On Thursday, Bose unveiled its next-gen premium wireless earbuds. The latest QuietComfort Ultra Earbuds have enhanced adaptive noise cancellation, thanks to AI. Among their other upgrades over the originals are boosted call quality and wireless charging.
Since AI is the tech world's obsession, it's no surprise that Bose is jumping on that bandwagon. Here, the company uses it to improve adaptive noise cancellation. AI algorithms in the new model can smooth out sudden spikes in background noise while using aware mode. (That's the feature that lets you hear your surroundings while listening to music.) So, for example, the ANC should respond more quickly to a suddenly passing train or siren. In theory, that means fewer distractions from your music.
AI is also behind improved call quality in the second-gen QuietComfort Ultra Earbuds. Bose claims that its noise suppression system improves voice pickup and overall quality.
The new model supports wireless charging natively. The first-gen QC Ultra Earbuds only offered it in a roundabout way. You had to buy a $50 silicone cover for the case, which wasn't the most elegant solution.
The rest of the 2025 model's upgrades are subtler. Their ear tips now include a built-in earwax filter. That should make it easier to clean them and avoid sound degradation over time. You can also turn off the earbuds' capacitive touch controls in the app. The inability to do that was a common complaint about the 2023 originals. (They'll receive an update later this year that adds the same functionality.)
The second-gen Bose QC Ultra Earbuds retail for the same $299 as their predecessors. They'll be available in black, white smoke and deep plum. Later this summer, the company will start pre-orders and provide a release date.
Alongside the earbuds, Bose announced two new Bluetooth speakers. The SoundLink Plus is a mid-range one, sitting between the SoundLink Flex and Max. The company's tagline for the speaker sums up the niche it wants to fill: "big enough to bring the bass but portable enough to take on the go."
The SoundLink Plus has one subwoofer, a tweeter and four passive radiators. It also includes an automatic tuning system called Active EQ. Bose says it adjusts its frequency response to match an optimal sound curve. It weighs 3.29 lbs. It supports Bluetooth Core 5.4.
The speaker supports up to 20 hours of playback. In a nice touch, you can use its USB-C port to charge your phone and other devices.
The SoundLink Plus costs $269. If you're looking to grab one, you won't have to wait long. Pre-orders open today, ahead of a June 26 launch. It will be available in black, blue dusk and citrus yellow. (The latter won't be available to pre-order until June 18.) SoundLink Micro (second-gen) (Bose)
Finally, Bose is rolling out a second-gen version of the SoundLink Micro. The speaker is still small — just slightly less so than the first model. (The second-gen Micro measures 4.06 x 4.06 x 1.54 inches.) But in exchange, you get much longer battery life. Bose says the new speaker lasts up to 12 hours, an increase from six hours in its predecessor.
The SoundLink Micro also includes some modernizations. First, it now works with the Bose app. The speaker also ditches the micro-USB charging from its predecessor in favor of USB-C.
Elsewhere, it adds the same Active EQ and Bluetooth Core 5.4 support in its mid-range sibling. The company claims that the speaker plays back sounds more clearly at higher frequencies. (And it does so without muddying bass.) It also has a removable nylon strap. This should be handy for attaching the speaker to bags, bikes, shower heads and the like.
The Bose SoundLink Micro will be available in black and blue dusk. It costs $129. The company will provide specific launch info later this summer.
