I have only used these for listening and haven't used them since. These are canal-type earphones with a clear design. The manufacturer is unknown, but they are canal-type monitor earphones, so they are stable. Due to the many unknowns, I will be selling them at a low price. If you are not particularly concerned about the brand and are looking for canal-type monitor earphones with a clear design, please consider them. - Type: Canal type - Color: Clear - Accessories: Large and small ear tips (different sizes) - Cable type: Detachable Thank you for viewing.
