The capsule of the d:fineÂ™ CORE 6066 Subminiature Headset is just 3 mm (0.12 in) in diameter, but packs the audio power of larger, award-winning DPA mics. Despite its small size, it is abundant in clarity, consistency and durability - three qualities that truly matter. By shrinking our newly introduced CORE by DPA technology, we ensure you don't have to compromise on sound to focus on aesthetics. Beyond this minimized size and maximized sound potential, these mics also sport a completely redesigned, lightweight, one-size-fits-all headset that attaches over the ears for maximum comfort. 3-point ear grips with spring mechanisms help grip below the ears and to the side of the head for added security. A 2-way adjustable boom system (length and height) with an anti-rotate mechanism makes this new headset very easy to fit. A new 90Â° cable management system safeguards the cable and directs it down the wearerÂ’s back, where it canÂ’t be seen. The CORE Subminiatures, are IP58 certified.
