Oppo Enco X3i

Name: Oppo Enco X3i
Brand: Oppo
SKU: 98621

Manufacturer: Oppo

The Oppo Enco X3i are fully wireless in-ear earbuds designed for everyday listening without the hassle of cables. They carry an IP55 ingress protection rating, meaning they hold up against dust and water splashing from any direction — a practical consideration for workouts or commutes. A travel bag is included in the box, and the earbuds support in-ear detection, which automatically pauses playback when removed.

On the technical side, each earbud uses a 10.4 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz, and the active noise cancellation is backed by six microphones with noise-canceling capability for both calls and audio. Bluetooth 5.3 handles the wireless connection, with LDHC codec support and a maximum range of 10 m. Battery life reaches 7 hours per charge — or 6.5 hours with ANC active — and the charging case extends total playback to 37 hours. Fast charging is supported via USB Type-C, and the earbuds can connect to two devices simultaneously through multipoint pairing.

Pros

The combined 37-hour total battery life from the earbuds and charging case supports extended use across multiple days without frequent recharging
Six microphones with noise-canceling capability make for clearer call quality in environments with background noise
IP55-rated dust and water resistance adds durability for outdoor and workout use
Simultaneous connection to two devices via multipoint pairing reduces the need to manually switch between sources
Ambient sound mode and in-ear detection together offer flexible listening awareness and automatic playback control
A travel bag is included in the box, making transport and storage more convenient from the outset

Cons

Wireless charging is not supported, so the case must always be charged via cable
No aptX variants or LDAC are available, limiting high-resolution audio codec options to LDHC and AAC
Audio latency of 94 ms may be noticeable during video playback or gaming for sensitive users
The maximum Bluetooth range of 10 m is relatively short, restricting movement from the connected source device

Who is this for?

These earbuds are a solid match for commuters and office users who want reliable active noise cancellation alongside the convenience of multipoint pairing to switch between a phone and laptop without manual reconnection. The IP55 water and dust resistance, combined with a 37-hour total battery life, also makes them practical for people who work out regularly or spend long hours away from a charger. In-ear detection, ambient sound mode, and a six-microphone noise-canceling setup further support those who take frequent calls or need situational awareness throughout the day.

Who is this NOT for?

Users who prioritize the highest-resolution wireless audio will find this model limiting, as it lacks LDAC and all aptX variants, restricting codec options to LDHC and AAC. Those who frequently watch video or play games with latency-sensitive content may also find the 94 ms audio latency noticeable. Additionally, users who prefer the freedom to move far from their source device may find the 10 m Bluetooth range restrictive in larger spaces.
