Apple removed the standard headphone jack in the iPhone 7 in favor of wireless headphones or headphones that plug into the Lightning port. Previously, users had reported a bug that caused a loss in mobile connectivity after disabling Airplane Mode on the newly launched handsets.

Initially noticed by Stephen Hackett of 512 Pixels, the smartphone appears to make a cicada-like sound.
In addition, AppleInsider reports that other iPhone 7 users are experiencing trouble finding service after switching their phones back to a cellular network after being on Airplane Mode. “It seems to get worse if the iPhone is under load, and can be heard while the phone is sitting on a table”.
Additionally, the problem seems to prevail in the iPhone 7 Plus. Apple has not yet responded. At all. The problem is so severe that Apple has to warn buyers about it before they purchase one. At present, the “tendency” of iPhone 7 and 7 Plus to hiss at their users is the center of attention. It’s possible that this sound is a “coil whine”.
Wherever you find Jet Black written on Apple’s site, there’s going to be a footnote that explains the phone will scratch easily, and you might need a special case to keep it in pristine condition.

On Twitter, Hackett wrote that Apple told him he could exchange his phone (the issue with doing that, however, is extremely limited stock), so there’s precedent for getting a new phone if you’re willing to wait for it. What’s more, the iPhones apparently continue to function despite the hissing sound. Moreover, iMore said there is nothing to worry about the noise because numerous devices produce noises during heavy processing activities. iMore is a known technology website.
