Oppo Enco X3s

Name: Oppo Enco X3s
Brand: Oppo
SKU: 2001

Manufacturer: Oppo

The Oppo Enco X3s are true wireless in-ear earbuds designed for everyday listening, offering a compact build that weighs just 9.4 g per earbud. They carry an IP55 ingress protection rating, making them resistant to both dust and water splashing, which suits active or outdoor use. A travel bag is included in the box, and the earbuds support wireless charging through their charging case.

On the technical side, the Enco X3s use an 11 mm driver unit with a frequency range spanning 15 Hz to 40,000 Hz and a sound pressure level of 118 dB/mW. They support active noise cancellation alongside passive noise isolation, and include an ambient sound mode for situational awareness. Connectivity runs on Bluetooth 5.4 with LDHC and AAC codec support. The earbuds deliver up to 11 hours of playback on a single charge, or 6 hours with ANC active, with the charging case extending total battery life to 34 hours. Six microphones with noise-canceling capability handle calls and voice interaction, and fast charging is supported via USB Type-C.

Pros

IP55 rating provides protection against dust and water splashing, making them suitable for outdoor and fitness use
Active noise cancellation combined with passive noise reduction offers two layers of noise management
Wide frequency range of 15 Hz to 40,000 Hz paired with a 118 dB/mW sound pressure level indicates broad audio reproduction capability
The charging case extends total battery life to 34 hours, and wireless charging is supported
Six microphones with noise-canceling capability support cleaner voice transmission during calls
A travel bag is included, adding practical value for portability

Cons

Battery life drops noticeably from 11 hours to 6 hours when ANC is active
No in/on-ear detection means playback does not pause automatically when earbuds are removed
Lacks a find device feature, offering no way to locate misplaced earbuds through the system
No fast pairing or NFC pairing support, which may slow down the initial connection process
Maximum Bluetooth range is limited to 10 m
LDAC and the full aptX codec family are not supported, limiting high-resolution audio codec options

Who is this for?

The Oppo Enco X3s are well suited to users who want a capable daily-use wireless earbud with solid noise management. The combination of active noise cancellation and passive noise reduction makes them a practical choice for commuters, office environments, or anyone who regularly listens in noisy surroundings. The IP55 rating also makes them a reasonable option for light workouts or outdoor use where sweat and light rain are a concern, while the 34-hour total battery life with wireless case charging suits users who prefer longer periods between wired top-ups. The six noise-canceling microphones add value for those who frequently take calls or use voice input.

Who is this NOT for?

Users who prioritize high-resolution audio streaming may find the Enco X3s limiting, as neither LDAC nor any aptX variant is supported, leaving LDHC and AAC as the only codec options. Those who rely on automatic ear detection to pause playback when removing an earbud will find that feature absent here, which can be a daily inconvenience. The lack of a find device feature also makes these earbuds a poor fit for users who frequently misplace accessories, and the ANC battery life of only 6 hours means heavy ANC users may find endurance insufficient for longer days without recharging.

Final Verdict

The Oppo Enco X3s present a well-rounded set of specifications for everyday wireless earbud use, anchored by a dual-layer noise management system and a respectable total battery life backed by wireless case charging. The IP55-rated, fully wireless design combined with a six-microphone noise-canceling array positions these earbuds as a practical choice for commuters and active users who want reliable call quality and environmental noise control throughout the day. Codec support is limited to LDHC and AAC, and the absence of ear detection or a find device feature reflects trade-offs in the specification set that more demanding users will notice. Taken as a whole, the Enco X3s are a capable daily-use option for listeners who value noise management, durability, and battery endurance over audiophile codec flexibility.
