The new Enttex N300 – finally a solution to reduce the pain of blocked ears. Until now, there has not been a drug-free and convenient solution to provide relief for blocked ears associated with flying in an aircraft and scuba diving. Renowned ears, nose and throat (ENT) surgeon, Associate Professor Burkhard

Franz (M.D., D.AUD., M.MED.) developed the N300 after finding there was nothing else on the market that gave relief to his patients who suffered with blocked ears.

How do you use it? Simply place the ear tip of the N300 negative pressure to assist with equalizing. It can be used at the first sign of discomfort and used time and time again, unlike other products which are disposable and must be left in the ear for the duration of the flight — try that for 15 hours! The safety valve limits the pressure one can apply so no matter how hard you pump the diaphragm, it will always stay at a safe level for the ear drum.
