Product Review: Aftershokz Aeropex Headphones

In 2017 I wrote a review of the grandparent of the Aftershokz Aeropex headphones, the Aftershokz Trekz Titanium. In that review I commented on the durability of the Trekz Titaniums, noting that sweat and rain had not had an adverse effect.

Two years of regular use have proved me wrong. In that time I have made two warranty claims because transducers came loose. I suspect because of corrosion caused by the ingress of sweat into the transducer casings. To their credit, Aftershokz replaced both units via Distexpress Malaysia, which is their local distributor.

The successor to the Trekz Titanium is the Trekz Air which was introduced in 2018. The Trekz Air is 20% lighter than the Trekz Titanium. However, it has the same IP55 rating as its older sibling so I didn’t trade in my Trekz Titanium.

Aftershokz has just released its latest iteration of bone-conduction headphones. The Aeropex.

The Aeropex is IP67 rated which means it can be immersed in on metre of water for thirty minutes. That specification alone was enough for me to buy a pair.

The Aeropex (pictured lower left) is 30% smaller overall and 15% lighter than the Trekz Air (pictured upper right). Which makes it significantly smaller and lighter than the Trekz Titanium (pictured upper left).

I have used my Aeropex headphones for a month now. They weigh 26g and have a smaller neckband than the Titanium. Which makes the Aeropex very comfortable and fit better under my cycling helmet. Sound quality is more dynamic with enhanced bass. Sound leakage is decreased and the transducers vibrate less against the skin.

Another difference between the Aeropex and the Titanium is the use of a magnetic charging port rather than a micro USB port. The magnetic charging port features a moisture detector which alerts you if there is sweat or other liquid on the port. Charging the headphones while the port is wet can damage the circuitry.

Included accessories are a rubber case with a magnetic clasp and two charging cables.

I bought the Cosmic Black version. The Aeropex comes in three other colours.

At current prices, the Aeropex costs twice as much as the now discounted Titanium. Is the Aeropex worth the money? Definitely. The Aeropex boasts improved comfort, sound quality and an IP67 waterproof rating. An important plus is that Aftershokz is the only bone conduction headphones brand offering a two-year warranty.

I gave the Trekz Titanium headphones a five-star rating. The Aeropex deserves six stars.

    The Aeropex i have got corrosion on the power terminals. I always use the headphones during bike rides or runs.
    It encountered charging issues until it was totally not charging. Aome bulging on the terminals until it chipped off. Closer look shows that it got corroded. I think it is definitely not IP67. It’s likely that perspiration seeped through the components. Did not last for a year.
    I can send you the photos i took.
    I love these earphones and i hope they fix it. Maybe just seal it with some kind of waterproofing.
    Until then I will not buy a replacement.

    • I’m sorry to hear that your Aeropex is damaged.

      Hopefully you can get a warranty replacement.

      I had issues with sweat ingress into the transducers of the previous model – the Trekz. Fortunately, I got a warranty replacement.

      I’ve had my Aeropex for more than two years now. I ride in hot and humid conditions. It was 40ºC last week. Sometimes I ride in the rain, too. No terminal corrosion problems – yet.

      I think one of the things to watch for is that the terminals are not wet before you attach the charging plug.

        It is the 2nd unit. I sent back the first one to the store. I got this as warranty replacement but it also encountered issues. I think it is not suited for tropical weather like here in the Philippines. I use it on long rides. Usually hot days and I sweat a lot. The product needs to be sealed better on the power terminals. Maybe a conformal coating. I hope it gets to the factory or design engineers to consider.
