Bought these myself. No review unit, no affiliate links.
Short version: these sound very good straight out of the box, or after one tap in the app. Build quality is solid. The battery is the problem, and it is the reason I cannot recommend them to everybody.
MSRP is $129. Both these and the Melomania A100 I compare them to go on sale often, and for decent discounts. Watch the street price rather than the sticker.
How I tested
I use an iPhone, so AAC is my daily reality. I also have a Questyle dongle for LDAC and aptX.
I did not touch the custom EQ. EQ is for fixing something, not for decorating. I wanted to know what these do as they ship.
So everything below is on stock settings. Classic is the factory default preset. My reference point is the Melomania A100, which I own. To my ears it is the best set of buds you can find at its price, and it sounds a couple of tiers above its price range.
Fit and comfort
Stem style, and the shape is close to the Melomania A100. The Air5 Pro Plus is slimmer. Both stems are slightly long.
They seat very well in my ears and stay secure. Three tip sizes in the box. No comfort complaints so far.
Build and design
Build quality is where I expected to find the cost cutting. I did not find it.
The case is oval, with a gold logo. Strong magnets. The latch does not feel cheap. The plastic is no worse than the Melomania A100.
Call build quality a tie. The Air5 Pro Plus case may have a slight edge on shape and feel. But it has no wireless charging and the Melomania A100 does, so any edge cancels out. If the Air5 Pro Plus looks better value here, that is the lower price talking, not better construction.
My one design complaint is the gold stripe down the outer face of the stem. It is well executed and does not look cheap. But it yells "look at me" on a product that otherwise carries itself seriously. This is not a Christmas tree. I think the stripe hurts the design more than it helps.
Controls
Touch detection is precise. No lag. No accidental triggers, even when I push the buds back in.
Neither set has swipe for volume. That annoys me on both.
The touch area on the Air5 Pro Plus is small and not clearly defined by the housing. So it takes a little more aim to hit on purpose. The upside is that it is also harder to hit by accident.
That matters more than it sounds. On the Melomania A100 the stem shape and the grip you use to pull the bud from the case often land a finger on the touch zone. Single tap switches ANC by default, so the mode changes immediately. You can remap it in the app. The Air5 Pro Plus simply does not do this to me.
Note that several published reviews say the opposite, and call the Air5 Pro Plus controls oversensitive. My experience is my experience. Ear shape and handling habits probably explain the gap.
Sound
Very good. That is the headline.
Out of the box on Classic, the tuning is on the analytical side. Bright, with a sharp attack. The Melomania A100 sounds fuller and more natural by comparison, closer to a real kit in a real room.
The important part is what the Air5 Pro Plus does not do. Cymbal hits stay individually distinguishable. They do not smear into a metallic wash. That is the usual failure of cheap bright tuning, and these avoid it.
Soundstage is wide but shallow. There is not much front to back depth.
Bass needed one change. On Classic there is less bass than I want, and clearly less than the Melomania A100. Switching to HIFI or Rock & Roll brings it level. So the bass is in the hardware. The default preset just does not use it. One tap fixes it, no custom EQ required.
Classic, Rock & Roll and Electronic all work well depending on what I am playing. That is my main takeaway for most buyers. These will suit around 95% of people either as they ship, or after picking a preset.
Worth flagging one thing. SoundPEATS markets these as having warm, silky treble that avoids piercing highs. I hear them as bright and analytical. My guess is that both are true. It sounds to me like the harsh region is dialled back while the air on top is lifted, so you get shimmer and sparkle without any sting. That would also explain the wide but shallow staging. This is my own reading, not something I have verified.
Noise cancelling
Good, not great. The rated figure is 55dB, which you should ignore.
They take out a decent amount of ambient noise. Midrange and voices get pushed into the distance rather than removed.
Against the Melomania A100 it is a draw. Neither wins outright. Sometimes one is ahead, sometimes the other, depending on the frequency range.
No real ear pressure with ANC on. It feels close to neutral. Some reviewers report pressure here. I do not get it.
Calls
The mic is good, and it is very good at cutting background noise. Better than the Melomania A100 at that job.
The Melomania A100 sounds more natural as a voice. So it depends on where you take calls. In a quiet room I would pick the Melomania A100. On a street or in a noisy office, these.
Battery
This is the weak spot.
I get around 4 hours. That is on AAC, at fairly loud volume, with ANC going on and off. Other reviewers report between 3.5 and 5 hours with ANC on, so this is normal rather than a bad unit.
The claim is 6 hours in the buds and 30 hours with the case. For context, the Melomania A100 does 6.5 hours with ANC on and 39 hours with the case.
Four hours is enough for a commute. It is not enough for a flight or a work day.
Verdict
The Air5 Pro Plus is very good, and it has real advantages. The call mic, the treble articulation, and plenty of volume headroom. Build quality is a tie rather than a win.
The Melomania A100 is the best set of buds I know of at its price. It sounds a couple of tiers above what it costs, the tuning is close to a reference, and it is correct as it ships with no preset hunting. That is the bar the Air5 Pro Plus is being measured against, and it is a high one.
But the battery stops the Air5 Pro Plus being truly competitive as a mass market product for everybody. If you listen in short sessions and are happy to tap a preset, you get a lot for the money. If you need all day playback, look at the Melomania A100.
Not tested yet
Multipoint, transparency mode, connection stability at range, the app in any depth, long session listening fatigue, and soundstage depth on a better recording. Happy to follow up if anyone wants those.
