When Apple (AAPL - Get Report) first announced its new wireless "AirPods" headphones in September during an event, the iPhone giant touted the new product as forging the path toward an inevitably wireless future.
But three months since unveiling the $159 headphones at its keynote September event, Apple still has yet to make AirPods available to customers. The company's landing page for the product still sits stagnant, stating the pods are "currently unavailable."
Now nearly two weeks into December, Apple is running out of time to launch the headphones during the holiday shopping season.
The delay in shipping the pods could be because Apple, which did not return a request for comment, is still wrestling with the technology. Sources told the Wall Street Journal that the Cupertino, Calif.-based company is having trouble syncing wireless signals to both pods.
In other wireless headsets, a digital signal is sent to only one of the pieces before being transmitted to the other. Apple's new product, however, operates by receiving two independent signals: one to each ear piece. But the company has struggled getting the two signals to send at precisely the same time in order to eliminate distortion, sources told the Journal.
The company also has yet to determine what to do if customers lose just one of the pods, or if the battery on one but not both of them dies.
"We need a little more time before AirPods are ready for our customers," an Apple spokesperson told the Journal. "We don't believe in shipping a product before it's ready."
At the end of November, Apple CEO Tim Cook reportedly told a customer that the company was finalizing the product, and the customer could expect AirPods to ship in the next few weeks ahead of the holiday season, according to AppleInsider.
The other products that Apple unveiled during the September keynote event -- including the Apple Watch series 2 and the iPhone 7 and 7 Plus -- have all already been made available for purchase.
Since first becoming available, the iPhone 7 has been seeing "higher than expected demand," according to IDC data. Piper Jaffray in a recent analyst note dubbed it as the number one requested gift of the holiday season, ahead of Alphabet's (GOOGL - Get Report) Pixel phone.
Cook also told Reuters this week that sales for the company's smartwatches hit record highs during the first week of holiday shopping. "Our data shows that Apple Watch is doing great and looks to be one of the most popular holiday gifts this year," Cook said.
But as Apple's other new products gain steam, the AirPods are still sitting on the bench.
Recode senior retail editor Lauren Goode said recently on CNBC's "Squawk Alley" that Apple is "missing out" on significant holiday sales this year due to the delay of the AirPod. She noted that Bluetooth headsets are "hot gadgets" this year.
Apple might be behind schedule on delivering its latest hot product, but the stock was still up about 2% to $114.14 on Friday. Apple shares have risen about 8.5% year-to-date.
