Apple's decision to remove the headphone port was already seen as controversial and now detractors have some additional ammo to fire at the company. Apparently numerous users have been experiencing problems with the Lightning EarPods on the new iPhones, where the volume control dongle stops working, so you can't adjust the volume, use Siri, or answer calls.

The glitch seems to happen randomly and is fixed by unplugging and re-plugging until the next time it happens. According to early reports, audio continues to play, you just can't control playback. Apple has acknowledged the problem and promised a software update.

Apple removed the standard headphone jack in the iPhone 7 in favor of wireless headphones or headphones that plug into the Lightning port. The company defended its decision, saying the move made space for an advanced Taptic Engine, bigger battery and better cameras. It also helped waterproofing the iPhone design by eliminating a key point of liquid ingress.

Although the new iPhone 7 and 7 Plus will certainly sell in huge numbers, things haven't been trouble-free since going on sale last week. Apart from the headphone issue, Some owners have reported hearing 'hissing' sounds from the device during heavy usage, although we'll reserve judgement on that until we get some hands on time with the device.

On other other side of the equation, the phone has also been praised for reportedly having the most color accurate display, at least according to the experts over at DisplayMate.
