If you're looking for an inexpensive pair of true wireless earbuds for your daily commute, consider the Oppo Enco Air4 Pro. It has useful features, like wear detection and Bluetooth Multipoint. Noise cancellation is decent, and the sound is pretty good for the price.

For the Enco Air4 Pro, Oppo has gone with the stem design popularised by Apple's AirPods. You control these earbuds by tapping at the top of the stem for media playback, and doing a long press to switch between active noise cancellation (ANC) and transparency modes. If you have a compatible Oppo smartphone, you can also tap twice on the earbuds to take a photo with the phone camera. These controls generally work fine, though like other earbuds with similar controls, I found multiple taps to be finicky. There's also wear detection, a handy feature that pauses media playback when you remove any earbud, and resumes when you put them back in your ears.

Quick specs

  • 12.4mm dynamic driver
  • Up to 49-decibel active noise cancellation (ANC)
  • Wear detection
  • 12 hours of playtime per charge, 44 hours in total with charging case (ANC off)

As in-ear headphones go, the Oppo Enco Air4 Pro fits my ears comfortably. And no amount of headshaking dislodged them. If the default eartips aren't a good fit, you'll find two other sizes in the package. No charging cable is included for the case, which for my Midnight Black review set, comes in a dark matte colour with faint white specks. These earbuds also come in white. Oppo says the earbuds are IP55 water and dust resistant — you can use them in the rain — but the charging case isn't.

The Oppo Enco Air4 Pro has a personalised noise cancellation feature that tests your ear canals. I took several tries to complete this test — any slight movement messes it up. Honestly, I couldn't tell if it made any difference compared with the default ANC setting. While there's a Smart ANC option that adjusts the degree of noise cancellation to your surroundings, I usually went with the Max setting. This setting is effective at reducing the noise from car engines, though it's less adept at dampening noise from underground trains. Higher-frequency sounds like voices will also come through. Overall, the ANC is good — given the price of these earbuds.

The Transparency mode on the Oppo Enco Air4 Pro is decent. It doesn't sound overly artificial. Neither was there any weird hissing sound. Voices do come across a bit more muffled, perhaps due to the earbuds' passive noise isolation. Besides doing a long press on the earbuds, you can toggle between ANC and Transparency using Oppo's HeyMelody app. This app also enables other useful features, from updating the firmware to enabling the dual connection feature that lets the Oppo Enco Air4 Pro connect to two source devices simultaneously via Bluetooth. However, I was disappointed that the equaliser in the app isn't customisable. You either choose to boost the bass or opt for clearer vocals, but you cannot adjust the levels.

For its price (S$129), the Oppo Enco Air4 Pro sounds good. There's a good amount of bass that gives the sound a certain heft and depth. Trebles are clear, while the audio separation is good with a wide soundstage. I would say these earbuds are balanced, and sound fine to most folks. They also support the LHDC 5.0 codec that offers high-resolution audio streaming over Bluetooth. But you'll need a compatible device, mostly likely a smartphone from Chinese brands like Oppo and Xiaomi.

Oppo says the Enco Air4 Pro earbuds can last around 12 hours on a single charge without ANC. This goes up to 44 hours with the charging case. In my testing (50% volume, ANC enabled), these earbuds dipped by around 10% battery life after an hour of use. That's quite good. Oppo says you can get around 4 hours of use (no ANC) by just placing the earbuds into the charging case for 10 minutes. Meanwhile, if you're topping up the charging case, 10 minutes of charging (via USB-C) will get around 11 hours of use (no ANC).

The Oppo Enco Air4 Pro (S$129) is more expensive than the Redmi Buds 5 Pro (S$99), though if you aren't too concerned about local warranty, you can import the China version for around S$80. Both the Oppo and Redmi earbuds have similar features like wear detection and dual device connectivity. But the Oppo sounds slightly better to me than the Redmi, and can go just a bit longer without charging. Get the Enco Air4 Pro from Shopee and Lazada.
