Need help choosing?

Choose the DPA 4166 if you need a discreet single-ear earset for stage, speech, broadcast or location recording. Select the colour to blend with skin or wardrobe, then choose the shorter 90mm or longer 110mm boom for your positioning needs. The 90mm option is MicroLock only; 110mm is offered with MicroLock, 3-pin LEMO, TA4F Mini-XLR or 3.5mm Mini-Jack. MicroLock with an appropriate DPA adapter is the most flexible choice for switching wireless systems. For a dual-ear headset, look for the DPA 4266 instead.

Important Notes

• This listing is for the DPA 4166 single-ear Flex earset microphone, not the 4266 dual-ear headset.
• All 15 variants use CORE+ by DPA; this is not the older legacy CORE specification.
• The 90mm boom is only listed with MicroLock; the 110mm boom offers all four termination options.
• MicroLock connects to MicroDot accessories, but its click-lock protection works only when both connector halves are MicroLock.
• Confirm the selected termination is correct for your wireless transmitter.
• DPA specifies a 2-year manufacturer warranty.
