What brand of earphone is it?

Quoted: I knew the ear tips are changeable but when I want to use the same type of ear tips, then do I need to change them from time to time? In addition, their colours do not match also. I think is quite impossible to exchange with other owner, so the brand not so important right? Back to the topic, regarding the warranty claim...

Can you rephrase it because I can't make out what're you trying to say here, sry.
