Bose QC Ultra Earbuds vs Poly Voyager Free 20 Comparison

Bose QC Ultra Earbuds

The second generation brought upgraded microphones and processing for calls, one of the main complaints about the first model. The mics focus on your voice and reduce surrounding noise and wind before the signal reaches the phone. Unlike many business earbuds, they ship without a USB adapter for laptop calls.

Poly Voyager Free 20

Each bud has three noise-cancelling microphones, which Poly aims at your mouth to separate your voice from typing and background chatter. Poly processing suppresses typing and background chatter well. Without a dongle, laptop calls use standard Bluetooth, which narrows the audio when the mic is active. The Voyager Free 60+ includes a USB adapter for steadier PC calls and certification.

Bose's ActiveSense ANC is among the strongest in any earbud. It removes engine drone and air-conditioning hum, and does better than most rivals with voices and office chatter. Aware mode lets sound in naturally, and ActiveSense reduces sudden loud noises while staying in Aware. That is useful on city streets.

Poly Voyager Free 20

Adaptive ANC adjusts its strength to the surroundings, and a transparency mode lets you hear colleagues without removing a bud. Poly keeps the controls simple, with a long press switching between the two modes. Cancellation is good in offices and on commutes, reducing air conditioning hum and distant chatter. It is not as strong as premium consumer buds such as the AirPods Pro 3, but enough to help with focus work.

Bose quotes about 6 hours of listening per charge, or about 4 hours with Immersive Audio, and the case adds roughly three more charges. That is enough for most flights and workdays, though Sony and Poly last longer per charge. Immersive Audio is the main battery drain, so switch it off on long trips and save it for films.

Poly Voyager Free 20

Poly quotes up to 8 hours with ANC on and 12 hours off, with 28 and 42 hours total with the case. That is enough for a full workday of calls and music without a top-up. Few business earbuds last as long. The case charges by USB-C or on a Qi wireless pad, so a desk charger keeps it topped up without cables.

The buds are larger than most, and they use ear tips plus stability bands in three sizes to hold them in place. The water rating is IPX4, which covers sweat on a run and rain on the way to the station, but not a drop into water.

Poly Voyager Free 20

The buds are light and shaped for long wear, with several tip sizes and an IP56 rating for dust and water. Many users can wear them through a full workday without discomfort. The shape stays stable when you talk, which matters on long calls. The case is compact and charges wirelessly on a Qi pad, which suits desk setups that already have a wireless charger.

Bluetooth 5.3 brings two-device multipoint and Google Fast Pair, and aptX Adaptive kicks in on compatible Snapdragon phones. Switching from a laptop call to a phone call happens without re-pairing. Bose says the second generation has a more stable connection, especially in crowded places such as stations and airports. Bose offers no USB adapter and no meeting-platform certification for these buds.

Poly Voyager Free 20

Bluetooth 5.4 supports multipoint, keeping the buds connected to a phone and a laptop at the same time so you do not need to re-pair between devices. Switching between devices is automatic when a call arrives. Poly Lens app on mobile and desktop handles settings and updates. They are not certified for Teams or Zoom, and no USB dongle is included.

CustomTune plays a chime when you put the buds in, measures your ear canal and adjusts EQ and ANC to match. Bose's Immersive Audio adds a spatial mode with Still and Motion settings. The tuning is warm and full, with strong bass and smooth highs. On Snapdragon Sound phones aptX Adaptive improves quality, while iPhones use AAC.

Poly Voyager Free 20

Each bud has a 10 mm speaker, and Poly tunes them for clear voice reproduction. Codec support covers SBC and AAC. For background music while working they are pleasant, but music lovers will prefer consumer-focused buds with richer tuning. The Poly Lens app offers EQ presets that add a little warmth for listening between meetings.
