These are Oppo’s Enco X4 earbuds, its flagship noise-cancelling product, which just made its international debut. The buds are launching alongside the Oppo Find X10 series.
In the box, you get the Enco X4 in its case along with S, M, and L silicone eartips.
Like previous Enco products, the X4 comes with Dynaudio-tuned sound, and the audio brand’s logo comes on the case itself. Oppo found a way to make the plastic case interesting by adding a subtle silver line accenting the top and bottom. The case is clad in a smooth, almost pearlescent plastic.
The Enco X4’s case
The case accepts both wired charging through USB-C and wireless top-ups. There’s also a discrete button for pairing, which you’ll likely never use as the buds support fast pair (you’ll get a notification to connect on your phone, tablet, or laptop).
A clean design – one button and one port
The Oppo Enco X4 themselves are in-ear buds and have stems, which aren’t too long. Inside the body of the bud sits a dual driver, comprising an 11mm woofer and 6mm tweeter. It’s a fourth-gen dual-driver design, and the drivers are paired with dual DACs.
Each stem has squeeze controls for play/pause, as well as engaging the different modes – active noise cancellation and transparency mode. ANC is advertised as 200% improved over the X3s, and you get a new 6nm NPU that works behind the scenes to adapt to different noise.
Each earbud has four microphones: three conventional silicon mics and one bone-conduction voice pick-up unit for calls, plus AI noise reduction. The buds are also IP55 rated. The Enco X4 offers conversation awareness, so it will stop music and ANC when it detects a conversation.
Finally, the Enco X4 comes with up to 53 hours of battery life. We recently had the chance to use the buds on a few flights and came away impressed. The earbuds are comfortable to wear, and the battery life feels robust – they showed half the charge left after a 5-hour flight.
Noise cancellation was also very effective during our tests on several flights, which is where these things count!
Very comfortable, nice controls
The Oppo Enco X4 has been available in China since September, but is coming to the UK, India, and Continental Europe. You can get the pair in either Aurora Violet or Glacier White. Currently, the price has a slight discount: in the UK it’s £189 (13% off), while in the EU it’s €199 (9% off) with an additional €20 voucher applied at checkout.
