EarPlanes prevent inflight ear pain caused by air pressure changes during air travel. Now, a free download of the EarPlanes+ smartphone app is also included! The EarPlanes+ app monitors real-time cabin pressure on your flight and sends notifications when EarPlanes are needed for ear protection. Use EarPlanes with the app for highly precise protection (the app will catch mid-flight pressure shifts), or just wear them during take-off and landing when air pressure is changing the most.
