Purpose / Use: Designed for motorcycle/helmet use to reduce wind noise while riding, without overly muffling desirable sounds (traffic, horns, intercom, etc.).
Noise Reduction: They advertise −24 dB of wind noise reduction via the integrated precision filter.
Fit / Sizes: Supplied with two sizes (Medium and Large) to suit a better fit.
Materials & Design:
• Made from medical-grade thermoplastic elastomer (TPE), silicone-free and washable/reusable.
• Includes a precision filter; designed to allow conversation, sirens, and horns to come through while filtering out high wind noise.
• They come with a small hard case (or carry case) for protection and portability.
Intercom Compatibility: Specifically noted as “intercom friendly”—i.e., they don’t block or muffle the sound from helmet communication systems too much.
