Combining the legendary sound of the 4088 Directional Capsule with the lightweight and DPA's flexible headset system, the 4288 CORE Directional Flex Headset Mic is ideal for both spoken word and vocal performance applications. This headset mic offers accurate and natural voice intelligibility and very high-SPL capabilities—users can both speak and sing into the mic with no hint of distortion.

This mic provides excellent off-axis rejection in high-SPL situations. It efficiently suppresses distant sound sources, making it perfect for demanding live performance environments where background noise and feedback are concerns. In high-SPL events, or when feedback is a concern, the 4088 Directional Capsule will tackle these challenges with ease. The bass response is designed for optimal linearity at 2-3 cm (1 in) from the sound source. This means that the bass roll-off will be relatively prominent at a greater distance—a paramount factor when it comes to rejection of background noise and in the fight to avoid feedback. The microphone capsule is also optimized for low distortion as well as humidity resistance.

The 4288 Headset Mic sits more securely around the head and is ideal for active performance situations. It’s ergonomically designed to fit comfortably and easily and can be adjusted to fit any ear size. At the same time, it mounts securely and is hardly visible. By rotating the boom and the earhook, the microphone can be easily used on either the left or the right ear. The connector splits the cable from the microphone boom allowing you to swap broken cables and/or wireless connectors quickly.

The directional boom length on this headset mic is 100 mm (3.9 in).

IP58 Certified
All CORE by DPA technology microphones are IP58 certified. This durability is achieved through several defense mechanisms:

• Water-repellant nano-coating of the cover and housing
• Hermetic sealing of the sensitive amplifier at the core of the mic
• Dual gold plating of the diaphragm
