Recently a company that deals with mobile accessory had posted a video recently which showed what could be the official lightening ear pods of Apple. In the video it could see how it worked. In between, there was a lot of news pertaining to the incident that Apple had made an official announcement of the removal of the 3.5mm headphone jack while releasing the iPhone7. This is why; it could be safe to assume that the company has plans to release these ear pods along with the iPhone7.
It was claimed by many videos and photos of the iPhone7 that what is being seen is something that cannot be said if it is a mockup or the real thing. However, there seems to be a lot of motivation for the mockup phones creation which will allow various accessories and cases, with this the possibility for creating fake earphones is said to be less incentive.
In the video we can see the demonstration of the 3.5 ear pods work. We can also get to see a consistency in the design which is said to be high quality. There have been photos of the same which had appeared sometime back.
We are yet to know 100% if the Lightning Earpods will be supplied by Apple along with the iPhone7, however it does not seem to be something that can be confirmed. If you talk about the ground of the cost, the supply of the wireless earphones is something that could be ruled out. There is also word about the fact that there are plans that the 3.5mm lightning adaptor would be supplied. In order for the promotion of a new standard, this method could be a really odd manner.
There are a lot of options that would be available for you if you have any plans to opt for the route which wireless. Then you can choose from the basic and cheapest to the top end one.
