Five pairs of tips are included when you originally buy the ER-4 earphones. These are replacement tips. These tips fit many other earphones, too! This pack contains 5 pairs of AVERAGE size black foam tips.
5 stars for this seller! (4 stars for the tips themselves: they degrade too fast, but when new they still provide better noise attenuation than any competitor - Comply’s Pro series tips are 2nd best choice.)
best-in-class sound attenuation
frustratingly short life before performance degrades
