Product Description

The HearDefenders®  Digital Basic Multi-Memory (HDWDB2MM) electronic earplugs are our mid level 2 channel units with multi-memory within our custom-fit waterproof electronic hearing protection series.

The HearDefenders® HDWDB2MM distinguish themselves as one of the most affordable mid-range custom-fit electronic hearing protection/enhancement system in the marketplace.  They feature a faster processor and better digital circuitry over our HearDefender® WDS model that brings out better clarity to game calls and vocal tones, with improved feedback reduction.  They will also have an adjustable volume control and passive protection of /- 24-26NRR.  Both are P2i Aridion Nano-Coated for water repellency and ideal for foul weather conditions.

Much like all of our waterproof models, the HearDefenders® Custom Series is available in multiple faceplate colors and shell combinations.  It comes professionally packaged with batteries, cleaning tools, and care and user instructions for long-term enjoyment. If you’re looking for something affordable, digital, easy to use and custom-fit for your ears, the HearDefenders® HDWDB2MM is an excellent choice!

What is a Multi-Memory function?

Originally developed for the waterfowl community, this multi-memory feature becomes very valuable to those users who are constantly surrounded by wind and miscellaneous background sounds. With a simple push button on the faceplate, the user can go from a normal enhancement/protection mode to a further suppressed background sound mode before recycling it back to the original position.

Multi-Memory units have become a favorite for waterfowl and upland bird hunting, as well as those who wish to carve out unwanted “distraction” noise without losing complete contact with their environment.

The Multi-Memory feature goes through 3 functions:

  • Full Spectrum
  • Background Noise Reduction
  • Mute


  • Without Multi-Memory
  • Available in Full Shell model only
  • 2 Channel, 12 Band Clarity
  • 100% Digital Instrument
