It's open-air design with air conduction technology, so that you can hear ambient sound while you are at outside. Let your ear breath all the time.
The lightweight(only 35g) and floable design (120 degree rotation) make RING headphones suitable for all head shapes,
which make sure they stay still securely on your head and never drop like TWS headphone.
Perfect choice for running, cycling ,driving etc.
Have been looking for a pair like this for running but can't find many reviews. Thinking of playing it safe and going with Aftershokz.
