Bose QC Ultra Earbuds vs Nothing Ear (a) 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.

Nothing Ear (a)

Each bud carries three microphones, and Nothing's Clear Voice processing is trained to separate speech from background noise such as traffic and chatter. Voice quality is clear indoors and acceptable outside. Wind can still cause some interference, which is common at this price. For laptop calls, the buds act as standard Bluetooth headsets.

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.

Nothing Ear (a)

Nothing rates the ANC at up to 45 dB, with adaptive and transparency modes. Smart ANC adjusts strength to your environment. Cancellation is excellent for the price, quieting trains and office hum effectively. It cannot match flagships with voices, but it beats most budget rivals. A good tip seal improves results noticeably, and the app's ear tip fit test helps you choose the right size.

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.

Nothing Ear (a)

Nothing quotes up to 9.5 hours per charge and 42.5 hours with the case with ANC off, or 5.5 and 24.5 hours with ANC on. With ANC on, a full workday needs a recharge in the case. Without ANC, battery life is excellent. The case charges over USB-C, and there is no wireless charging.

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.

Nothing Ear (a)

Each bud weighs 4.8 g, and they are rated IP54 for dust and splashes. The stem design is light and secure. The transparent stems look distinctive and fit easily in most ears. The case weighs 39.6 g and is wide, which makes it less pocketable than some rivals. The transparent lid shows the buds inside.

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.

Nothing Ear (a)

Bluetooth 5.3 supports multipoint, Google Fast Pair and Microsoft Swift Pair. The Nothing X app works on Android and iOS. Multipoint keeps the buds connected to a phone and laptop, which suits hybrid workers. On Nothing phones, ChatGPT voice integration is available. The app handles EQ, gesture mapping, ANC modes and firmware, with a low-lag mode for games and video.

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.

Nothing Ear (a)

Each bud uses an 11 mm dynamic driver with a PMI and TPU diaphragm. Codecs include SBC, AAC and LDAC for higher-resolution streaming on compatible Android phones. The sound is balanced with lively bass and clear vocals. LDAC adds a touch more detail, while the Nothing X app's EQ lets you adjust tuning for podcasts or music.
