Introduction

Open‑ear earbuds occupy a narrow but growing corner of the headphone market: they deliver audio to the wearer while leaving ears physically unobstructed. That combination appeals to outdoor athletes, urban commuters and anyone who prioritizes situational awareness. Bose has been a visible force in that niche since introducing its clip‑on, cuff‑style open‑ear designs. The Ultra Open Earbuds, released in 2024, set a high bar for fit and sound, albeit at a premium price.

Now Bose is expanding its open‑ear lineup with two new models: a direct successor that aims to remedy the format’s biggest compromises, and a sport‑focused variant that trades some refinements for ruggedness and a lower price. The product pair reflects a broader market move: manufacturers are refining open‑ear form factors to be louder, more durable and more affordable. What follows is a detailed look at what’s new, how these earbuds differ from one another and where they fit in the hands (and ears) of real users.

Why open‑ear earbuds still matter

Most wireless earbud designs seal the ear canal. That seal improves bass response and passive isolation, and enables features like active noise cancellation. Open‑ear devices take the opposite approach: speakers sit outside or at the entrance of the ear, and the ear remains acoustically open to ambient sound.

That arrangement delivers two practical benefits. First, safety: runners, cyclists and urban walkers keep auditory access to traffic, announcements and other cues. Second, convenience: users can hold conversations or stay aware of surroundings without removing their audio device. These strengths explain why coaches, outdoor workers and commuters continue to choose open‑ear options despite certain tradeoffs.

Open‑ear designs do face technical hurdles. Sound energy leaks into the environment, reducing perceived loudness and limiting bass impact. Microphone performance for calls can be compromised by wind and ambient noise. Fit stability is also a sticking point: without in‑ear anchors, earbuds must rely on clamping or cuff systems to remain secure during vigorous motion. Bose’s new models address each of these problems in different ways.

What Bose improved with the Ultra Open Earbuds (2nd Gen)

The Ultra Open Earbuds (2nd Gen) are the more direct evolution of Bose’s original open‑ear concept. The company kept the cuff‑shaped design that users found comfortable and intuitive, while concentrating on three core weaknesses of the format: volume, call clarity and battery life.

• Louder output: Open‑ear speakers struggle to generate the same façade of volume delivered by sealed earbuds. Bose says the new Ultra delivers significantly higher output than the original models, a welcome correction for users who found themselves turning the volume to uncomfortable levels in noisy environments. Louder audio also improves intelligibility for spoken content — podcasts, audiobooks and coaching cues during workouts.
• Improved call performance: Microphone arrays and signal processing have to fight background noise, especially outdoors. Bose claims better call quality on the Ultra 2nd Gen, which suggests updated mics and refinements to voice‑isolation processing. For many buyers, call performance is decisive; a great open‑ear listening experience falls short if phone calls come through thin or drowned in wind noise.
• Longer battery life and charging upgrades: Battery life is a sticking point in portable audio. Bose reports longer run time on the Ultra 2nd Gen. The charging case is also redesigned with an upscale metallic cap and a beveled finish. It now supports wireless charging and can stand upright, which simplifies bedside or gym‑bag placement and feels like a small but thoughtful ergonomics improvement.

These changes mostly follow from practical use cases. A runner who needs audible coaching cues will appreciate louder and clearer audio; a hybrid worker who wants to stay alert to colleagues while taking calls will welcome more reliable voice pickup; anyone on the move benefits from a charging case that charges wirelessly and stands on its base.

Design and fit: subtle evolution, familiar feel

Bose’s open‑ear earbuds rely on a cuff that clips to the outside of the ear. Early adopters praised that concept for comfort and repeatable placement. The Ultra 2nd Gen keeps the cuff but refines details.

Fit remains a balance between pressure and security. The cuff‑style approach avoids the canal‑blocking pressure that some users find uncomfortable on long wearing sessions. It also keeps the earpiece visible for quick adjustments. Bose’s design continues to lean on soft silicone hinges for a flexible, earring‑like clip. That material choice does two things: it reduces pressure points and creates enough compliance to conform to a range of ear shapes.

The new finishes take design seriously. Bose offers five colorways across the Ultra: classic black and white smoke plus Cherry Chocolate, Olive Green and Sky Pink. Color plays a surprisingly important role in wearable audio; consumers increasingly expect options that reflect personal style rather than a single corporate aesthetic. The updated metallic cap on the charging case gives the product a premium look that matches the $299 positioning.

Fit matters most during movement. The Ultra’s cuff approach is intended to hold steady while still being comfortable during longer sessions. For people whose primary activity is walking or moderate jogging, that balance usually succeeds. For more aggressive motion—trail running, obstacle courses, high‑impact sports—Bose offers the Sport variant described next.

The Sport Open Earbuds: engineered for motion

Bose positions the Sport Open Earbuds as a more rugged, activity‑first alternative to the Ultra line. Two elements define the Sport model: a new curved C‑arm cuff for added security, and IP54‑rated resistance to sweat and dust.

• C‑arm cuff design: The Sport’s hinge changes geometry. Bose calls it a C‑arm, a more pronounced curve intended to lock the earbud into place during vigorous activity. The company claims the design keeps earbuds secure through “headshakes, cartwheels and other activities.” That’s a bold way to communicate confidence in fit. For athletes who need their gear to stay put through sprints, agility drills and dynamic movement, cuff geometry can be the difference between a watchful training session and repeated interruptions to reset earwear.
• IP54 rating: IP54 provides protection against dust ingress sufficient for everyday outdoor use and defense against splashing water from any direction. It does not make the earbuds fully waterproof or suitable for submersion. For runners who train in drizzle, gymgoers who sweat heavily, or anyone who regularly faces dust and grit, the IP54 rating reduces anxiety about ruinous contact with the elements.
• A lower price point: Bose priced the Sport Open Earbuds at $199, making them $100 less than the Ultra 2nd Gen. That positions the Sport model against an expanding set of mid‑range options in the market. The lower price, combined with sport‑oriented durability, is likely to broaden the appeal of Bose’s open‑ear ecosystem.

Physically, the Sport earbuds look distinct from the Ultra: the cuff is more curved, and the overall silhouette leans athletic. Beyond fit and protection, the Sport model’s tuning is likely optimized for clear midrange and vocal presentation rather than weighty low end—a reasonable tradeoff for runners who prioritize cues and speech intelligibility.

Audio tradeoffs and the problem Bose aimed to solve

Open‑ear formats inherently compromise on bass and isolation. Those compromises create predictable problems: music can lack punch; perceived loudness suffers; and environmental noise competes with the listening signal.

Bose tackled the perceived loudness issue head‑on with the Ultra 2nd Gen, promising a “considerably louder” output than the originals. That matters for a few user groups:

• Outdoor athletes who need to hear tempo cues or interval instructions across busy streets or noisy parks. Louder absolute output reduces the temptation to push volume beyond safe listening levels.
• Podcast and audiobook listeners who need speech clarity in ambient environments. Improved volume helps spoken content cut through without resorting to aggressive equalization.
• Users who desire richer listening when ambient noise is minimal—say, in the early morning on quiet streets.

Louder volume alone does not solve every problem. Open‑ear designs still leak acoustic energy into the environment, making bass less present. Bose’s claim that the Ultra 2nd Gen “sounds better” suggests tuning and driver improvements that compensate for that leakage—improvements that could include better low‑frequency driver response, DSP‑based bass enhancement, or just more efficient acoustic coupling to the ear. The company also reports better call quality, implying upgraded microphones and improved processing.

For buyers who place a premium on bass and isolation—commuters on noisy trains, studio listeners, audiophiles—sealed in‑ear or over‑ear designs will remain the better option. For those who prize awareness and comfort, the tradeoffs of the open‑ear approach now look more manageable.

Charging case: a small design detail with outsized impact

Charging cases have become a signature expression of a brand’s product thinking. Bose’s Ultra 2nd Gen charging case gains features that feel targeted to everyday use rather than just spec sheets.

• Wireless charging: The addition of wireless charging removes cable reliance for overnight top‑ups or quick gym charges. Users with wireless charging pads already in their environments find a small but cumulative convenience.
• Upright standing: Having the case stand upright is a practical change. It occupies less horizontal surface area on a crowded bedside table or gym locker shelf. The upright stance also reduces the risk of the case rolling off a surface and adds a sense of presence when placed on a nightstand.
• Metallic cap and beveled finish: Aesthetic upgrades matter to buyers in the $300 range. Premium finishes differentiate products in a crowded market and justify price points when design and materials feel deliberate.

Beyond these enhancements, the Sport model’s case was not described in detail in the source material. Given its price tier, it will likely be a function‑forward shell that prioritizes protection and portability.

Price, colors, availability: how Bose positions the new lineup

Bose’s pricing signals how it expects customers to choose between the two models.

• Ultra Open Earbuds (2nd Gen): $299. Positioned as the flagship open‑ear experience, it aims at users who want the best possible audio and accessory experience that Bose can offer in this form factor.
• Sport Open Earbuds: $199. Positioned as a more rugged, price‑accessible option for athletes and active users. This price makes open‑ear technology more attainable for a wider audience.

Color options span classic and seasonal tones. Both models offer black and white smoke. The Sport model adds Eucalyptus Green, which aligns with outdoorsy aesthetics. The Ultra 2nd Gen broadens the palette with Cherry Chocolate, Olive Green and Sky Pink. The variety reflects a marketing shift in consumer audio toward personalization and lifestyle alignment.

Preorders open on September 19, with shipping starting October 1. Those timelines are useful for buyers planning fall training cycles or early holiday shopping.

Who each model is for — practical buying guidance

Choosing between the Ultra 2nd Gen and Sport Open Earbuds depends on use case, budget and aesthetic priorities.

• Choose the Ultra Open Earbuds (2nd Gen) if:
  • You prioritize the best possible open‑ear sound Bose offers.
  • Call quality and battery life are critical to your daily workflow.
  • You want premium case features like wireless charging and a metallic finish.
  • You value a broader color palette and premium styling.
• Choose the Sport Open Earbuds if:
  • You need a secure fit during high‑intensity workouts.
  • You frequently train in conditions where sweat and dust are concerns.
  • Price sensitivity matters; $199 better fits your budget.
  • You prefer a sportier, more rugged aesthetic.

Real‑life scenarios help clarify the difference. A cycling commuter who trains year‑round, runs interval sessions and cares about reliable, sweat‑resistant gear is a natural fit for the Sport model. A hybrid professional who takes calls, listens to music during walks and prefers a refined look and extra battery life will likely prefer the Ultra 2nd Gen.

Safety, awareness and legal considerations

Open‑ear earbuds promote awareness, but awareness is not a guarantee of safety. Ambient hearing does not make someone invulnerable to road hazards. Users who rely on open‑ear audio while bicycling or jogging must still practice defensive behaviors: obey traffic laws, use lights and reflectors at night, and prioritize visual scanning of intersections.

Additionally, local laws vary about earwear while operating vehicles or bicycles. Urban cyclists should confirm regional regulations regarding earphones while riding. Bose’s design choices support safer listening by leaving ears open, but responsible usage remains the user’s responsibility.

How these Bose models compare to other approaches

Open‑ear sound has several technical approaches. The main categories include cuff‑style open‑ear, bone‑conduction and traditional in‑ear/over‑ear designs.

• Cuff‑style open‑ear (what Bose uses): Speakers sit outside the ear and direct sound into the ear canal without sealing it. This approach balances comfort and awareness. Bose’s cuff design is well‑established and benefits from careful ergonomics.
• Bone‑conduction: Transmits vibration through the cheekbone to the inner ear. Bone‑conduction avoids plugging the ear canal and is often marketed for safety. The tradeoffs include different sound timbre, compromised bass, and potential issues with long listening sessions due to vibrations.
• In‑ear with transparency modes: Many sealed earbuds now include transparency or ambient modes that use microphones to let in outside sound. These emulate open‑ear awareness but still place a seal in the ear canal. They combine isolation when desired and awareness when needed, but they may not feel as natural for users who dislike ear canal pressure.

Bose’s latest releases target the cuff‑style advantage: natural awareness with improved audio and durability. The Ultra 2nd Gen's louder output aims to close the performance gap that has historically favored in‑ear and over‑ear models.

Potential drawbacks and unanswered questions

Bose’s announcements address several open‑ear limitations, but a few practical considerations remain.

• True bass response: Even with louder output and tuning tweaks, open‑ear designs cannot replicate the low‑frequency extension of sealed earbuds. Listeners who prioritize thumping bass or expansive soundstage may still prefer in‑ear or over‑ear models.
• Wind noise on calls: Outdoor wind is a perennial challenge for microphones. Bose reports improved call quality, but real‑world performance in gusty conditions will determine whether this is a substantive improvement.
• IP rating limits: IP54 provides protection against dust and splashes but does not render the earbuds submersible. Users who run in heavy downpours or engage in water sports should not assume full waterproofing.
• Fit variability: Ear geometries differ widely. The cuff approach is inclusive of many shapes but is not universal. Prospective buyers should test fit if possible or order from retailers with generous return policies.
• Battery specifics: Bose states longer battery life for the Ultra 2nd Gen but did not disclose precise run times in the information provided. Buyers who prioritize multi‑day battery endurance or long ultramarathon training sessions will want to verify the exact specifications as they become available.

Real‑world examples: how people might use them

Practical scenarios illuminate where these earbuds shine.

• Morning runner: A runner covering mixed urban roads needs to hear audio coaching and ambient traffic. The Sport Open Earbuds, with the C‑arm cuff and IP54 rating, stay secure and resist sweat during intense intervals.
• Urban courier: A cyclist making stops across a city requires situational awareness for traffic and announcements. The Ultra 2nd Gen’s louder output and improved call quality support safer navigation and clearer communications with dispatch.
• Office hybrid worker: Someone who alternates between focused desk work and walking meetings benefits from open‑ear listening to stay connected to colleagues while taking calls. The Ultra 2nd Gen’s improved call performance and wireless charging case add convenience.
• Outdoor fitness class instructor: Instructors who cue groups in parks need reliable speech clarity and the ability to hear surroundings. The Sport model’s secure fit and durability make it suitable for instructors who demonstrate movement and speak loudly.

These scenarios demonstrate that open‑ear earbuds are not a niche gadget but a practical toolset for many active lifestyles. Bose’s new models expand those use cases by addressing the format’s historical limitations.

Market context and why this matters for consumers

Open‑ear earbuds have been gaining momentum as manufacturers work to solve their key downsides. A wider range of options, particularly at multiple price tiers, benefits consumers by creating healthy competition. Pricing a sport‑focused model at $199 broadens access and invites comparison across brands. The Ultra 2nd Gen, priced at $299, reinforces that Bose intends to lead the premium segment of the open‑ear field.

For consumers, the most important metric will be real‑world performance: how much louder the Ultra 2nd Gen truly is, how durable the Sport model holds up under months of use, and whether call quality improvements are tangible in windy environments. Early adopters who value situational awareness, comfortable long‑wear sessions and the ability to take calls without removing their earbuds will likely find one of these models compelling.

Practical buying checklist

Before committing, evaluate these considerations:

• Try the fit: Cuff systems feel different from in‑ear picks. If possible, test a pair during dynamic movement.
• Consider your main use: If you need sweat resistance and fit security for intense workouts, lean toward the Sport. If call quality, battery life and premium finishes matter more, the Ultra 2nd Gen is the better bet.
• Think about environment: If you frequently train in heavy rain, IP54 will not be enough. For casual rain and sweat, it provides solid protection.
• Assess content type: Music with heavy bass will not reach the same depth as sealed earbuds. If your library is bass‑heavy electronic or hip‑hop, you may prefer in‑ear alternatives.
• Review return policy: Personal fit and comfort are highly individual. Choose a retailer or direct channel with a straightforward return window.

What to watch for in hands‑on reviews

Manufacturers’ claims are helpful, but independent hands‑on testing reveals practical performance. Look for reviewers who address:

• Measured and perceived loudness in decibels compared to the previous generation and competitors.
• Speech clarity for calls in diverse outdoor conditions, including windy streets.
• Battery test results: run time per charge and how much extra charge the case provides.
• Fit retention during sprinting, lateral movement, and accidental head shakes.
• Durability over time, particularly for the Sport model: does sweat or dust degrade hinge performance or finish?
• Comfort across long sessions — 60 to 120 minutes of continuous use.
• Latency with common devices for athletics (smartphones, GPS watches) if you listen to real‑time coaching or synchronized audio.

Independent tests will determine whether Bose’s claims translate to day‑to‑day advantages.

Final assessment

Bose’s twin release addresses two distinct sets of user needs with a clear strategy. The Ultra Open Earbuds (2nd Gen) refine the flagship experience—louder sound, better calls and a more premium case—while the Sport Open Earbuds bring durability and a competitive price to active users. Together they broaden the appeal of open‑ear audio beyond an enthusiast segment and reinforce Bose’s leadership in the cuff‑style open‑ear category.

The success of these models will hinge on real‑world performance: whether the Ultra’s volume improvements genuinely close the gap with sealed designs, and whether the Sport’s cuff can remain secure during high‑impact sessions. For buyers who prioritize awareness and comfort over sealed isolation, both products look like meaningful, practical choices.
