Budget multi-driver earbuds prove that fit and software now define value, not just drivers

Recent independent reviews reveal that affordable multi-driver earbuds are competing not only on hardware but also on fit, software quality, and practical features, reshaping the perception of value in the budget segment.

The most revealing finding from the latest wave of budget multi-driver earbuds is not that brands have managed to squeeze two drivers into ever cheaper TWS designs. It is that once independent testing replaces the marketing sheet, the category breaks into three very different propositions. Among the models backed by detailed third-party reviews, CMF by Nothing’s Buds Pro 2 looks the strongest all-round budget option, Huawei’s FreeBuds 6 stands out for buyers who dislike sealed in-ear tips, and Anker’s Soundcore Liberty 4 Pro offers the broadest feature list but with a less clear-cut value case. That is a more useful conclusion than simply counting drivers or quoting headline frequency ranges. (soundguys.com)

What separates these earbuds is not the existence of a second transducer, but how the surrounding system behaves in day-to-day use. Reviews of all three show the same pattern: codec support is sometimes hidden behind an app, quoted battery figures do not always survive lab testing, and fit can matter more than audio hardware. SoundGuys found that CMF’s LDAC mode must be enabled in the Nothing X app, while Android Authority reported that Huawei’s AI Life software is awkward on non-Huawei Android phones because it is not on the Play Store and must be sideloaded. In other words, the practical barriers now sit outside the driver housing itself. (soundguys.com)

CMF’s case is the clearest example of a budget model that mostly delivers on its promise. The earbuds use an 11mm primary driver with a 6mm secondary unit, support AAC and SBC as standard, and add LDAC for compatible phones through the companion app. SoundGuys said the Bluetooth 5.3 connection was stable to 10 metres and measured about 6 hours and 15 minutes of playback with ANC enabled, well below the headline figure but still respectable for the class. More importantly, it found the ANC unusually strong for the money, cutting perceived outside noise by roughly 81% overall. RTINGS reached a similar conclusion from a different angle, saying the CMF pair is bassier than the Nothing Ear (a), with slightly longer battery life and more effective ANC, though the more expensive Nothing set has stabler fit and more predictable controls.

Anker goes further upmarket, and the reception is correspondingly more mixed. The Liberty 4 Pro combines LDAC, Bluetooth multipoint and a charging case with a small display and a touch bar on the front. SoundGuys found that arrangement useful for quick battery checks and mode changes, but summed it up bluntly: “The case is unique, but not practical”. Tom’s Guide was harsher, describing the product as an attempt to move Soundcore into the mid-range with “mixed results”, adding that the case interface was clunky and the earbuds felt expensive against rivals such as Sony’s WF-C700N and the OnePlus Buds 3. The split extends to endurance: Tom’s Guide lists rated battery life at 7.5 hours with ANC on, whereas SoundGuys measured 5 hours and 42 minutes. What both reviews do agree on is that ANC is strong for the price, with SoundGuys measuring around 30dB of low-frequency reduction, and that the app offers enough EQ control to tame the default bass lift if needed.

Huawei’s FreeBuds 6 takes the most unusual route because it tries to pair a dual-driver system with an open-fit shell. That immediately trades away passive isolation, but it also creates the product’s main appeal. PhoneArena’s June 2025 review called the proposition “hype vs reality” and warned that “satisfaction may vary”, despite noting the 11mm dynamic driver, planar diaphragm tweeter, 14Hz-to-48kHz claimed range, tap-and-swipe controls, Bluetooth multipoint and IP54 protection. It also criticised battery life, putting the buds at 4 hours with noise reduction on and 5.5 hours with it off. Android Authority’s later July review was noticeably warmer, arguing that Huawei’s included rubber covers made the fit significantly more secure and comfortable and that the sound came surprisingly close to Apple’s AirPods Pro 2, even if it did not match them. Taken together, those verdicts point to a niche but credible product: stronger than the bare specification suggests, yet still limited by the compromises of open-fit design and Huawei’s awkward software setup outside its own ecosystem.

For buyers comparing affordable multi-driver earbuds, the lesson is straightforward. CMF looks like the safest recommendation if noise cancellation and value matter most. Anker offers more toys, more customisation and better call and travel features, but its pricing pushes it into a tougher fight and its clever case does not convince every reviewer. Huawei is the outlier for listeners who want a lighter, less intrusive fit and are willing to accept weaker isolation, shorter battery life and software friction. The hardware race has plainly moved on from the old assumption that cheap TWS means one driver and muddied sound. But the independent reviews also show that two drivers alone no longer tell you enough. Fit, app quality, codec access and measured ANC now decide whether a budget pair is genuinely good or merely well advertised. (soundguys.com)
