The Audéo PFE comes with both silicone and Comply™ foam tips; the silicone tips are washable and better for use during exercise. The Comply™ foam tips are better at filtering out ambient noise, making them the best choice for travel or use in noisy surroundings.
To change the ear tips (foam or silicone), grab the tip in the middle and pull it slowly until it comes loose. Do not use your fingernails or any other sharp object to remove the ear tips, as they could be damaged.
