The noise cancellation data is based on real-life tests, and the ANC technology is sourced from OPPO Laboratory. The actual results will vary depending on the user's ear size, ear canal structure, ear tips used, wearing method, workout state, and other conditions. Touch controls are employed strategically to maximise functionality – adjusting volume, for instance, is achieved by sliding a finger up or down either earbud rather than using double or triple taps. Rounding out an impressive list of features are effective wear detection and active noise cancellation. The latter, in particular, is very good for the price and puts a significant dent in external sound. The 94 ms low latency was tested in OPPO Laboratory with the Enco X2 and OPPO Find X3 Pro, where "94 ms" is the time from when an on-screen button is tapped until the earbuds receive the sound.

The Samsung Galaxy Buds2 Truly Wireless have a great noise isolation performance, a comfortable in-ear fit, and some features only available on Samsung devices. However, they have a shorter continuous battery life than the Apple AirPods Pro (2nd generation) Truly Wireless and aren't as well-built.Switch down in file size to a 320kbps Spotify stream of Grouper’s Dragging a Dead Deer Up a Hill and there are the inevitable reductions in detail levels, while the soundstage loses a little of its unshakeable positivity too. But the Enco X remain eminently listenable, with plenty of observations to pass on about tone and timbre. A 10-minute charging for 8 hours play time, which is from the combination of earbuds and the case. Fast charging your OPPO Enco Air needs only a standard adapter or Type-C charging cable. Charging performance may vary. The Samsung Galaxy Buds+ Truly Wireless are the best wireless earbuds for sound quality that we've tested. These headphones are a great choice for listening to all sorts of genres thanks to their neutral and balanced sound, which is more versatile than the similarly-priced Google Pixel Buds Pro Truly Wireless. Whether you're listening to bass-heavy genres like EDM or vocal-centric content like folk music, these buds reproduce voices and lead instruments with great clarity and accuracy. If you want to switch up their sound, there are a couple of different EQ presets in their app, too. While they have a comfortable fit for most people, they can pop out of your ears over time. This can affect how the earbuds deliver bass, so getting a good fit is important to ensure consistent sound delivery. If you want earbuds with a more comfortable fit overall, the Sony LinkBuds S Truly Wireless are another great mid-range option. They have a more stable fit but a weaker ANC performance, though this may be better suited for runs where you want to stay aware of your surroundings. By ‘dangling stem’ standards the Oppo are reasonably discreet, mind you, and at 4.8g per earbud they’re hardly a burden to wear. Oppo provides many sizes of eartip in a selection of hardnesses, so getting the Enco X comfortable in your ear shouldn’t be difficult or time-consuming – and once they’re in place, they remain comfortable for hours on end.

On the inside, Oppo has wisely let Dynaudio have free rein – and let’s not imagine this isn’t a bit of a coup for Oppo. Dynaudio has a pretty much impeccable reputation in Hi-Fi circles, and it seems a bit weird that the Danish specialist hasn’t already delivered a pair of headphones or two under its own steam. Play time data is based on OPPO laboratory tests conducted at 50% speaker volume in music mode. Specific times for charging and use will vary according to actual circumstances. Using OPPO Enco Free headphones in Cinema mode or Game mode will reduce their play time. The midrange is detailed enough to extract all the nuance from Yorke’s vocal, while at the top of the frequency range there’s a great combination of substance and shine. Treble sounds will glint brightly when required, but even at considerable volume they never become hard or unruly. There were no surprises with the audio quality. Right off the bat, they are tuned in a way to make music pop with slightly raised bass and overall balanced output. This surprisingly remains the case even at higher volumes, exhibiting no signs of distortion. Most average users should like the sound profile, but audiophiles will be left wanting for more. While software side features are slim, hardware features are filled to the brim. The Oppo Enco Free implements Goodix’s Capacitive Touch Control chip to make the outer surface act as a navigation pad for all music controls. The stems can not only be tapped, but also swiped to interact with media.Other models will be supported after an OTA update (excludes A series, F series, Reno4 Z, Reno4 Pro, Reno2 Z, A significant proportion of buds now favour the use of silicone tips, which seal off your ear canals and secure the buds in your ears far better. They also have the advantage of providing improved passive noise cancellation. Manufacturers typically provide a range of different-sized tips to help ensure you get the most comfortable and stable fit possible. The Bluetooth® connectivity was tested in a strong interference environment. Both with LHDC on, the Enco X2's Bluetooth® connection is on average three times more stable than the Enco X's. Battery life: Earbuds will always have a stated battery life, as will the case used to charge them. Between 15 and 20 hours of total listening time is around average, though your mileage will vary depending on the volume at which you play your audio. Having advanced features such as ANC active will also drain your battery faster.

This 80ms latency refers to the latency data at the earphone side, and the overall latency experience depends on both device and earphones. This may vary between different devices. Though they can’t be described as class-leading in any one area, these uniquely versatile wireless earbuds more than justify their asking price.
