In my never-ending search for headphones that are comfortable and I can use while walking along the roadside in the morning I brought a pair of AfterShokz Sportz M2. What makes AfterShokz different then most other headphones is that it uses bone conduction to work. Instead of placing the earpiece in your ear, it lays in front of your ear along your jawbone. The sound is then conducted through the bone into the inner ear.
I wore it yesterday morning while walking two miles in hot and humid weather and it was quite comfortable. Once I figured out where to set them to get the best sound they stayed there, despite my sweating. While on the walk I listen to some music and a bit of a podcast. The podcast came through well, I could hear it clearly even when a car went by. The music was fine, the bass was a little weak but not bad. The volume control and on off switch is on a small box on the cable which you can clip on to your shirt. The model I brought also has a switch to answer phone calls. I don’t make or receive a lot of phone calls so haven’t been able to test that yet.
Overall I am happy with the AfterShokz Sportz M2. They were comfortable, stayed put even while sweating and the audio was fine. However they are not perfect, as I said before although the audio was fine the bass was weak. So if you like bass thumping music, these are probably not the headphones for you. Also if you wear glasses these are not the headphones for you. I tried to wear my glasses and it didn’t work, I couldn’t get the headphones to lay correctly. If you are not an audiophile, don’t wear glasses and are interested in headphones that use bone conductivity I would take a look at the AfterShokz M2.
