Ear tips are not universal and these will only fit on earphones that have a connection stem that is no larger than 3.5mm (the same diameter as the male earphone plug on wired earphones).
The listed brands use this connection diameter, but not every model made by these companies will use this connection diameter so PLEASE MEASURE prior to purchase, or ask us (tell us your specific model) and we will verify them for you:
