Bose has announced a new version of the earbuds that helped kick off the industry trend of clip-on wireless audio nearly two and a half years ago, revealing the Ultra Open Earbuds second generation alongside a cheaper sport-oriented sibling. The announcement positions Bose to defend the category it seeded against a wave of imitators now crowding the open-ear market. The second-generation Ultra Open Earbuds will be available for preorder on September 19 for 299 dollars, with availability starting October 1 in black, white smoke, cherry chocolate, olive green and sky pink. The new Bose Sport Open Earbuds share the same preorder and availability dates but undercut the flagship by 100 dollars at 199, in black, white smoke and eucalyptus green. ## More Bass, More Hours, A Case That Stands The design of the flagship remains mostly the same aside from aesthetic refinements, including a new beveled finish on each earbud's metal cap. As with the original, the buds clip to the outer ear with a transducer that directs audio into the ear canal with what Bose claims is minimal sound leakage, and there is still no noise cancellation, because these are built to do the opposite: let you hear the world while you listen. Under the skin, the changes are substantive. A new driver delivers higher volume with automatic adjustments and deeper bass, while a new Cinema Mode simulates a wider, more immersive soundstage using Bose's TrueSpatial technology while keeping dialogue clear and centered. Battery life with the buds alone rises to nine hours from seven, with an additional 19.5 hours from a redesigned charging case that can now stand upright for use on a wireless charger. ## A Sport Model Built To Stay Put The Sport Open Earbuds take the same clip approach but target a different failure mode: staying on your head. They feature a thinner cuff with a soft silicone matte finish providing more grip, and Bose says they will remain secure through head shakes, cartwheels and running. Automatic volume adjustments adapt to ambient noise so workouts do not drown out podcasts, and the customizable shortcut button on the end of each battery barrel gains an added bumpy texture that makes the controls easier to find by touch mid-exercise. Battery life is rated at seven hours of playback plus 22 additional hours with the wireless charging case. The two-model strategy marks a maturing phase for the open-ear category Bose effectively created. At 199 dollars, the Sport version gives casual buyers and gym-goers an accessible entry point, while the 299 second-generation flagship courts the buyers who want the company's best sound and spatial features. For a company whose noise-cancelling headphones defined a previous era, the pivot toward earbuds that deliberately let noise in is a bet on how people actually wear audio now: on runs, in offices, and everywhere that full sealed-ear isolation is impractical or unsafe. Preorders open September 19, and October 1 will show whether the category's originator can hold the lead it invented. ## Why The Open-Ear Category Is Growing The open-ear format solves problems that sealed in-ear buds never quite managed. Office workers need to hear a colleague approach. Runners need traffic. Call-heavy days become unbearable with a plug sealing each canal for eight hours. Clip-on designs preserve ambient hearing without the wind noise and awkwardness of traditional bone-conduction headsets, which is why nearly every major audio brand now sells one, two and a half years after Bose's original Ultra Open debuted the template. The tradeoffs remain real: without a seal, bass response is inherently limited and sound leakage rises with volume, which is why Bose's marketing for the second generation leans on the new driver's deeper bass and its claims of minimal spill. The extra two hours of battery also addresses the format's practical ceiling, since open designs are typically worn longer than noise-cancelling ones. ## The Price Ladder Takes Shape Bose's two-tier launch also clarifies how the category is segmenting. The 199 dollar Sport model competes directly with budget open-ear buds from budget brands that have proliferated on marketplace listings, while the 299 dollar second-generation Ultra holds the premium ground against rivals from the biggest names in consumer audio. Both models hit shelves October 1, comfortably ahead of the holiday quarter that will decide which design language, and which company's interpretation of open audio, becomes the default on wish lists. For Bose, the announcement is a statement that the company intends to lead the market it started rather than watch imitators commoditize it; for shoppers, the 100 dollar spread between the two models makes the entry cost of the format's most polished version lower than it has ever been. One caveat for buyers weighing the preorder: neither model includes wireless charging of the buds themselves outside the redesigned case, and color options differ between tiers, so the choice is not purely about price. But with preorders opening September 19, the window to be first in line for either ends quickly.
