They are way better then I thought. I thought I would have to sacrifice sound quality because of the design, but figured it was worth it to be able to hear traffic while running. While I can still hear just fine, the music also sounds great and clear!

After a few months of use, I can now give a review of this strange product. Following the default of how many others do when they make an assessment, so plus and minus follow below. Plus: - Connects quickly to bluetooth and keeps the connection good.

The main issue is when wearing a jacket, the headphones get pulled around behind the neck and makes it uncomfortable and difficult to look behind. This is really bad when you need to look around often through the city. Also not great with a helmet, but it's acceptable.

The AfterShokz Trekz Air is a very likable sports headphone, particularly for people who want a secure fitting headphone that doesn't cover or prod their ears.

The AfterShokz Trekz Air is a slimmed down bone-conduction headphone that offers improved sound and is very comfortable to wear, leaving your ears open to hear the outside world; It works well as a headset for making cell-phone call and comes with a nice carrying pouch

While the sound quality is improved; it's still not as good as what you'd get from a comparably priced "traditional" headphone

Weathering both salty sweat and the daily gym-bag battering, Trekz Titaniums are perfect for fitness.

Fast recharge time; Quick; easy equalizer; Great volume range; Sweat-proof fit; Tough construction

Tight on larger heads; Difficult to wear with gear; No previous track command

Do you exercise or commute in magnificent isolation? Blocking-out ambient noise is the best way to immerse yourself in your music. If you're working out in a gym then that's all fine, but if you're out on a run in an urban environment, or commuting through busy streets and stations, you do actually...

Exacting design; Comfortable & stable fit; Flexible & lightweight; Helps situational awareness

Low volume; Ear 'tickle; Sound quality is lacking; Short battery life

I would like to start my conclusion on a positive note by recommending for whom the Aftershokz Trekz Air are suitable. These are users who want to make hands- and ear-free calls during sports, in the office or on the beach.

Cycling while wearing headphones isn't advised. Yet everyday, in the city especially, chances are you'll encounter at least a few cyclists wearing either in-ears or over-ear cans in place of a helmet. Road safety be damned.

Bone conduction works well; Great level of situational awareness; Reasonable battery life

Slightly uncomfortable after prolonged used; Sound leakage; Lacklustre sound quality

Aftershokz' unique bone conduction design has the huge advantage of not covering your ears. The speaker element sits in front of your ear, on your cheekbone, and vibrations generated by the sealed units conduct the sound.

Long runtime; clear sound; quality construction

High price; overwhelmed by wind noise at higher speeds
