1More Aero review: budget-friendly head-tracked spatial audio on a budget

1More Aero: Two-minute review

1More is an audio tech brand that hasn’t produced devices on a par with big names such as Sony, Bose or even JBL – at least not yet. But over the past few years it has been releasing both over-ear headphones and true wireless earbuds that have held their own in a crowded market, including the 1More Evo, 1More Sonoflow and 1More ComfoBuds Mini. So how do the 1More Aero true wireless earbuds compare? 

The good news is that the 1More Aero true wireless earbuds are the definite step up from 2022’s 1More ComfoBuds Pro that 1More claims they are. They’re solid all-rounders that offer an impressive set of features for their price. I enjoyed the good overall sound quality on offer, ANC works well and battery life is… fine. I also liked the fit and the tapered stem design that 1More first debuted with the ComfoBuds Pro – although that’s down to personal preference.

However, there are many true wireless earbuds to choose from these days, from the best true wireless earbuds your money can buy through to the best budget wireless earbuds for those who want a cheaper alternative. So what sets the 1More Aero apart from the rest? The answer is spatial audio, which makes it seem as if you’re hearing sound from all around you in a three-dimensional space – and crucially here, it even alters you turn your head from the source device.

There’s a lot to love about the 1More Aero buds, but spatial audio for around $100/£100 is the main selling point here. But although I certainly enjoyed listening to my favorite tracks with spatial audio switched on, does everyone really need spatial audio? Read on to find out more in this 1More Aero review. 

1More Aero review: Price & release date

• Cost $109.99/£99.99/around AU$182
• Released in October 2022

The 1More Aero true wireless earbuds were released in October 2022 and cost $109.99/£99.99/around AU$182. Hovering around the $100/£100 mark makes the 1More Aero a similar price compared to rivals and they just qualify for TechRadar's best budget earbuds category. However, the competition is pretty fierce at this level. 

The most obvious competition comes from the Earfun Air Pro 3. TechRadar also described these buds as good all-rounders and they cost $99/£99 at launch – although you can find them a little cheaper now. The Air Pro 3 buds offer a similar sound and ANC experience, as well as a significantly longer battery life, but you won’t get spatial audio. 

To get the spatial audio feature you’ll find in the 1More Aero, instead you’d need to spend significantly more for alternatives, like the LG Tone Free T90Q ($229.99 / £199.98) and Sony WF-1000XM4s ($279.99 / £250 / AU$449.95). More on whether the 1More Aero buds perform at the levels of these higher-end options soon…

1More Aero review: Specs

1More Aero review: Features

• Head-tracked spatial audio is the star of the show
• ANC works well 
• Smart Loudness tech is handy

Before I even put the 1More Aero to the test, I was impressed with the range of features on offer here, many of which can be tweaked within the 1More app, which I found clear and easy to use. 

The first noteworthy feature is ANC. During my testing, I found noise cancelling to be generally impressive. There are four levels of ANC to choose from, but I opted for the highest level ‘Strong’ the most often. Because why put ANC on if you’re not going to put it ON, right? Although if you work in an office and need varying levels, the choice might be handy for you. 

ANC was effective, drowning out conversations in a coffee shop completely. Difficult, higher-pitched sounds, like an alarm and toddler screaming, were muffled but still audible. And deep rumbling sounds, like a train and a fan, were still detectable a little, but everything was significantly dulled. If you’re looking for buds to simply lessen the chatter at work, these will do nicely. There’s also a transparency mode, which is handy for conversations, but I found it easier to just pop one of the buds out instead of faffing with my phone. 

Something I haven’t seen before is a Smart Loudness feature, which you can switch on and off and then use a slider to amp up. This is to keep the bass, mids and trebles detectable at low volumes, but it was hit-and-miss. If you listen to music at lower volumes it’s worth turning on, especially to reintroduce bass, but it wasn’t a feature that wowed me.

You can control the buds via touch controls on the stems and you can customize what these do via the app – although there’s no option to decline a call. These controls worked well most of the time, but sometimes weren’t as responsive and sensitive as I'd have liked. I found myself getting my phone out to make adjustments instead.

Within the app (oddly, under 'Experimental Features') there’s the option to switch on multipoint pairing, allowing you to move between audio input devices. Although there was a slight lag as I switched between a phone and a laptop, it did work and it’s a feature that’s incredibly handy – especially when working on my laptop, then taking a voice call on my phone, then moving back to the laptop to listen to music or join yet another video call. 

In terms of battery life, you’ll get 7 hours from the buds with ANC off and 5 hours with ANC on. I found these estimates from 1More to be bang on during my testing. You can get 28 hours in total from the case and buds combined, with ANC off. That’s a decent amount of battery life, but can be bested by similar-priced rivals, like the EarFun Air Pro 3 that gives you 9 hours from the buds and 36 hours from the case with ANC off. Or the JBL Live Pro 2 buds, which offer 40 hours of listening time in total. And TechRadar's pick of the bunch here is the far cheaper Cambridge Audio Melomania 1 Plus, which will bag you 35 hours in High Performance mode, or 45 in Low Power mode… 

• Features score: 5/5

1More Aero review: Sound quality

• Enjoyable sound
• ANC isn’t great but it’s good enough
• Spatial audio is fun – especially for TV, movies and games

Overall, I found the 1More Aero buds an enjoyable listen. I felt that way across the genres too – noting a really nice balance, with crisp highs and crystal clear vocals, underpinned by more than enough bassline rumble underneath when it was needed. 

There was a real smoothness and warmth to some of my favorite tracks, too, like Tango by Onyx Collective. When I listened to big, classical tracks, like Johann Johannsson’s score for Arrival, I occasionally yearned for a wider, more expansive listen, which I've experienced with other buds at the level (see the Honor Earbuds 3 Pro). But I was impressed with the power and bass these little buds delivered through their solid low end, handling such epic and eerie instrumental tracks well.

You can tweak the sound, too. Within the 1More app there’s an equalizer you can manually adjust, as well as a bunch of EQ presets, including Studio and Classical. I enjoyed testing some of these and recommend you do the same, although some seemed a bit heavy-handed. Case in point: Bass Booster with Latto x Mariah Carey’s Big Energy made the bassline sound, well… a bit silly, like I was listening to a boomy sample track on a keyboard. The same goes for Vocal Booster, and Pop, which was very tinny. Then again, putting Bass Booster on for the Arrival soundtrack actually added to the drama. The lesson here is, you’ll need to play around with the settings to see what suits you – and you might need to do that each time you switch genres. 

On the subject of settings, switch spatial audio on and you’re in for a 360-degree sound treat. I mostly felt as if positional audio was accurate, so sounds came from a central stage or instruments around me. There’s head tracking here too, which essentially means that as well as feeling like sound is all around you, to some extent, you’re moving around it too.

I probably enjoyed spatial audio the most when watching TV shows and movies. For example, I watched The Mandalorian with the 1More Aeros and replayed a scene when the Razor Crest landed with and without spatial audio. It was subtle, but definitely created more of a cinematic, stereo sound feel than I'm used to.

Back to music, putting on spatial audio halfway through De La Soul’s Supa Emcees and selecting the Hip-Hop EQ preset was a pleasing upgrade. The track came alive more than ever. It might sound a bit cheesy, but it genuinely felt like I’d gone from listening to a track positioned directly in front of me to hearing it performed on a stage above me – exactly what you want from spatial audio. 

I felt the same about pop music. Miley Cyrus’ Flowers was noticeably elevated with spatial audio switched on. I then chose the Deep preset for added bass and Studio for a more neutral listen. The energy of this track was simply phenomenal. The best earbuds can help you notice things about your favorite tracks you haven’t before. 

Having said that, not all music was as sparkly and elevated with spatial audio – even tracks optimized for it – and I did prefer the spatial audio experience with other buds, like the LG Tone Free T90Q, as they provided a more consistent and convincing sound. Then again, that was for almost double the price. 

I did wonder whether the wow factor of spatial audio had already faded. This might be because, other than the EQ settings, you can’t change anything else about how spatial audio or head tracking works, which it would have been nice to adjust. Then again, this is an affordable application of spatial audio, so I really am being picky.

1More Aero review: Design

• Teardrop design 
• Light at 4.9g per bud
• They stay put

Like a lot of true wireless earbuds on the market at the moment, the 1More Aero buds have a stem-like design. At first glance they may look very similar to other buds, like the Apple AirPods Pro, but they’re a little different in that they’re teardrop-shaped with tapered ends. I like this small design quirk when other brands are just copying and pasting the AirPods design, but appreciate they may not be for everyone. 

The buds are light at 4.9g each, which makes them easy to wear for long periods. In fact, I had no trouble keeping them in for most of the working day and you have S, M, L and XL tips to choose from to find the perfect fit. The silicone tips I selected created a decent seal. They came a little loose when I wore them for more than 30 minutes, and I did knock the stems a couple of times, but this experience was no different to all of the other true wireless earbuds I’ve tested. 

There’s an IPX5 rating here, which means these buds are not fully waterproof but are certainly sweat-proof and rain-proof, which makes them a good option if you’re looking for a pair of workout buds. Although they did budge enough for me to keep securing them during a jog and when I was trying to perfect my downward-facing dog, although not enough to fall out.

The buds come with a charging case that’s small enough to slide into a pocket and weighs 45.2g. It has a clamshell-style design which I personally prefer to the pill-shaped box that seems to have become standard from rival brands. My only criticism of the case is the magnets that keep the buds in place could have been a bit stronger, they felt weak compared to similar devices I've tested.

• Design score: 4/5

1More Aero review: Value

• Cheaper buds offer improvements in some areas
• You’d have to pay much more for spatial audio

As a whole package, the 1More Aero buds are good value. They offer everything most people need from a pair of buds, including good audio and ANC, decent battery life and a comfortable fit. However, in some areas other buds shine. For example, if you want a longer battery life or a bump in ANC, there are better alternatives at a similar price – look to the Honor Earbuds 3 Pro or JBL Live Pro 2 for starters. 

That said, if you want that top-tier spatial audio feature, you’d have to pay significantly more. So in that respect, they’re great value. The question you need to ask yourself is: do you really need head-tracked spatial audio? It’s fun at first, and certainly improves the experience of TV shows and movies, but I'm not convinced it’s a must-have for everyone. 

So are the 1More Aero good value? That entirely depends on what you’re looking for.

1More Aero review: Also consider

JBL Live Pro 2
Pay a little more and you’ll get slightly improved ANC and better battery life with the JBL Live Pro 2. A good alternative if you don’t like the tapered stems of the Aeros, but don’t want to pay the big bucks for true wireless buds. There's no spatial audio though. Here's TechRadar's JBL Live Pro 2 review.

Earfun Air Pro 3
We’ve mentioned these rivals several times, but they bring you a similar experience in terms of audio and ANC, as well as a better battery life for less. They’re less interesting to look at though and don’t pack in spatial audio. Here's TechRadar's full Earfun Air Pro 3 review

How I tested the 1More Aero

• Tested for 7 days
• Used working at a coffee shop, while working out at home and on a few bus and train journeys
• Mostly tested with Apple Music and iPhone 13 Pro

To test the 1More Aero buds, I took them with them everywhere over the course of a week. They came with me while working at a coffee shop, on long walks through a town, on the bus and train to meetings and kept me occupied during workouts, too. 

I’m always keen to see how true wireless buds fare over long periods, so I can really test their comfort levels and make sure the battery claims are accurate. So I kept them in for hours on end, while going from working to walking to working out. 

I mostly used the buds to listen to a range of playlists on Apple Music, but also used them to listen to audiobooks, stream podcasts and watch a few TV shows – a good chance to see how spatial audio compares with different types of sound.

I’ve been testing audio products and wearable devices for around ten years now. I like to focus on how comfortable tech is and how easy it is to use.
