There are 3 different INAIRS models: AIR1, AIR2 and AIR3. Each of them is compatible with a certain range of headphone models, depending on the size of the headphones’ nozzle. You can find an overview of the covered headphones and the corresponding INAIRS models here.

Each of our 3 INAIRS models (AIR1/AIR2/AIR3) is available in three different sizes: small, medium and large. The 3 different sizes are made to perfectly adapt to your individual ear canal. If you have a small auditory canal, you should choose the small size. If you have an auditory canal neither small nor large, you should go for the medium size. And if your auditory canal is quite big, please choose the large size.

If you can’t find the right INAIRS model for your headphones, please measure the diameter of your headphone’s nozzle. Then select the fitting AIR model:

• AIR1 covers a nozzle diameter ranging from 4.6 to 5.4 mm
• AIR2 covers a nozzle diameter ranging from 5.5 to 6.5 mm
• AIR3 covers a nozzle diameter ranging from 3.2 to 4.0 mm 

There are 3 different sizes available for each of our 3 INAIRS models: small, medium and large. 

• The small size has a width of 11.2 mm and a height of 10.7 mm
• The medium size has a width of 13.0 mm and a height of 10.7 mm
• The large size has a width of 14.0 mm and a height of 10.7 mm
  

First, press the top of the INAIRS tip together so that it forms an oval at the end. Then, push the compressed tip onto the nozzle at an angle of 45 degrees. Finally, gently push the tip over the whole nozzle. We also have a video tutorial showing this easy technique.
