Acefit Pro by Acefast: These headphones will be a real eye-opener

If you want to listen to music or podcasts but still enjoy feeling a gentle breeze in your ear canal, bone conduction headphones are the way to go. Or open-ear headphones. The Acefit Pro are appealingly priced. But do they deliver on performance too?
They tend to rank lower down the sales charts at Digitec and Galaxus: Open-ear headphones. Customers tend to prefer in-ear and over-ear headphones.
My colleague Siri recently tried out a pair of air-conduction open-ear headphones from Bose. I recommend her review if you’re prepared to spend 200 francs or more. I’ve found some open-ear headphones a price bracket or two lower that performed surprisingly well when tested: the Acefit Pro from Acefast.
Of course, the sound quality of open-ear headphones doesn’t come close to that of in-ear models, such as the AirPods Pro. Unlike the Apple earbuds, I don’t insert the Acefit Pro into my ear canal; instead, I hook them over my ear. The sound is directed towards the ear canal through small openings. The advantage: I can still hear what’s going on around me. I’ve been wearing open-ear models and those that use bone conduction for several years now when I go jogging.
If you’re one of those audiophiles who wants to be able to pick out the violin in the third row of the orchestra, steer clear of the Acefit Pro – and open-ear models in general, for that matter. The subtle nuances of the music are easily lost on their way to your eardrum.
Sound: Music and podcasts sound good
During testing, however, I was pleasantly surprised by the quality. Whether it’s ‘ «’, ‘Don’t Marry Her’» (The Beautiful South), ‘ «’, ‘Summer of ‘69’» (Bryan Adams) or ‘ «’, ‘Ordinary’» (Alex Warren) – whilst running, I can hear the background instruments in all the songs and am satisfied with both the highs and the lows. Acefast refers to the «3-magnet super-linear speaker», which is said to deliver powerful bass and clear treble. Yes, that’s certainly true for me.
When I listen to a podcast, I briefly open the Acefast app beforehand. There I find four preset equaliser settings: Original Sound, Live, Subwoofer and Vocal. The latter option provides a noticeably better experience when listening to podcasts. If I don’t like the four presets, I can also adjust the sliders myself.
Only making calls when necessary
The Acefit Pro also has built-in microphones. So I can use them to make calls too; apparently, there’s even noise cancellation. I test the voice quality outdoors first. I’m on the phone in a light breeze, with cars driving past on the road. It’s not a pleasant experience for my colleague, with whom I’m speaking. I sound choppy, and at times I’m barely intelligible. The noise cancellation is doing its job in all the wrong places.
My second test takes place in the sheltered home office. However, complaints soon arise during a Teams call. I sound muffled and, again, somewhat choppy at times. I expected the Acefit Pro not to be able to keep up with the Jabra headset I usually use for office calls. But I hadn’t expected the difference to be so stark.
Lighting: Ambient lighting on the ear
I’ve found another nice extra feature in the app. Here I can control a lighting effect that Acefast has added to the headphones. A matrix of 40 LEDs in the headphones provides ‘ «’ ambient lighting». I can choose from eight colours that pulse between ‘ «’ ‘Fast Breathing’» or ‘ «’ ‘Slow Breathing’». The ear lighting isn’t just a gimmick; it makes me more visible when running at dusk or in the dark. The LEDs are surprisingly bright. You can spot me from a good ten metres away in the dark, or rather, you can see my glowing ears approaching.
Controls: Touch commands
I’ve got into the habit of selecting and starting my playlist before I go for a run. Operating headphones regularly baffles me: which side was the pause button again? Do I have to swipe or press to turn the volume up? Questions like that.
The Acefit Pro are neither better nor worse than others in this respect, just different again. There are four commands assigned to each side. They are triggered by a single, double or triple tap, as well as by holding down the touch-sensitive surface. A sound confirms that the command has been received. There is no haptic feedback, but this isn’t a problem.
In the default setting, I turn the music down by tapping on the left and up by tapping on the right. That works for me. I just have to be careful not to try to change the volume too quickly, because tapping repeatedly doesn’t make it louder faster – it just plays the next track. In the app, I can customise further actions if I want to, right up to activating Siri. Provided I have my iPhone with me.
Battery life: Enough for a long run
Weighing just 7.6 grammes per earbud, the Acefit Pro are lightweight. Nevertheless, according to the manufacturer, the battery lasts for six hours. Tested while listening to music in the office, I managed just over seven hours. Making phone calls drains the battery more quickly; the noise-cancelling chip may require more power here.
When jogging in the cold winter air, I use up around 20 per cent of the battery capacity in an hour. I know this so precisely because the Acefit Pro case has a double-digit display that shows the charge level as soon as I place the Acefit Pro inside.
Speaking of the case. Compared to an Apple AirPods case, it’s quite large, and rather slippery too. On a sloping surface, this oval thing slides straight away. Even if I just nudge it slightly, I’m afraid it’ll slip away from me like a curling stone. It’s therefore slipped out of my hand and fallen a few times. Luckily, the plastic is quite sturdy and hasn’t been damaged. I’ve developed a love-hate relationship with the case: I like the design, the fact that I can charge it via USB-C, that the earphones are held in place magnetically, and that it gives me up to 25 hours of extra battery life. Why on earth is it so slippery?
In a nutshell
Favourable challenger for Shokz and Co.
For just under 100 francs, I get a pair of comfortable, powerful and innovative headphones in the form of the Acefit Pro. The in-built lighting is more than just a nice gimmick; it makes you more visible in the dark. I really look forward to the Acefit Pro when I start my run because I can listen to my podcasts or some music with them and still hear enough of the outside world. I don't miss anything compared to the bone-sound models from Shokz that I usually use. I get the same functions and the sound quality is also good. And they're cheaper. A good deal! If you're not sure and are looking for a low-risk entry into the open-ear world, audio colleague Flo has written a guide.
