Nothing Ear (a) vs OnePlus Buds Pro 3 Comparison

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.

OnePlus Buds Pro 3

Three microphones per bud handle calls, with AI noise reduction to separate your voice from background noise. For laptop meetings they work as standard Bluetooth headsets. A business earbud with a dongle remains better for daily Teams use. Colleagues on Teams or Zoom will hear you clearly from a quiet room, but in a busy cafe the voice processing can clip the ends of words.

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.

OnePlus Buds Pro 3

OnePlus rates adaptive ANC at up to 50 dB, with a transparency mode for hearing your surroundings. Cancellation is strong on public transport and in offices, competing with more expensive flagships against low-frequency noise. Voices and sudden sounds get through a little more than with Bose. Adaptive mode adjusts strength to your environment, which helps battery life in quieter spaces.

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.

OnePlus Buds Pro 3

OnePlus quotes up to 43 hours total with the case using AAC and ANC off, or 25.5 hours with ANC on. That covers several days of commuting before charging the case. LHDC with ANC drops total time to about 21.5 hours. The case supports USB-C and wireless charging, and fast charging gives hours of playback from a short top-up.

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.

OnePlus Buds Pro 3

The stem design is larger than some rivals, but the buds sit securely. OnePlus includes several tip sizes, and the buds are water resistant for sweat and rain. The stems are easy to grip for removing and adjusting, and touch controls on the stem respond reliably. Smaller ears may find the stems press against the tragus after a couple of hours, so try each tip size before deciding.

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.

OnePlus Buds Pro 3

Bluetooth 5.4 supports dual connection to two devices at once and Google Fast Pair on Android. Dual connection keeps the buds linked to a phone and laptop, so calls switch automatically. The HeyMelody app adds EQ and settings on non-OnePlus phones. On OnePlus phones, controls are built into the system settings, which makes setup faster than on other devices.

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.

OnePlus Buds Pro 3

Each bud combines an 11 mm woofer and a 6 mm tweeter. LHDC 5.0 supports up to 24-bit / 192 kHz at 1 Mbps on compatible phones, with AAC and SBC for others. The two-way design gives deep, controlled bass and clear treble, with Dynaudio tuning that avoids harshness. Detail is strong for the price, and the EQ in the app lets you fine-tune the balance.
