Rumors that Apple is getting ready to unveil iPhone 7 without a 3.5mm headphone jack are starting to gather pace, and now we have a Chinese accessory maker showcasing not one Lightning-to-3.5mm headphone adapter, but three.

We may have only had the iPhone 6s and 6s Plus for a few months, but there’s already plenty of speculation running rife about the future of Apple’s wildly popular smartphone. We have already been told time and time again that Apple is planning on shipping the iPhone 7 without the inclusion of the standard 3.5mm headphone jack. Until now that has been based purely on speculation and analysis from industry insiders, but with a discovery in iOS 9.3 beta 1.1, those speculations have been given a solid foundation. The code suggests that the removal of the 3.5mm headphone jack will in fact become a reality.
