Newly designed shape and material for a comfortable fit. It doesn’t feel like it’s being forced into your ear. It suppresses landing noise and wind noise, so you can concentrate and run without stress. Open-type ear pieces are also provided to let you hear ambient noise while running. Easy touch control while running maintains stable fitting unlike pushbutton operation. One-touch operation to reduce volume and take in ambient sounds. You can quickly have a conversation whenever you need. Touch control means there's no need to have a controller unit between the cable. Since there’s no controller to weigh down or pull on one side, you can concentrate on your running without distractions.
