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.)
Pros
best-in-class sound attenuation
Cons
frustratingly short life before performance degrades
