Most people weren't too surprised when Apple revealed that the iPhone 7 wouldn't come with a headphone jack. Rumors and speculation over the decision had been circulating for months, but a lot of fans were still angry about it. Apple, however, thinks it was the right choice, and the company may eventually do the same thing with the MacBook Pro.

MacRumors was the first to notice that Apple has been sending out surveys to MacBook Pro users asking about a number of features found on the laptop. But the question that sticks out the most is: "Do you ever use the headphone port on your MacBook Pro with Retina display?"

Other questions ask how satisfied users are with their laptop's battery life, how often they use specific ports, and what method they use to upload photos from a digital camera to a MacBook.

Apple is expected to release its refreshed MacBook Pro series next month. Leaked images of the laptop's chassis suggest it will include a 3.5mm headphone jack, along with four USB Type-C ports. It also shows an absence of an SD card slot, HDMI port, USB-A port, and MagSafe connection.

Assuming the images are accurate, it seems that it could be a while before Apple decides the MacBook Pro should follow in the iPhone's footsteps and abandon the 50-year-old 3.5 mm connector. Exactly how long could depend on the responses it receives from the survey.

Some other rumored changes expected to arrive on the refreshed MacBook Pro include a slimmer design, flatter keyboard, and an OLED touch panel.
