Bose Sport Open Earbuds (2026), Black review

The 2026 Bose Sport Open Earbuds are open cuff-style wireless earbuds with a flexible C-arm that sits around the ear rather than sealing the ear canal. Bose's current Black US listing is the assessed finish. Its published combination is notably activity-oriented: IP54, a wireless-charging case, seven hours of stated playback per charge, and up to 22 more hours stored in the case. These are manufacturer claims; this review is not a workout, fit, sound, call, water or battery test.

There is an important identity trap: Bose also sold a different product called Sport Open Earbuds from 2021 to 2023. That earlier model has a rigid over-ear hook, one audio device at a time, an IPX4 claim and a stationary charging base. This review covers the 2026 silicone cuff and wireless case only. Check the year and image before buying.

Open design, not a sealed workout bud

Bose describes this as a completely open design and says it does not offer active noise cancellation. Sound is directed toward the ear while the ear remains uncovered; Bose's press material distinguishes its air-delivered OpenAudio from bone conduction. That may be attractive for runs or gym sessions where you want ambient sound to remain available, but an open earbud cannot provide the passive seal of a tip-based model. Do not treat it as hearing protection or as a guarantee that you will notice every hazard. Sound leakage and awareness depend on volume and surroundings.

The 2026 cuff is soft silicone and has tactile physical buttons, according to Bose's launch material. Those are genuine design differences from the older Sport Open's contoured hook and button layout. The product page identifies fit as a light flex grip; whether a cuff is comfortable or stays put on an individual ear is not established by a photograph or the maker's stability description. If your priority is an open design, the key question is not a nominal fit label but whether this around-ear contact point works for you. Use a seller with a return path that gives you a practical chance to assess fit.

Runtime and case charging

Bose lists up to seven hours on a charge and up to 22 additional hours in the charging case. Its launch announcement states that Auto Volume can reduce earbud playback to about 3.9 hours. Treat the shorter figure as the more relevant published ceiling if automatic volume adjustment is important to your routine; neither figure is a guaranteed outcome for calls, high volume, temperature or aging batteries. A ten-minute quick charge is advertised to provide up to 1.8 hours. The case supports wireless charging as well as a USB-C port, giving a choice between a cable and a compatible charging pad.

The 2026 model's product-level IP54 rating is different from the questionnaire's narrow IPX4-earbuds-only choice, so it is not treated as an exact match there. The rating covers the product as described by Bose; it is not a waterproof or swimming claim. For sweat and rain, check the current manual's cleaning and drying instructions, especially before docking or wireless charging. The case's charging features should not be read as permission to charge wet earbuds.

Connectivity and controls

Bose's 2026 announcement specifies Bluetooth Core 5.4, Classic Audio SBC and AAC, Google Fast Pair and multipoint with two devices. Multipoint is for switching between connected sources, not for playing two sources at once. The manufacturer material presents these capabilities but does not establish that every codec, feature and connection mode can coexist in every usage configuration, so the assessment treats ordinary SBC/AAC playback and two-source multipoint separately. The physical buttons could be useful when fingers are sweaty, but I have not handled them or judged their tactile response.

On paper, the 2026 Sport Open is most relevant to someone seeking an open cuff for movement, a higher published product water/dust rating than a buds-only IPX4 claim, and wireless charging. The drawbacks are the same design's boundaries: no ANC, no sealed isolation, a fit that must be judged on your own ear, and shorter advertised time when Auto Volume is active. An older 2021 Sport Open offer may be mislabeled similarly, so verify its soft cuff and wireless charging case rather than relying on the shared product name.

Checks before purchase

Confirm the exact 2026 Black SKU and the current C-arm silhouette. Check whether the box includes the intended charging case, cable, and documentation, and whether your charging setup is USB-C or a compatible wireless pad. Confirm fit and control preferences with the seller's return policy. If you need cancellation, a sealed fit, or a product where the case is explicitly IP-rated, this open design is not a shortcut around those requirements. For a more immersive open cuff, compare Ultra Open 2, but review its different IPX4 earbuds-only protection and feature-dependent runtime. For the historic 2021 Sport Open, see the separate assessment rather than assuming the 2026 features carried over.

These are the two non-Black finishes shown on Bose's US product page. The photographs identify the 2026 flexible C-arm cuff and do not represent the unrelated 2021 earhook model. The review and capability assessment above remain anchored to the exact Black configuration.
