If you have problems with ear clearing during flights (pain or strong pressure on your ear during start and landing) we have something special for you: earPlanes.
A new development against air pressure in planes is N300.
If you want to dampen the noise in the aircraft but still lead a conversation you should choose a plug with best sound qualities: MusicSafe SonicSet Pro.
New and already very successful: Jazz.
Jazz protects very well and comes with a freaky design.
