These will be used with 2-way radio, so music quality is unimportant. Actually, rolled off bass & treble would act as noise filters, so might be better for voice. My other requirements are small size, excellent isolation, and can use common replacement tips. Even though low price is first, build quality is also a consideration. They will get plenty of abuse, so I'm looking at the annual cost (price X number of replacements).
