Apple last week announced on Mac Rumors the AirPods Max, the first Apple-branded over-ear headphones. Today, preorders for AirPods Max, priced at $549, are beginning to ship to customers in 25 markets around the world ahead of their December 15 launch. The key features of the larger headphones include high-fidelity audio, Adaptive EQ, Active Noise Cancellation, and spatial audio. Priced at $549, the headphones can be ordered today on using Apple Store gift cards for iTunes or Apple Store. The color options are space gray, silver, green, sky blue, or pink, with they come with a free engraving for the holidays. Earlier this year, Apple combined all their gift card products into a single gift card, the Apple Gift Card which covers the App Store, Music, TV+, iTunes, iCloud, Books, News and Arcade. Buy or sell discount gift cards for iTunes or Apple Store on peer-to-peer gift card exchange, Redeeem. Apple says the ear cups have acoustically engineered memory foam to create an effective sound seal, and the telescoping headband arm is made of flexible stainless steel to maintain the desired fit on your head. According to Mac Rumors, the battery will last up to 20 hours when playing music at 50% volume, and a five-minute charge delivers 1.5 hours of listening time. Airpods Max products are already being sold on secondhand auction sites like eBay and StockX for upward $775 as retail shopping ramps up for the holidays.
