OPPO Enco X4 Earbuds Launched in India at Rs 19,999

OPPO has launched the Enco X4 true wireless earbuds in India at Rs 19,999. Pre-orders are open, and sales start on 29 October, the same day as the Find X10 series. Here is everything you need to know about them.

Update, 29 October: sales of the OPPO Enco X4 have started in India today. They are on OPPO's online store, Amazon, Flipkart and partner stores. Prices and offers can change, so check the final price on the store page before you pay.

Enco X4 price, colours and sale

The Enco X4 costs Rs 19,999 in India and comes in two colours, Aurora Violet and Glacier White. It goes on sale on 29 October on OPPO's online store and Amazon. Before the launch, OPPO India ran a Rs 9 privilege pack that gave a Rs 500 coupon for the Enco X4, valid from 22 to 25 October. We have not seen other launch offers.

Sound quality

Each earbud has dual dynamic drivers, an 11mm woofer and a 6mm tweeter, with two separate DAC chips. The sound is tuned with Dynaudio, a Danish speaker maker. OPPO says the bass is stronger and the distortion lower than on the Enco X3, based on its own lab tests.

The earbuds support the LHDC, AAC and SBC codecs. With LHDC they can stream at up to 2.3Mbps, which OPPO calls lossless, but this needs a compatible OPPO Find X series phone. Phones from other brands will fall back to a normal codec. In the app, you get a 10-band equaliser with five presets, including two Dynaudio profiles, Pure Vocals, Crisp Highs and Thundering Bass. A feature called Golden Sound scans your ear canal and builds a sound profile for you.

Noise cancellation

The Enco X4 has adaptive noise cancellation that reads your surroundings in real time and changes how strongly it works. There are three levels you can pick by hand. OPPO claims its noise cancellation is twice as effective as the previous generation overall, and 30% better against human voices. The earbuds also have a Conversation Awareness mode, which lowers the volume and switches to transparency when you start talking.

Calls and AI features

Calls use three microphones per earbud and a bone-conduction sensor that picks up your voice, with AI noise removal on top. The earbuds also have AI Live Translation: the translated speech plays in your ears while the text shows on your phone. It works with select OPPO and OnePlus phones running ColorOS 17. Other extras include Spotify Tap, "Hey Google" voice access to Gemini and neck posture alerts.

Battery life

These are the numbers OPPO gives for India:

A 10-minute charge gives up to 14 hours of listening, and a full charge of the earbuds takes about 65 minutes. Each earbud has a 65mAh battery, and the case has a 576mAh battery with a USB-C port.

Connectivity and build

The earbuds use Bluetooth 6.1 and can stay connected to two devices at once, across Android, iOS and Windows. The earbuds are rated IP55 for dust and water. The case is not. They come with silicone tips in four sizes.

Is it worth Rs 19,999?

This is a premium price, and the best parts of the package, the lossless streaming and the live translation, work fully only with OPPO or OnePlus phones. If you own a Find X10 or another recent OPPO phone, the Enco X4 is a good match. If you use a phone from another brand, check that the sound and noise cancellation are worth the money before you buy.
