Ear size, especially that of the ear canals, varies between individuals, so the earphones may not fit perfectly to your ears, which causes this issue. Please try the following solutions:

1. To ensure an optimal wearing experience, it is recommended that you clean the earphones on a weekly basis, in particular the mesh, charging port, metal contacts, ear tips, and parts that come into contact with your skin.
2. The left and right earphones are marked with "L" and "R" respectively. Please wear them correctly. Skip this step if you are using the WATCH Buds earphones.
3. Adjust how you wear your earphones or how deep the earphones are inside your ear canals to reduce the pressure.
    

   • FreeClip features an open-ear design and its acoustic ball does not need to be inserted into the ear canal.
   • If you are using FreeBuds Studio, pull out the sliders to a proper length until you feel comfortable when wearing the headband.
4. After every hour of wearing your earphones, take them off and gently massage your ears. Avoid picking your ears immediately after you have worn the earphones for a long period, to prevent any pain being caused.
    

   • If you feel uncomfortable when wearing FreeClip earphones, adjust the bean-shaped part to a horizontal position until you feel comfortable, or take them off and gently massage your ears.
   • Do not wear the earphones before falling asleep, to avoid any potential strain on your ears.
5. Avoid using the earphones to listen to music or audio at a very high volume (60% or higher), as this can cause damage to your hearing and result in ear discomfort.
6. If your earphones come with ear tips of different sizes, try another pair of smaller size (only applicable to earphones with ear tips, such as the FreeBuds Pro 3, WATCH Buds, FreeBuds Pro 2, FreeBuds 5i, FreeBuds SE, FreeBuds Pro, FreeBuds 4i, FreeBuds 3i, FreeLace, FreeLace Pro, and FreeLace Lite).
