About DPA Microphones d:fine CORE 4288 Directional Earset Mic, MicroDot, 100mm, Black

An exceptional fusion of superior sound quality and ergonomic design, the d:fine CORE 4288 Round Directional Flex One-Ear Earset Microphone with MicroDot Connector and 100mm Boom in sleek black, is a versatile audio solution for both spoken word and vocal performance applications.

This high-performance microphone integrates the renowned sound quality of the 4088 Directional Capsule with the lightweight and flexible d:fine Earset system. It delivers accurate and natural voice intelligibility, coupled with high-SPL capabilities, ensuring distortion-free sound even when users speak or sing directly into the mic.

Designed to excel in high-SPL situations, this microphone offers excellent off-axis rejection, efficiently suppressing distant sound sources. This makes it an ideal choice for demanding live performance environments where background noise and feedback are potential challenges.

The d:fine CORE 4288 microphone is resistant to humidity and features a flexible adapter system, making it compatible with most professional wireless systems. Its minimal visual impact and easy mounting to either the left or right ear make it a convenient and unobtrusive audio solution.

The microphone capsule is optimized for low distortion and humidity resistance, ensuring consistent performance in various conditions. The bass response is designed for optimal linearity at 2-3 cm from the sound source, providing a prominent bass roll-off at greater distances, crucial for rejection of background noise and feedback avoidance.

Available as an earset or headset, the d:fine 4288 caters to different user preferences. The earset variant is quick to put on, making it suitable for fast-paced settings like conferences, while the headset variant offers secure fit, ideal for active performance situations. Both variants are ergonomically designed to fit any ear size and head shape comfortably and securely.

The microphone features a connector that splits the cable from the microphone boom, allowing for quick replacement of broken cables or wireless connectors. It comes with two directional boom lengths to accommodate different applications and head sizes. The 100mm boom is designed for placement at the corner of the mouth, helping to avoid "popping" sounds.

The d:fine CORE 4288 Directional Earset is equipped with CORE by DPA technology, offering a 14 dB increase in dynamic range and delivering an even more open and clear sound. All CORE by DPA microphones are IP58 certified, ensuring durability through water-repellant nano-coating, hermetic sealing of the sensitive amplifier, and dual gold plating of the diaphragm.

The microphone's cardioid or directional pattern offers the most sensitivity at the front and least sensitivity from the sides and back, making it ideal for capturing focused sound on a busy stage. The unique DPA capsule technique reduces the sensitivity to sounds from the sides or rear without colorizing the sound, offering perfect sound stages.

The d:fine CORE 4288 microphone's adapter system offers flexibility and affordability. It allows you to switch adapters instead of purchasing a new microphone when changing wireless systems, ensuring sound quality remains consistent. Compatible with all leading wireless mic solutions, this microphone is a sound investment for years to come.
