OPPO Enco X4 Overview
Design and Comfort
The OPPO Enco X4 Earbuds go for a clean look that blends matte and glossy finishes. The charging case adds metallic edges for a more premium feel. Buyers can pick between Glacier White and Aurora Violet.
Comfort gets plenty of attention here. The foam silicone ear tips come from data gathered through more than 2,800 ear canal scans which helps with a secure fit during long listening sessions. Each bud weighs around 5.6g. The buds carry IP55 dust and water resistance for everyday use while the charging case has no such rating.
Audio Quality and Dynaudio-Tuned Dual-Driver System
Sound is the main selling point of these dual-driver earbuds. Each OPPO Enco X4 Earbuds bud packs an 11mm TRF woofer for bass and a 6mm planar tweeter for highs. Both drivers run on their own DAC so every frequency range gets handled separately.
The Dynaudio co-tuned acoustic system adds five sound profiles that include Original Sound, High-Resolution, Pure Vocals, Crisp Highs and Thundering Bass. Listeners can switch between them based on genre or mood. The earbuds cover 10Hz to 40kHz and hold Hi-Res Audio Wireless certification.
2.3Mbps Lossless Audio and Spatial Audio Support
Lossless playback is the headline feature. These are the first earbuds from the brand to support the LHDC Lossless audio codec with up to 24-bit/48kHz audio at 2.3Mbps. That bitrate helps preserve more detail from the original recording.
There is a catch though. Full lossless audio stays off by default and works only with a Find X10 series phone. Other phones fall back to AAC, SBC, LHDC or LC3. Cross-ecosystem spatial audio with head tracking is easier to use since it works on Android, iOS and Windows devices.
AI Adaptive ANC and Noise Cancellation
Noise cancellation gets a big upgrade this time. A triple-microphone system works with a 6nm NPU to power the ANC on the OPPO Enco X4 Earbuds. OPPO claims 100 percent stronger overall performance than the Enco X3s plus 30 percent better results across speech frequencies.
AI Real-time Adaptive ANC recognises places such as metro trains, buses, taxis and airplanes then adjusts the cancellation to match. Conversation Awareness lowers the music and switches to transparency mode as soon as the wearer starts talking.
AI Clear Call and Call Quality
AI Clear Call is built for noisy places. Three microphones work with a bone-conduction voice pickup unit to catch the wearer’s voice more accurately. This helps keep calls clear on busy streets and crowded commutes.
Content creators also get something useful. Dolby-powered Clear Audio Recording captures stereo sound with a natural sense of space which adds depth to video content.

Smart Features and AI Live Translation
Bluetooth 6.1 brings faster and more stable connections. Dual-device connectivity lets the earbuds stay paired with two devices at once across Android, iOS and Windows. Compatible OPPO phones also get Smart Bluetooth with a claimed range of up to 400 metres in open areas.
Google Gemini support allows “Hey Google” voice activation on compatible devices. A 10-band Sound Master EQ and neck posture reminders add more control for daily use.
AI Live Translation covers more than 30 languages. The full experience works only on select OPPO and OnePlus phones running ColorOS 17 or later.
Battery Life and Charging
Battery life is one of the stronger points of the OPPO Enco X4 Earbuds. The buds are rated for up to 13 hours of music on a single charge. The charging case stretches that to 53 hours in total. These numbers come from AAC playback with ANC turned off and the volume set to 50 percent.
Real-world use with noise cancellation switched on will be lower. With ANC enabled the earbuds are rated for about 6 hours on a single charge and 26 hours with the case. Quick top-ups are handled over USB Type-C. A 10-minute charge is claimed to deliver up to 14 hours of music playback, which helps when the buds run low before a commute.

OPPO Enco X4 Price and Availability in Nepal
In India, the OPPO Enco X4 Earbuds are priced at INR 19,999. Sales start on October 29 through OPPO’s official website and Amazon India. The earbuds come in Glacier White and Aurora Violet.
| TWS | India (Official) | Nepal (Converted) |
|---|---|---|
| OPPO Enco X4 | INR 19,999 | NPR 31,999 |
There is no official announcement about an OPPO Enco X4 launch in Nepal yet. Based on a standard currency conversion, the pair can be expected to arrive at around NPR 31,999 if it launches locally. This is only an estimate, so the final price may differ.
Should You Buy the OPPO Enco X4 Earbuds?
The OPPO Enco X4 Earbuds are a well-rounded premium pair with Dynaudio-tuned sound, capable adaptive ANC and battery life that lasts well beyond a full day. The main drawback is that 2.3Mbps lossless audio works only with a Find X10 series phone. Other buyers still get strong sound, dual-device connectivity and useful smart features, which makes it a solid pick for Nepali buyers if it launches locally.
