Review: Acefast Acefit Air: Shockingly Good for the Price - I’ll be honest—right out of the box, the sound quality felt pretty mid. Then I downloaded the Acefast app and used the custom equalizer. Whole different story. With a few tweaks, the headphones absolutely came alive, delivering punchy sound that rivals way more expensive sets. Fit and comfort? Excellent. They’re feather-light, and after a few minutes I barely notice I’m wearing them. The open-ear design hits the sweet spot: loud enough to cut through gym noise but still keeps my situational awareness. I thought their weight might mean they’d fall out, but nope—these little champs stay put. I’ve worn them through full-body lifting sessions and treadmill runs without a single slip. I haven’t stress-tested them on CrossFit-style HIIT yet, but based on what I’ve put them through, I’d bet they’d hold up. The build looks and feels high quality, and for the price, they punch well above their weight. I’ve owned Bose Soundsports that cost over $200, and honestly? I’d take these Acefasts over the Bose. Bottom line: excellent headphones for the price, with the comfort and performance to back it up. Highly recommended.
Review: Pretty good product - I got this product as part of a test group with AceFast, just to be upfront on how I obtained the product. TLDR; This product has really good sound, the multi-function key is a bit wonky to touch, but very responsive and simple enough to use. My ears don't hurt from using it anymore than normal earbuds do, and they really stay on when doing activity. Overall a pretty good product. I have gotten AceFast products before and was not exactly impressed. However upon testing the Pro Air, the quality of the sound is surprisingly good for it being over your ear. I was hesitant to try it considering I have always had issues with over earbuds never staying on properly and being uncomfortable to wear. These feel super lightweight, don't push onto my ears awkwardly and overall do not have discomfort anymore than normal earbuds would, if not possibly tolerate more extended use. I was a bit unsure how to place them, but the indicators were obvious on the inside of the actual sound bud which is supposed to be placed right on top of of the earhole sort of resting on the tragus. A downside is if you wear glasses regularly, its not comfortable. I wear glasses and tried putting them on and it just felt uncomfortable. Which isn't surprising really, but even with this sleeker design it can't be helped. As for the multifunction key the commands are simple and the app actually lets you customize the commands if you so need it, which I think is pretty nice in terms of accessibility. I did not explore that too much as I was pretty satisfied with the current set up. It was a little weird to try and find the button which is more of a touch sensitive pad than a click button. The diagram does show you where it is located. As for the app itself it's simple enough. There were some connectivity issues with accessing the device's interface while in use. You can customize the sound and there are 3 presets which are pretty nice. It also shows the battery life, and I think it's about as long-lasting as most earbuds on the market so nothing overly surprising, but not disappointing at all. The case is flat and magnetic which is nice and easy to slide into a bag without it being bulky. Charging cord is a standard USB C to C, so if you don't have a plug for USB C to outlet that might be a downside. Overall I'm pretty happy with it! I've worked out with it and I was actually considering overhead headphones for working out, but this honestly feels much better to have. I can do more dynamic exercises and don't have to worry about it fall out at all, it's stayed on without budging. Suggestions for manufacturer: I think the app would be nice for all new AceFast devices to be able to customize the sound output, and even having more presets for more dynamic sound depending on genre of music.

### ⭐⭐⭐⭐ Great sound, bad touch controls, price is meh
*by K***L on January 29, 2025*

TLDR: great sound, mostly secure ear placement, touch controls could be improved, battery very good, price not very competitive I want to start out by saying that this company is excellent and I have two of their other earbuds (acefast T9 and acefast crystal T6). Their customer service is excellent, and normally, I would review at 5 stars, but with these there were just a couple of issues. 1) the first pair I bought would not connect or charge. They would go on when I opened the case, but once removed, the would immediately go dead. So that first impression was not great. However, when I contacted customer service and told them, they immediately apologized and sent a new pair. For that, they are really awesome. The new pair immediately paired and work great 2) Fit: they fit easily over the ear, and feel like you're not wearing anything at all. Very weird at first (I usually where in ear or bose type over ear headphones, so it took adjusting), but very nice after long wear (no heavyness or ear fatigue) 3) Sound: the sound and volume are both great. They are easily heard at a low volume, and also feel like the sound is right in your ear, even though the are technically not in your ear canal. 4) Touch controls: the touch control drives me a little insane. These are very sleek and light, but the touch control portion of the ear bud is also where you have to touch to put them in your ear, so any time you are putting them on or adjusting them, you will set off the touch controls which will either pause, play, or increase your volume. 5) case: case is slim and very cool looking. Charge port is on the bottom, which makes charging slightly awkward, but no big deal. Case is magnetic to hold buds in, and they hold and charge very securely 6) look: they look very cool and futuristic. They're very light and sleek. 7) Price: honestly, for a price of $80, I would expect no issues and better, less reactive touch controls. I own over ten pairs of wireless ear buds, including noise canceling buds and ones that last for 10 hour charges at a time, and only one cost near $80. I just think the market is a little too competitive for the price tag. Overall, good sound, very light, decent battery. But touch controls and price, not my favorite
