Specs
Pros
Pro Will not compromise your awareness of your surroundings
These headphones do not have to cover your ears for you to hear music, thanks to its bone conduction technology. You will still be able to hear your surroundings which should help maintain/improve awareness and safety when running or working out outdoors.
Cons
Con Can cause a potentially uncomfortable tingling sensation on your head
Some experience a tingling sensation on their head, especially when listening at higher volumes. This can be attributed to the bone conduction tech, which uses the bone structure of the face for the sound waves to travel through.
Con May sound dull or flat to some
The sound that these headphones produce will not wow anyone. Bass is present but sounds quite loose while the mids and highs sound thin. With these, sound quality is compromised in favor of portability, convenience and added awareness of your surroundings.
