ETY•Kids3 (ek3) headset + earphones

The eartip that is most comfortable is the likely choice, but it MUST SEAL well in your ear. If you can easily hear others when the volume is off, you don’t have a good seal. Twist it in deeper, or choose another eartip.
When changing eartips make sure the eartip fits securely on the stem of the earphone.
Important: Sound quality, full bass response and noise isolation all depend on a good eartip seal in the ear canal.
Care
Over time eartips may lose their elasticity. For best performance and retention, replace 3-flange eartips every 3-6 months. Replace foam and glider eartips regularly.
