BK SERIES
BK Series speakers provide broadband performance at value pricing. They are commonly
used for full range in-ear speakers and communications utilizing an earplug design.
CM SERIES
The CM Series delivers the benefits of balanced armature technology in a compact finished
package. The CM is ideal for use in situations where a non-contacting headset is required,
but signal voltage is limited – as is common for radios and wireless telephones. The CM
also conserves battery power, and provides static shock protection for the user.
