Does it have a regular headphone jack or is it a proprietary jack as well that you can only use their headphones?

It has a micro USB looking headphone jack that fits the headphones they provide. Also works with bluetooth though.

It has a regular headphone jack. Believe it or not, this cellphone watch actually functions quite well. The main problem with is (as you would expect) is battery life.

Prolly nothing. It could be just a case of advertising. I've only used it in iOS devices, but a headphone jack is pretty standard. That being said, the app one uses with this cable may be iOS only.

I see a "line-in" jack and the 2 speaker jacks but no headphone specific jack

No, unfortunately, these headphones use a proprietary abomination of USB. One end of the connector cable is regular USB to plug into your computer or charger, the other end that connects to the headphones is some sort of micro USB-ish connector... but it's not micro USB.

Yes, there is an auxiliary input that uses a standard 3.5mm headphone jack.

The headphone uses the regular small plug and it comes with attachment for larger jacks.

You can use any standard waterproof headphones with a 3.5mm jack. In fact the headphones that come with the unit are kinda cheesey and I was blaming it on the unit. Then I used a medium quality headset and the sound was dramatically better.

Yes should work with a standard headphone jack. The sound quality is awesome.

It is a standard mini-earphone jack like all portable devices. I have used these on my phone, an HTC, move to laptop and desktop, no problem.

It only has a normal headphone jack. You would need some sort of headphones that plugged into the headphone jack. A bluetooth transmitter + wireless headphones for example.

I've had mine for a couple of years so maybe they've updated the model, but no, mine doesn't have a headphone jack.

Yes it has the headphone jack. Haven't tested it though. As for the battery, it is built in, it's not accessible unless you open up the laptop. Related to that, there is an extra connection below the laptop which reviewers believe to be an additional connection for a future external battery upgrade from the existing internal one.

It has an auxilliary input jack to allow input from other sources, but no headphone jack or audio out jack of any kind. You can view the owner's manual at this link:http://www.devicemanuals.com/pdfviewer/pdf-manual-389820.html

Yes, standard headphone jack does work. It is a flip open silicone rubber cover, not a screw.

Yes it has just a normal headphone plug in ... If anyone has a lifeproof case it works fine with the adapter also.

It's a Bluetooth thing, Bluetooth requires it if you use their proprietary technology

I have one myself and I like very much but as far as I know there is no headphone jack.
