a bit recently. I think I paid $300 for them. They're now $250.
They're not small, but the sound quality and active noise cancellation is fantastic. I've gone through 2 pairs of Samsung galaxy buds, a set of Pixel buds, a pair of beats earbuds, some Sony earbuds that were rated as the best noise cancelling earbuds on earth, and a cheap pair of Jlab buds. The Bose are far and away the best of the bunch.
The Sony earbuds were really good, but they were extremely bulky, even more so than the Bose earbuds, and the fit hurt my ears after extended use. The Samsung Galaxy buds are several tiers down in quality.
