Pros:
-Light weight
-Able to hear outside sounds
-Long battery life
-doesn't bounce while running
-comfortable
-sounds better than the cheap knock offs
Cons:
-Can't skip back in tracks with the headphone buttons, my cheap ones could do that at least.
-A bit pricey but I so was the cheap ones that died after 8 weeks. I guess I'm just used to 9 dollar ear buds. Lol.
Now to address the sound quality issues that people complain about. Yes compared to over ear headphones and in ear ear buds the sound quality of these suck. But these aren't traditional headphones. These are bone conduction headphones that are meant to allow you to hear outside sounds for your safety/awareness. Yes they do leak sound and can be heard buy people near you if you have them cranked up loud. This is not an issue with me because I just keep mine loud enough to hear the music. I can still hear my foot steps and breathing while running. Yes these are bone conduction. They come with ear plugs so you can block your ear canals. Even though this defeats the purpose of open ear headphones I guess some people will use the ear plugs. And the funny thing is that when you block your ear canals the sound quality of these headphones goes way up close to in ear canal ear buds. I can't really explain this but I would assume it's something to do with sound waves out of sync where you can feel and hear these at the same time.
Now for my conclusion.
As a runner I'm not too concerned with my music quality. I don't even really listen to the music that close. It's mostly for the beat that I will change to whatever pace I want to run. Also a lot of 5k and other events are starting to ban headphones. My last 5k I ran just 2 weeks ago said no headphones. Not wanting to argue with anyone about why mine are different I just kept them in my pocket until I got around the first turn then put them on. It's not like they are gonna chase me down. Lol. Anyways these are great and have lasted longer than my last cheap set. I will update this review down the road, no pun intended, and let you all know how they are holding up.
9 month/250+ mile update:
These are still holding up great. No problems whatsoever in the last 9 months. I've ran in pouring rain with them, dusty gravel trails, freezing temperatures, and 90+ degree days. They still pump out the tunes. I haven't even noticed any reduction in battery capacity but I only charge it maybe once a month.
There are other competitors out there with similar features. I haven't tried them, so I don't know how they compare. I can say it is hard to beat the Titanium experience, so unless a friend tries some other company's product out and lets me compare AND if I have surprising results, I'm not going to switch. I'll use my AfterShokz Air for as many years as I get from them because they are cool and work, but I won't buy another Air headset without some compelling new experience.
I will buy the Titanium model again if my Air headset ever has a problem.
These headsets are not for everyone. They don't cancel out ambient noise. If you want that, they include earplugs, but what's the point then; just invest in good earphones that cover your ears. I hate having my ears covered. I hate having things stuck in them even more. For me the ideal experience is having a headset that is very hard to overhear, on my temples, that delivers great sound from Bluetooth at a distance. Air is half of that. When they are working perfectly, they rock. They're light and comfortable. They just suck in comparison to the other product the same company offers (in my experience). Still, I would rather use these than my noise cancelling headphones. If compared to ear buds, they're 1,000% better (for me)! But add another zero to that improvement if I can get clear audio from more than an arm's length away.
Top reviews from other countries
I've listened to podcasts and music on these. It works very well for both situations.
I've been running with a beanie hat and it works just fine with hat or glasses. In fact, I think it works better with the hat since it presses it against the skull for better sound transmission.
These also have an interesting feature: if the control button is pressed three times, it will dial the last number that was called. Since I run early mornings when it is dark and roads are sometime icy, I make sure before I leave to have my home number as the last number dialed. This way I can make a call in case of emergency without having to reach for the phone
I was highly impressed at how well it worked while biking, not only do you have the situational awareness, the wind doesn't affect these like they would my AirPods. I'm able to listen comfortably at 75% volume. In situations with higher background noise however (standing at a busy intersection), due to the obvious lack of sound cancellation, it becomes very difficult or impossible to hear from these, although that would probably be true if you were wearing AirPods as well.
Battery life is excellent, I'm able to use it a full day (on and off use, not playing stuff the whole day) however it does take a while to charge (~1.5hrs to full).
The design has two drawbacks for me, the over ear hook can start to hurt the back of my ear after a few hours of wearing it and the loop around the back means you cant wear it while lying down. The over ear hook does not however obstruct me in any way from using any of my sunglasses or helmets.
I’ve struggled to find the right set of headphones, the Apple earpods have served me well but end up breaking because of sweat (minging). I had the same problem with Bose sports headphones having them replaced three times.
I tried a couple of wireless headphones and had issues with sound isolation (dangerous), wind noise and that weird thumping everytime your foot strikes the ground.
So I thought I’d try these. I’m really glad I did.
Very easy to setup, battery will last 4 or 5 hours, and they fit so well you forget you are wearing them - on my last 17 mile run I didn’t have to adjust them once.
Sound quality isn’t as good as in-ear headphones but that’s like saying a convertible car doesn’t handle as well as a hard top, different tools for different jobs. The sound is a little ‘tinny’, it lacks base and mid, but it’s something you only notice before you leave the house. Let’s face it, running headphones don’t have to have the best sound, they need good sound, good battery, comfort and not isolate you from your surroundings. I have my Bose QC35s if I want to immerse myself.
You can hear everything that goes on around you, and the direction it’s coming from.
The buttons need a little work, the press needs a more affirmative click - it’s tricky to find the button and know if you clicked it (while waiting for the digital blip for confirmation), especially with running gloves.
Fix the buttons and improve the sound a little more, and these would absolutely perfect. Even with these areas for improvement - we’ll worth the £150.

Very much better than in-ear headphones for comfort, and not emitting as constant quiet hiss as some other bluetooth headphones do.
If you're lying down, the headband at the back gets in the way. No problem, just move it to the top of your head; the transducers work fine in different positions on your head.
Lack of a 'skip back' button control is rather a shame. I'd be using that far more often than skip forward, for instance when listening to podcasts after having paused due to an interruption. You need to skip back a bit just to get back into context.
Others have mentioned the transducers tickling. This only happens at high volumes, and almost never in my normal listening conditions.
They feel very well made and robust. Maybe spectacle frames could be made this way for durability and comfort, with a titanium alloy core coated with silicone rubber.
A limit of two devices maximum for pairing is rather low and something they might improve in future.
