Bose Frames Tempo can still work as open-ear workout sunglasses, but Bose no longer sells Bose Frames on its US website. In 2026, most buyers will be considering used units or old stock. That changes the decision: battery age, the proprietary product ecosystem, replacement parts, seller legitimacy and return rights matter as much as the original specifications.

This is a specification-based assessment, not a claim that we performed a long-term test. Bose’s US Frames page says the product family is no longer available for purchase there, but Bose continues to support existing owners. Availability and support can differ by country.
Bose Frames Tempo specifications
Bose introduced Frames Tempo in 2020 as the sports model in its audio-sunglasses line. The archived official product information lists:
- Open-ear audio: speakers in both temples direct sound toward the ears without an earbud sealing the canal.
- Battery: up to eight hours of music playback, with actual runtime dependent on volume, content and battery condition.
- Charging: USB-C, with an advertised charge time of up to one hour.
- Water resistance: IPX4 for sweat and splashes—not immersion, swimming or showering.
- Frame: TR-90 nylon; official listed weight about 49.9g.
- Included lenses: Mirrored Black polarized polycarbonate lenses; interchangeable Tempo lenses were also offered.
- Lens protection: Bose listed 99% UVA/UVB protection for the included lens.
- Bluetooth: version 5.1 with a listed range up to 30 feet under suitable conditions.
- Calls and controls: two microphones, a multifunction button, touch volume control and native voice-assistant access.
- Prescription use: Bose said Tempo was tested and approved for prescription lenses, subject to limitations and professional fitting.
Are Bose Frames Tempo good workout sunglasses?
The core idea still makes sense for some runners and cyclists: one device combines sun lenses with open-ear audio, leaving the ear canal unobstructed. Tempo also has three included nose-pad sizes, temple grips and spring hinges intended to improve sport fit. The interchangeable lens system offered different visible-light-transmission options for road and trail conditions.
However, open-ear does not mean risk-free. Music, calls and wind can still mask traffic, instructions or another athlete. Follow event rules and local laws, keep volume low enough for the setting, and stop playback where full attention is needed. No audio device substitutes for looking, signaling and choosing an appropriate route.
The biggest 2026 drawback: it is a discontinued retail product
Bose’s current US page explicitly says Bose Frames are no longer available for purchase on its website. Bose still provides support resources for owners, but discontinued retail availability creates several buyer risks:
- Battery aging: an unused-looking unit may have spent years in storage, and lithium-ion capacity degrades with time and use.
- Accessory supply: replacement lenses, nose pads or cases may be limited by region and seller.
- Warranty ambiguity: used or unauthorized-market purchases may not receive the original coverage.
- Counterfeit risk: Bose warns that counterfeit wearable-audio products, including Frames, exist.
- Software longevity: the Bose app currently lists Frames Tempo as supported, but future app or operating-system compatibility cannot be guaranteed indefinitely.
Do not pay the original launch price simply because a listing calls the unit “rare.” Compare the price with current open-ear headphones plus ordinary sport sunglasses, which may be easier to repair or replace independently.
Used Bose Frames Tempo inspection checklist
- Confirm the exact model. Tempo is the sport frame; Tenor, Soprano, Alto and Rondo have different fit, charging and water-resistance specifications.
- Request the serial number and proof of purchase. Use Bose support to check authenticity or support eligibility where possible.
- Test a full charge. Stream audio at a repeatable volume and measure runtime rather than accepting an “eight-hour” claim copied from new-product specifications.
- Inspect the USB-C port. Look for corrosion, looseness or debris and confirm reliable charging.
- Pair it before the return period ends. Test audio on both sides, buttons, touch volume, calls and the Bose app.
- Check the frame and hinges. Look for cracks, whitening, looseness and repairs near the electronics.
- Inspect every lens edge. Confirm secure installation and check the main visual area for scratches or coating damage.
- Verify included nose pads and case. Missing fit parts can make the frame unstable during a workout.
- Read the seller’s return terms. A short functional test is essential for an aging electronic wearable.
Fit considerations for running and cycling
At roughly 50g, Tempo is heavier than many conventional sport sunglasses. The weight includes the speakers and battery in the temples. That may feel stable on one face and pressure-heavy on another. Test the frame with the exact helmet, cap or visor you use, and check whether the thicker temples interfere with helmet retention hardware.
The supplied nose-pad sizes help, but they do not make one frame universal. Shake your head, look over each shoulder and assume your normal aero or running posture. Make sure the lens does not touch the cheeks, the temples do not lift the helmet, and the frame does not slide with sweat.
Water resistance: suitable for sweat, not swimming
IPX4 means protection from splashing water under the rating’s test conditions. Bose’s owner guide says Frames Tempo are designed for sweat and weather resistance against drops, but must not be submerged, worn swimming or used in the shower. The guide also notes that water resistance is not permanent and may decrease with normal wear.
That makes Tempo unsuitable for the swim leg of a triathlon. Store it securely in transition, keep the charging port clean and dry, and allow the frame to dry before charging. Salt, sunscreen and sweat residue should be handled according to Bose’s cleaning instructions rather than with household solvents.
Audio tradeoffs
Open-ear speakers preserve physical openness around the ear, but they do not produce the same isolation or bass response as sealed headphones. Wind noise can compete with speech and music on a bike. Raising volume to overcome wind undercuts the situational-awareness benefit and may increase sound leakage to nearby people.
Calls are possible through the dual-microphone system, but microphone performance depends on wind and surroundings. Treat call quality and privacy as things to test, not guaranteed outcomes.
Better alternatives in 2026
The most flexible alternative is to separate the two jobs: current sport sunglasses plus a current open-ear audio product. That lets you replace damaged lenses or a worn battery without replacing both systems. It also gives you more control over frame fit, lens category and nighttime use.
Choose Bose Frames Tempo only if the combined design is specifically valuable, the unit passes a battery and fit test, and the price reflects discontinued-product risk. For cold outdoor sessions, eyewear is only one part of comfort; our winter running sock guide explains how shoe volume and moisture change cold-weather choices.
Verdict: are Bose Frames Tempo worth buying?
For an existing owner with a healthy battery, Frames Tempo remains a capable open-ear sport wearable with USB-C charging, IPX4 splash resistance, interchangeable lenses and up to eight hours of advertised playback. For a new buyer in 2026, it is a conditional used-product purchase—not a default workout-sunglasses recommendation. Buy only with authentication, a functional return window, verified battery life and a fit test with your helmet.
