According to the Twitter user CoinCoin, the upcoming iPad Pro will measure at only 5.9 mm, and due to its thinness, there will be nothing for Apple to include a headset connector.
Of course no headphone jack on the upcoming new iPad. 5.9 mm thickness is quite good though.

5.9mm estimate complies with alleged iPad Pro dimensions shared yesterday at Slashleaks, which suggested the new iPad Pro would measure 5.86mm thick.
It is also in line with today's iPad Pro measurements. The existing 10.5-inch iPad Pro is 6.1 mm thick, so it would be sensible for a new model to be a bit thinner.
It is likely that the estimate of 5.9 mm applies to the smaller of the two 2018 iPad Pro models that Apple is expected to introduce, which may be somewhere around 10.5 to 11 inches in size. Apple's current 12.9-inch iPad Pro is thicker than 10.5-inch version, measuring at 6.9mm thick.
iPad Pro Dimensions Split on Slashleaks yesterday suggests that the smaller iPad Pro will be 7 inches wide (178.52mm) and 9.7 inches high (247.64mm) while the larger model will be 8.5 inches wide (215mm) and 11 inches high (280.66mm).
We have seen similar dimension estimates in Japanese rumors earlier Mac Otakara suggesting that the small iPad Pro will measure at 247.5 mm high, 178.7 mm wide and 6 mm thick, while the larger model measures 280 mm high, 215 mm wide and 6.4 mm thick.
Similarly, the current 10.5-inch iPad Pro measures 6.8 inches wide (174.1 mm) with 9.8 inches high (250.6 mm) while 12.9 inches inch model measures 8.68 inches wide 220.6 mm) with 12 inches high (305.7 mm).
Bezels on the new tablets can measure around 6 mm at the top, bottom and sides, with 7.2 mm measurement on the Slashleaks document, perhaps with reference to the thickness of the side button included.
Several earlier rumors have actually suggested that next generation iPad Pro models will have slimmer fittings all the way around, with the top bezel house a TrueDepth camera system for Face ID. The lower part is slimmer than in existing models because Apple plans to remove the Home button.
Coming back to the prediction of no headphone jack, this is not the first time we have heard that reputation. Back in July, Mac Otakara also said that the upcoming iPad Pro models would not include a headphone jack. iPhone models have not offered a headset connector since iPhone 7, with Apple instead inviting customers to use Bluetooth headsets like AirPods or Lightning-based solutions.
The information shared on Slashleaks is probably from a case manager, and because it is supported by data retrieved from other sources, it may be correct. Apart from the dimensions of the new iPad Pro models, the infos also confirm the presence of a new Smart Connector on the back of the two tablets.
Other 2018 iPad Pro rumors suggest that the device will have a USB C port instead of a lightning port, a faster A12X chip, and support for a second generation Apple pencil.
It's not clear when the new iPad Pro models will be announced, but their debut will probably be soon. We expect Apple to hold an event at a time in October, with the end of October appearing as the most likely option.
