6061 CORE Subminiature Lavalier Microphones are just 3 mm (0.12 in) in size but pack the audio power of our larger,  award-winning DPA mics. What they lack in size, they more than make up for in clarity, consistency and durability – three qualities that really matter. By shrinking CORE by DPA technology, we ensure you don't have to compromise on sound to focus on aesthetics.
