Soundpeats Opera03

Manufacturer: Soundpeats

The Soundpeats Opera03 are true wireless in-ear earbuds with an IPX4 sweat-resistant rating, making them suitable for workouts and everyday wear. Each earbud weighs just 10 g, and the pair comes with a travel bag included. Active noise cancellation is built in alongside an ambient sound mode, giving users control over how much of their surroundings they hear. A noise-canceling microphone is also on board, allowing the earbuds to double as a headset for calls.

On the connectivity side, the Opera03 use Bluetooth 5.3 with a maximum range of 10 m and support both AAC and LDAC for higher-quality wireless audio transmission. The earbuds carry a 40 mAh battery rated for 9 hours of playback, while the 300 mAh charging case extends total listening time to 24 hours; a full charge via USB-C takes around 1.5 hours, and fast charging is supported. A battery level indicator is included, though wireless charging is not available. The earbuds feature a 12 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, passive noise isolation, stereo output, voice prompts, a mute function, and on-device controls. Fast pairing, NFC pairing, and in/on-ear detection are not included. The warranty period is 1 year.

Pros
  • LDAC support enables higher-quality wireless audio transmission compared to standard Bluetooth codecs
  • Both active noise cancellation and passive noise isolation work together to reduce environmental sound from two separate mechanisms
  • The 24-hour total battery life including the charging case provides solid all-day usage without needing access to a power outlet
  • Fast charging is supported, reducing downtime when the earbuds do need to be topped up
  • A noise-canceling microphone is included, making the earbuds more capable for calls in noisy environments
  • A travel bag is included in the box, adding practical value for users who carry their earbuds on the go
Cons
  • No in/on-ear detection means music will not automatically pause when an earbud is removed
  • Wireless charging is not supported, requiring a cable to recharge the case each time
  • Fast pairing is absent, so connecting to a new device requires manual Bluetooth pairing each time
  • No find device feature is available, making it harder to locate misplaced earbuds
  • Wingtips are not included, which may reduce stability during physical activity for users who need extra ear fit security
  • The maximum Bluetooth range is limited to 10 m, which restricts movement away from the source device
Who is this for?

The Soundpeats Opera03 are a solid fit for users who prioritize audio quality in their wireless earbuds, particularly those with devices that support LDAC for higher-resolution Bluetooth streaming. The combination of active noise cancellation and passive noise isolation makes them well-suited for commuters, office workers, or anyone regularly dealing with background noise who wants consistent sound blocking. The IPX4 sweat-resistant rating and lightweight 10 g build also make them practical for gym use and light outdoor activity, and the 24-hour total battery life with fast charging support means they can handle full-day use without much planning around recharging. Users who frequently take calls will also benefit from the noise-canceling microphone and mute function for clearer, more controlled conversations.

Who is this NOT for?

Users who rely on automatic ear detection to pause music when an earbud is removed will find that feature missing, which can be a daily inconvenience. Those who regularly move far from their audio source may find the 10 m Bluetooth range limiting, particularly in larger spaces or open environments. Runners or athletes who need a secure fit during intense movement may be disappointed by the absence of wingtips, as there is no bundled option to improve stability in the ear. Users who prefer the convenience of wireless charging for their case will also need to adjust, as only wired USB-C charging is available.

Final Verdict

The Soundpeats Opera03 make a coherent case for users who want capable true wireless earbuds with a meaningful focus on audio quality and noise management. LDAC support alongside dual-layer noise control — both active and passive — gives the earbuds a clear functional identity that suits commuters, office listeners, and fitness users alike. The 24-hour combined battery life, fast charging, noise-canceling microphone, and IPX4 rating round out a feature set that covers most day-to-day scenarios well. Some conveniences are missing — notably wireless case charging, ear detection, and fast pairing — but these are trade-offs rather than fundamental shortcomings. For listeners who put audio transmission quality and noise blocking at the top of their list, the Opera03 deliver a focused and well-equipped experience within the true wireless category.
