Just over a month has passed since @MysteryLupin leaked details of forthcoming Bose headphone and earbud refreshes. To recap, the leaker revealed that Bose had created 'Diamond' versions of the QuietComfort Ultra Headphones and Ultra Open Earbuds (curr. $299 on Amazon). Additionally, @MysteryLupin highlighted a Lunar Blue version of the former and a Moonstone Blue version of the latter.

Now, Bose has introduced Diamond 60th Editions of not just theQuietComfort Ultra HeadphonesandUltra Open Earbudsbut also the QuietComfort Ultra Earbuds. As their names suggest, the Diamond 60th Editions celebrate Bose's 60th 'diamond' anniversary. Fundamentally, the refreshes contain the same hardware as the regularQuietComfort Ultra Headphones,Ultra Open Earbudsand QuietComfort Ultra Earbuds.

Thus, Bose continues to charge $299 for each pair of earbuds and $429 for itsQuietComfort Ultra Headphones. With that being said, it is running a 'Bose Diamond Anniversary' offer until September 15, during which it will take 10% off when purchasing all Diamond 60th Edition products. Incidentally, the Lunar Blue and Moonstone Blue editions of theQuietComfort Ultra HeadphonesandUltra Open Earbuds, respectively, remain unreleased. Presumably, these will land later this year, although it remains unclear when that will occur.
