Speculation has been ramping up around when we’ll see the next generation of AirPods, with some reports claiming we’ll see a new model with an upgraded wireless chip and “Hey Siri” support for calling up Siri without the need to physically tap the headphones as early as this year. But 9to5Mac reports Barclays thinks Apple could wait until 2019 to reveal new AirPods with improved noise-canceling features. The analysts claim we’ll see “design changes and improvements” over current AirPods, but earbuds using physical analog methods will have a tough time competing with electronic active noise cancellation now common in over-the-ear headphones. The previous report from Bloomberg speculated that Apple could be adding waterproofing to the AirPods by 2019, so it’s possible that the noise reduction claim is a happy coincidence created by the better seal.
