lost and I would need multiples and having to carry it all the time is just dumb. My 15 year old truck uses the headphone jack to play my music off my phone to its cassette deck. I work in a school and connect my phone to multiple speaker systems throughout the school for various reasons. In the library, in the cafeteria, in the meeting rooms, etc. are a few places audio is played. The jack is a must to have when working in such environments. Old equipment has the 3.5mm jack. Too many people are too narrowly focused to see the big picture when it comes to use cases and convenience when it comes to keeping the ubiquitous little jack.
Are Apple's engineers less capable then Samsungs? That must be the case for the excuse of waterproofing to be used. Samsung didn't need to get rid of the jack to waterproof.
Looks like Apple needs to find some better engineers or stop using that lame excuse.
Apple thinking… how can we increase our profits?
Let's get rid of the headphone jack and sell some awesome $150 wireless headphones.
Sure we could sell the headphones without getting rid of the jack but it provides a good reason for people to buy our new headphones.
I know, we'll call it courageous of us to reduce convenience for many so we can increase our profits.
The Apple defenders will say it is old tech and it's time for a change.
There are lots of things that stand the test of time for good reason.
The headphone jack is one of those things.
