BENGALURU — Apple on Monday unveiled the second generation of its premium AirPods Max over-ear headphones at US$549 (around 17,700 Thai baht), more than five years after the first version's launch. The update marks Apple's first major refresh of the over-ear headphones since their 2020 debut, as the company adds new features and improved noise cancellation to compete more aggressively in the premium headphones market. Upgrades to the AirPods Max 2 include better active noise cancellation, an improved microphone system and a range of new features including Adaptive Audio, Conversation Awareness and Live Translation. Live translation, first introduced on the AirPods Pro 3 in September, enables users to translate in-person conversations across languages using Apple Intelligence, the company's artificial intelligence platform. AirPods Max 2 also supports high-resolution lossless audio when connected via USB-C, targeting music creators and professional users who require higher fidelity audio, Apple said.
