Before we get into this review, you can view our testing process guidelines by heading here.It outlines how we test the headphones, and what we typically look for.

The Specifics

Who: AfterShokz is an audio company offering "consumers a more comfortable, healthy and safe listening experience."
The product: Trekz Air, bone-conduction headphones.
What comes in the packaging: USB charging cable, ear plugs, and a carry case.
What are they selling us: AfterShokz believe these headphones provide "maximum situational awareness and comfort" and a "premium audio experience."

The Design and Build

Given the wraparound nature of the headphones, it's hard to consider the Trekz Air a thing of beauty, but they don't go out of their way to make you look like a doofus, so we can't really fault them on that front (the controls and charging port sit nicely too).

On the subject of build quality, despite their lightweight construction, they're weighted in all the right places. While you could argue this should be a 'comfort' consideration, the fact that they feel so robust is reassuring.

The Comfort

Give it five minutes and you'll forget you're wearing these. Seriously. They're so light, they just sort of vanish once you put them on. That's part one of why these might be the most comfortable pair of headphones you'll ever try. Part two is down to the fact that they're bone-conduction headphones, which means they sort of sit next to your ear, rather than in them. No fiddling with ear-tips to find a decent fit, or adjustments needed while you're moving, they just hook on your ears. That's it. You put them on and then you forget about them.

The Sound

AfterShokz Trekz Air bone-conduction headphones

You'd expect a premium sound for £149.99, wouldn't you? Not an audiophile-grade sound, but certainly a sound verging on 'luxurious'. Sadly, you won't find that here. If I was to evaluate the price (£149.99) and assign a percentage to what the 'sound' brings to the conversation, I'd put it at 30%. Now, I can picture a bunch of you clocking out at this point, but stay with me. The sound is still way above average, you just need to come at this from a slightly different angle.

These headphones were designed to keep you engaged with your surroundings, which is a terrible selling point for most headphones. However, if you're a cyclist, being aware of what's going on around you while also listening to Carly Rae Jepsen, should be considered a good thing. Or if you're out for a late-night run. Or any other form of exercise which has an element of 'danger' to it. Add that to the above sections ('Comfort', in particular), and you might start to get an idea of what your hard-earned money will get you.

I was expecting a soundstage lacking bass, but thankfully the sound is pretty even across the board (there's an obvious spike in the highs, but it's not off-putting). The biggest issue occurs when you max out the sound, as the vibrations in the headphones cause a tickling sensation, which to some might be a good thing, but for me, not so much. Sound-leakage is minimal, so you could use these in a commuter setting, though the idea of hearing hundreds of conversations at once, while also listening to Carly Rae Jepsen (Carly always), seems a bit crazy to me. AfterShokz have tried to get around that by supplying some earplugs, but I can't imagine a scenario in which I'd do that.

Six hours of continuous music and calls on a single charge is on the low side but should be more than enough for the average person.

Did we mention these are bone-conduction headphones? That seems like a pretty big thing to mention here. The sound is delivered through your cheekbones. Your cheekbones. It's 2018, but you put these on and it's suddenly 2088, ya know?

Is It Worth The Money?

If you're looking to replace your current everyday commuter headphones, then these probably won't be worth splurging on, but if you're into running, or cycling, or any number of sports - and consider comfort and safety key points - then you won't find a better pair of headphones.

You can purchase these headphones by heading here. They retail for £149.99.
