Bose QC Ultra Earbuds vs Samsung Buds4 Pro 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.

Samsung Buds4 Pro

Each bud has two high-SNR digital mics, a third digital mic and a voice pickup unit. Super Clear Call uses super wideband and machine learning for noise reduction on Galaxy devices. Super wideband doubles the bandwidth of conventional Bluetooth calls, so your voice sounds fuller on supported phones. The noise reduction is built for busy places such as restaurants and playgrounds.

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.

Samsung Buds4 Pro

Buds4 Pro use enhanced Adaptive ANC that analyses ear shape and fit, plus Ambient sound, Voice Detect and Siren Detect. The two-way speaker is positioned to reduce wind feedback. On buses and trains the ANC removes much of the engine rumble, which makes calls and podcasts easier to follow. Voice Detect boosts ambient sound when you start talking and restores ANC afterwards.

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.

Samsung Buds4 Pro

Samsung rates the buds at up to 6 hours with ANC on or 7 hours with it off. The case extends that to 26 or 30 hours. Talk time is up to 4.5 hours with ANC on. That covers a commute and several meetings, though a long day of calls will need a break in the case.

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.

Samsung Buds4 Pro

Each bud weighs 5.1 g with the medium tip and measures 18.1 x 19.6 x 30.9 mm. The buds are rated IP57, but the case is not water resistant. Samsung says it refined the fit through more than 10,000 simulations, producing smaller earbud heads that sit securely. The canal fit seals well, which helps both bass and noise cancelling.

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.

Samsung Buds4 Pro

Buds4 Pro use Bluetooth 6.1 with Samsung Seamless Codec, AAC, SBC and LC3, plus Auracast broadcast audio. Auto Switch moves between Galaxy devices. Opening the case pairs them instantly with Galaxy phones and tablets, and settings sit in the quick panel. On other Android phones the Galaxy Wearable app is needed for advanced controls.

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.

Samsung Buds4 Pro

Each bud pairs an 11 mm woofer with a 5.5 x 3.5 mm tweeter. Samsung says the wider woofer increases effective speaker area by almost 20% over the previous generation, and UHQ mode supports 24-bit / 96 kHz on compatible Galaxy devices. The result is a fuller, more spacious sound, with clean bass and clear treble.
