Price

The Acefast AceFit Air were announced in January 2025 and are available through Amazon where they’re priced at £79.99.

That makes them cheaper than other big-name open-eared-style earbuds like the ShokzOpen Fit Air (£119), which is under £100 from some retailers.

They’re less expensive than the Nothing Ear Open (£99), Huawei FreeArc (£99) and solid performers like the Oneodio OpenRock X (£149.99) and EarFun OpenJump (£129.99).

Design

• Available in black or white
• Weight 7.5g per earbud
• IP54 water resistant rating

The design of the Acefit Air isn’t too dissimilar from other open-ear earbuds I’ve had in and around my ears – particularly the ones made by Shokz. You can pick them up in either black or white and they are supremely light to wear, which makes them easy to forget about when they’re on.

Crucially, the earhook design is well-balanced and even during more energetic use have stayed pretty securely in place. They’re comfortable too, with the soft silicone exterior and titanium in the ear hooks offering some flex in the design.

They’ve got a pretty low profile for an ear hook-style earbud which extends to the charging case; which is thin, light and easily disappears in your pocket.

There is room for dual microphones for calls plus a set of onboard controls of the touch variety baked into the surface of the buds. You can tap single or multiple times as well as long press to perform functions like adjusting volume, skip songs, answer a call or summon your smartphone assistant or turn the earbuds on.

It’s good that you’re able to adjust how the gesture controls are assigned, though I found the using the touch controls more manageable and responsive to taps when stationary than when on the move or during exercise.

To guard against dust and sweat and rain they carry an IP54 water resistant rating, which doesn’t extend to the charging case, but does give it the same level of protection against moisture as earbuds like the Shokz OpenFit Air.

Battery life

• Up to 5-6 hours battery life
• Fast charging support

The battery life delivered can be anywhere from 5-6 hours based on listening at 60% volume and whether you’re using them for streaming audio or taking calls. I typically felt I needed to listen to louder than 60%, especially when outside, to get the best sound experience. That meant listening for an hour would typically see the battery drop between 15-20%.

While it’s also useful to have the battery status for each earbud displayed inside of the companion app, there’s no battery percentage provided to give you a clear sense of how much power you have left to play with.

There is at least a quick charge mode that gives you two hours of listening time from a 10-minute charge, which does make up for that not so glowing battery performance.

Sound Quality

• Uses air conduction
• EQ presets and custom EQ available

Like all open-ear earbuds and headphones, there’s big talk about what you can expect from the Acefit Air. They use air conduction as opposed to bone conduction, so place 3-magnet ultra linear speakers close to your ears to deliver sound. From the Acefast phone app you can access a set of EQ modes to adjust that sound profile.

Acefast suggests you can expect excellent high, low and mid frequencies, great power and high fidelity sound and as far as delivering on those fronts, It falls a bit short on most fronts though.

Let me start with the positives: they can go pretty loud and in general deliver reasonably warm sound.

Get into the nitty gritty and these aren’t the clearest, most balanced open-ear earbuds, especially when compared to the competition. Drifting from the Original Sound EQ, Bass and Human Voice EQ presets, as well as toying with the custom EQ options, and I’ve found that across the board, these aren’t the most polished sounding open-ear earbuds I’ve tested.

On Fleetwood Mac’s Rhiannon, bass is muddy and unclear, mids are recessed and trebles hardly sparkle. It’s a similar story on Van Morrison’s Moondance where there are more signs of that slightly muddy feeling and there’s graininess to the treble that can be a good thing in some instances, but in this case not so much.

Throwing a more bass heavy track into play like A Tribe Called Quest’s Can I Kick It and even with Bass mode in play there’s a woolly feeling that dominates and prevents getting a  likable tune in the mid and treble departments.

If you’re turning to them for podcasts, audiobooks and calls, they perform better. The shift to a focus on voices makes the best use of the Air’s audio architecture. The problem the Air faces is that in a bid to cover all bases, it sits somewhere in the middle of everything and doesn’t do anything really well.

There’s some other good too, like not leaking your sound terribly at louder volumes and the ease of connecting them to two devices and being able to switch between the two.

Should you buy it?
