The availability of Apple's wireless headphones, called AirPods, is delayed as the company is reportedly experiencing problems in getting the audio from both the earpieces at the same time.
According to Fortune, "technology problems with how the earpieces receive wireless signals via Bluetooth are causing delay."
Apple launched AirPods along with the iPhone 7 in September this year as a replacement for conventional earphones that require a headphone jack.
The company launched iPhone 7 without the headphone jack, however, consumers can still use wired earphones, but can be done by using a dongle to connect them via lighting port.
"The original plan was to ship the AirPods in October, but Apple decided to delay the earphones that month without giving a reason," the report added.
