At the heart of the QuietComfort Ultra Earbuds is CustomTune technology, a breakthrough system that adapts sound and noise cancellation to the unique shape of the listener's ears. By calibrating in real time, these earbuds create a truly personalized listening experience, ensuring that music, podcasts, and calls sound balanced and clear no matter who is wearing them. This feature elevates the Ultra Earbuds above most competitors, offering a level of customization rarely seen in consumer audio.
They were both well received and proved popular with buyers, perhaps helped by their quirky yet super-comfy square shape. Still, many reviewers-myself included-noted that they seemed to lack features like advanced codecs, wear sensors, and customizable controls that came standard on similarly priced alternatives from the big brands. The bigger issue, however, was that the Between 3ANC's noise canceling and sound quality fell short.
When it comes to cutting out annoying outside noise, there is no brand in history that has denatured more decibels than Bose. The pioneers of noise-canceling haven't been without challengers in recent years, including Sony, Apple, and others, but Bose has maintained the crown for generation after generation. Perhaps no product showcases this iterative talent more than its latest earbuds, the QuietComfort Ultra 2.
When the AirPods battery runs out, simply dock them into the charging cable slot and connect them to the phone with the USB-C cable.
