Acefast AceFit Air Earphones Review: Open-Ear Design with Surprising Quality

Open-ear earphones have always been a bit of a mixed bag for me. Traditionally, they lack the bass and immersive sound that in-ear or over-ear headphones provide. It often feels like standing in a room with a speaker echoing in the background rather than being enveloped by the audio.

That said, open-ear designs haven't been without their charm. For podcasts or casual listening, they can feel natural—a bit like the sound is happening in your environment instead of sealing you away from it. Enter Acefast's AceFit Air earphones—a lightweight, open-ear design that aims to strike some balance between sound, comfort, and looks.

What Is "Open-Ear"?
"Open-ear" is a designation for earphones that rest near the outer ear rather than going into the ear canal. The AceFit Air uses this concept with a soft silicone structure and a titanium-nickel memory wire built into the frame for added strength. At a mere 7.5 grams, they're very lightweight and rest well on the ear—after you figure out how to put them on properly.

They do take some getting used to, especially if you're coming from traditional in-ear or over-ear headphones. But once on, they offer a decent fit for daily wear.

Comfort & Fit
If you're planning on using these for running or exercising, it's a bit of a toss-up. They're light, but they do shift a little bit when running. I'd give them 6 to 7 out of 10 for running comfort. For general wear, however—computer work, gardening, or simply walking around—I'd say they're a comfy 8.5 out of 10.

As with all open-ear devices, fit is going to be different for each person. They were comfortable for a few of my colleagues; others said they felt a bit loose. It just depends on your ear shape.

Sound Quality: What to Expect
Sound-wise, the AceFit Air delivers a standard open-ear experience: it's like music is coming from the same room rather than in your ears. You're still highly attuned to what's going on around you, which is ideal for outdoor or multitasking listening.

The 20 x 8 mm drivers provide decent clarity on the highs and mids and are ideal for podcasts, acoustic tracks, or background music. That Achilles' heel of open-ear tech is still present, however—low-end bass performance. If you're a basshead, these might not be your thing. You won't get that satisfying "doof-doof" from bass-heavy music.

The silver lining? You can tweak the EQ settings in the companion app. I would strongly recommend doing that if you prefer a warmer or punchier sound.

Privacy & Sound Leakage
Worried about others being able to hear your audio? At low volumes, leakage is minimal. At anything above 40% volume, though, some sound does leak out—so maybe don't play anything embarrassing when you're out in public. That's just one of the sacrifices you make with open-ear devices.

Touch Controls & Usability
The AceFit Air has touch-sensitive controls that function the same as most premium earbuds:

1 Tap: Volume

2 Taps: Play/Pause or answer call

3 Taps: Skip forward/back

Hold both: Voice assistant

The sensitivity is slightly too high, and I did inadvertently trigger a command when adjusting the fit on occasion, but you can remap these controls in the app—which is a nice bonus.

Battery Life & Charging Case
The charging case is compact and sleek—a bit of a flattened macaron (or "smackaroon," I joked). It's soft to touch, fingerprint-resistant, and has a USB-C charging port.

6 hours of playback time per charge (at ~50% volume)

Up to 18 additional hours with the case

Quick charging: 10 minutes provides approximately 2 hours of playback time

The earbuds magnetically snap in and pass the shake test, so it's okay to throw them in your pocket worry-free.

Durability & IP Rating
These earphones have an IP54 rating, which makes them resistant to dust and splashes—a great fit for sweaty sessions or a light drizzle. Just don't take them for a swim!

Final Thoughts: Worth It?
The AceFit Air is a great open-ear entry-level earphone with semi-premium construction and surprisingly good quality for the price. It's not going to satisfy bass heads, but for people looking to:

Listen to acoustic music or podcasts

Be able to hear what's going on around them

Use an inexpensive, comfortable, and stylish set of earphones

—that these are a good option.

They are available in black and white, and although I have the whites, I think the blacks are a bit sleeker. I've left updated links to both down below, so be sure to look out for the best available deals.
