Bose QuietComfort Ultra Earbuds (2nd Gen) + AirFly Pro 2 Set (Deep Plum / White) review

This is a current Bose U.S. bundle assessment, not a separate QuietComfort Ultra earbud generation. The captured Bose set page identifies bundle code SET-QCUE2-AFP2 and, in its selected configuration, Deep Plum QuietComfort Ultra Earbuds (2nd Gen) component QCUE2-HEADPHONEIN-DPPLM-WW plus one White AirFly Pro 2 transmitter AFPRO2-3_5MM-TRANSMITTER-WHT. The practical reason to consider the set is the supplied audio adapter, not a different sound or cancellation claim for the earbuds. This is a source-based assessment; it is not a hands-on test.

What the bundle changes—and what it does not

The earbuds retain the second-generation QCU2 design: sealed tips and stability bands, Quiet/Aware/Immersion listening modes, active noise cancellation, a USB-C and wireless-charging case, and the product family's stated Bluetooth and codec support. Bose also lists IPX4 for the earbuds but not for the charging case. The separate AirFly component creates another way to get audio into the earbuds: a wired 3.5 mm headphone output can feed the battery-powered transmitter, which then sends audio over Bluetooth. That may suit a seat-back or gym jack when a direct Bluetooth connection is unavailable, but it does not change the earbuds' wearing style or protect the case from water.

When AirFly Pro 2 is useful

Bose describes this set for places without Bluetooth and says the transmitter plugs into a headphone jack; Twelve South describes AirFly Pro 2 as a way to connect Bluetooth headphones to a standard headphone jack. The bundle therefore addresses a specific travel or equipment problem, rather than making the earbuds universally compatible with every audio socket. Check the source itself: a seat may have a different connector or may not provide the expected jack. Bose's page identifies the standard Pro 2 component, while Twelve South distinguishes its Deluxe package by listing an international airline adapter there. An adapter is not listed in the standard Pro 2 component contents reviewed here, so confirm the jack and any needed converter before travel.

Keep the two batteries separate

The two products have independent batteries and charging needs. Bose gives the earbuds an up-to-six-hour music maximum in Quiet mode with Immersive Audio off, and up to four hours with Immersive Audio on; its test conditions and the chosen settings matter. Twelve South describes AirFly Pro 2 as a 25-plus-hour battery product, while Bose uses an “up to 25 hours” qualifier. Those are separate component claims, not a combined 25-hour earbud listening session. The QCU2 charging case is wireless-charge capable and USB-C chargeable; AirFly has its own USB-C charging cable. A travel plan should include charging both pieces, not just the earbud case.

One included headphone pair, with an optional sharing use

Bose and Twelve South describe AirFly Pro 2 as able to connect two sets of wireless headphones at once. That is different from QCU2 multipoint: earbuds multipoint connects the earbuds to two source devices and plays one stream at a time, while AirFly's two-headphone function can send one wired source to two headphone sets. This set page identifies one QCU2 pair; it does not include a second listener's headphones. These are two different connection arrangements, so do not treat the transmitter's two outputs as proof that the earbuds themselves play two streams or connect to two source devices.

Fit, noise control and codecs still depend on the earbuds

The Bose fit kit lists three eartip sizes and three stability-band sizes, with other sizes offered separately. A sealed tip needs to fit an individual's ear to support comfort and passive isolation; no fit test or cancellation measurement is claimed here. Bose's published ANC runtime is a maximum, not a promise for every volume, host, fit, battery age or feature setting. Bose lists SBC and AAC, and aptX Adaptive with a compatible Snapdragon Sound source. The exact AirFly-to-earbud codec negotiation is not stated in the reviewed set documentation, so the AirFly feature should not be treated as a guarantee that a particular advanced codec is active. For the simplest codec-specific comparison, pair the earbuds directly with a supported phone or computer; for a wired entertainment jack, verify the transmitter connection separately.

Package checks before buying

Match the set identifier, then check both selected component codes and finishes: Deep Plum QCUE2 earbuds and White AFPRO2 transmitter. Bose presents the component-level QCU2 box list (earbuds, fit kit, wireless case, cable and safety sheet) and separately lists AirFly Pro 2 contents (transmitter, charging cable, pouch, keychain attachment and documentation). The page does not present one consolidated outer-carton inventory, and a third-party listing or used package may differ. Confirm that it is Pro 2 rather than AirFly SE, that the correct 3.5 mm connector is present at your source, and that the standard kit includes no adapter you need. Bose says AirFly does not support telephony, so do not choose this set expecting calls through the transmitter. Also consider the same QCU2 earbuds without the transmitter if you only use Bluetooth sources.

The bundle has a clear use case: a shopper who wants sealed ANC earbuds and expects to listen from a standard headphone jack may value the included AirFly Pro 2 more than a separate case accessory. If that source is not part of your routine, the set adds another device to carry and charge without changing the earbuds themselves. Bose's U.S. set page, the QCU2 product page, and Twelve South's AirFly Pro 2 product details support this component-level reading; exact seller inventory and personal fit remain to be checked.
