Aftershokz has been in the running headphones game for a few years now, and in that time it’s had one goal; to build open ear headphones you can run, cycle and and work out with, all without entirely blocking out the world around you.
It’s gone all in on bone conduction technology built into an over the neck design to do make that happen. With its latest, the Aeropex, it’s managed to wrap that tech in something that’s slimmer and more durable, all while adding new bone conduction tech to improve sound quality.
They're more expensive than its Trekz Air headphones, which launched back in 2017. For runners particularly, Aftershokz have fast become the go-to option as more races impose bans on the use of closed headphones and in-ear headphones due to safety concerns.
With very little competition in that sporty open ear headphones space, the Aeropex look to have cemented Aftershokz’ place as the number one pick for fitness lovers once again.
Price and availability
The AfterShokz Aeropex are available to buy now directly from the company’s website and a whole host of online retailers including Amazon.
They're priced at $159.95 / £149.95 (about AU$240) making them the most expensive option to go for in the Aftershokz family. As mentioned, that’s $50 / £50 more than the Trekz Air and $20 / £20 more than the Aftershokz Xtrainerz, which are waterproof headphones that offer a built-in music player but no Bluetooth streaming.
With every new iteration, Aftershokz has successfully managed to shave a considerable amount of weight off the frame and the vital parts of its headphones, to make them lighter to wear and less noticeable when you’re on the move. Put the Aeropex up alongside the Trekz Air and you can appreciate how much slimmer things have really gotten here.
Aftershokz says they're 30% smaller and 13% lighter, and while those sound like small numbers, the difference is very obvious as soon as you pick them up. These are considerably lighter than the last generation. It’s still the same neckband-style look, but it’s significantly reduced the size of the arms that sit just in front of your ears. The frame is skinner too.
Things have been upped in the durability stakes moving from an IP55 water-resistant rating to a IP67 rating. That means you’re getting something that’s equipped to be submerged in water up to one meter depth for 30 minutes. In reality, that rating is about doing a better job of fending off sweat and increasing its chances of surviving for a run in the rain and maybe dropping them in a puddle on the way as opposed to taking them for a swim. Bluetooth and water don’t mix anyway, so there’d be no reason to take them to the pool.
We did manage to brave a storm with them and get them sweaty for some indoor bike and rowing sessions and we are happy to report they’ve survived to live another day.
The skinnier, bendy frame did though have us question the durability, though. There’s always been a bit of a question mark over how robust Aftershokz headphones are long term, and we’ve actually had some break on us in the past.
Fortunately, that’s not been the case with the Aeropex, and there hasn't been any worrying signs of wear. Though for peace of mind, we’d suggest placing them in the accompanying case as opposed to simply slinging them in your gym bag to make sure they do go the distance.
In terms of onboard controls, there’s two grippy physical buttons tucked away on the underside of one of the sides of the frame next to the charging port. They are predominantly used for turning the headphones on and adjusting the volume. On a run, those buttons still a feel a bit too close together, which makes swiftly turning things up or down can take a couple of attempts. There could be more done more to help distinguish between the two.
The charging port has changed from the covered USB one that we got on the Air to something that’s now proprietary. While that does mean you now have to keep hold of another proprietary charging cable (there’s actually two in the box), the move has meant Aftershokz can offer that increased waterproof rating to give the Aeropex that durability boost.
If you’re all about colors, there are more options to choose from this time too. We had the Cosmic Black model to try out, but there’s also a pick of red, blue and grey designs to choose from, and all come in at the same price.
There’s the promise of improved battery life here with the Aftershokz Aeropex. You’re now getting eight hours of music playback and talk time, which is up two hours on the Airs. It also takes just one-and-a-half hours compared to two hours to fully charge up.
You’re now also getting an hour of music playback from a quick 15-minute charge. When you first turn the headphones on and tap the buttons, it’ll give you an status update on battery life to give you a heads up when it might be time for a spell on the charger.
If you’re in the gym for an hour a day or running for around the same amount of time, that’s plenty of battery to play with for the week ,and that’s pretty much what we found.
Aftershokz headphones have fallen a little short of those claimed battery lives in the past, but they seem to fair a lot better and more reliably on the Aeropex. That fast-charging option is a great addition too if, like us, you constantly forget to stick them onto charge when they have run out.
As we said, bone conduction technology remains at the heart of how Aftershokz delivers audio, in a way that doesn’t entirely distract you from the world around you.
The way that bone conduction tech works hasn’t changed for the Aeropex, using transducers to guide through vibrations up your cheek bones and to your ears, to deliver sound without needing to have something sitting directly inside of your ears.
What has changed is what Aftershokz refers to as ‘PremiumPitch 2.0’. This time it’s using the transducers to channel those vibrations that are angled to sit better on the cheekbone, promising to deliver sound that possesses more bass, less vibration and less sound leakage.
With the first generation of Aftershokz, those issues were very prominent. You didn’t get a lot of power, they vibrated at higher volumes and they leaked a fair bit too. On the Aeropex, progress has certainly been made in some areas, but not in all. You are obviously not going to get the kind of results you’d expect from an in ear or over-ear headphones, but there are some noticeable improvements with the very gentle upping of bass, improved detail and overall upgrade in audio quality.
Those improvements are more noticeable at moderate volume levels. Venture in the gym or for an run outside with them, and those improvements do shine through. Unlike previous models, there’s a better balance between letting you hear the real world and letting your hear music or podcasts with more satisfying sound.
There is undeniably plenty of room for things to get better as that bone conduction tech improves, both in bass and clarity, but the differences between the Trekz Air and the Aeropex are noticeable.
Interestingly, there are ear plugs also included, which you can use to improve sound quality. It’s similar to what Aftershokz does with its swim-proof headphones, and it certainly has the desired effect of providing something more rewarding. You just have to be willing to plug your ears up, which does pretty much defeat the purpose of open ear headphones.
If you like breaking away from your workouts when a call comes through on your phone, there are dual, noise-cancelling mics to pick up your voice. You should have no problem taking those calls, though don’t expect exceptional levels of clarity here.
You still get a little of that vibration sensation at higher volumes though it’s been dialed down a little and it doesn’t ever feel uncomfortable or to a level that you’d want to stop using them. They also do seem to leak a lot less at more moderate volumes, though it’ll still be the case when you crank things up to the max.
If you’re looking for headphones that are primed for getting sweaty with and you don’t want to drown out the world, the Aftershokz Aeropex are currently your best option. From a design point of view, big strides have been made from the Air and those first generation Aftershokz headphones. They feel nicer to wear and the shrink in size does make a difference from a comfort point of view.
If we’re talking about sound quality, then the Aeropex don’t go leaps and bounds beyond they're predecessors, though they do show some subtle improvements, particularly in terms of clarity and bass.
They are $50 / £50 more than the Air, and for us the big difference is the design and the battery life. If you desire that extra time to use them between charges and something that sits lighter on the head, these are the ones to go for.
Right now, Aftershokz owns this space because there’s nothing really out there to give it some competition. Hopefully that’ll change in the future because there’s definitely an opportunity for others to push bone conduction tech even further.
