Microphone Pop Filter Mozos PS-4 — foam ball windscreen for vocal and instrument mics

Mozos PS-4 is a foam ball windscreen designed to fit over handheld and small studio microphones. The foam pop filter reduces plosive sounds and wind noise, protects the microphone capsule from saliva and dust, and helps maintain consistent vocal clarity during recordings and live performances. The compact shape and elastic inner opening allow the windscreen to be mounted quickly on most handheld and short-bodied shotgun or instrument microphones where basic wind protection and pop reduction are required.

Advantages

The Mozos PS-4 foam windscreen provides effective reduction of plosives and breath noise without significantly altering the microphone’s tonal balance. Its closed-cell foam construction resists moisture and dust while remaining lightweight and durable for repeated use. The elastic mounting fit accommodates a range of microphone diameters and holds the windscreen in place during performances. The simple design requires no tools and is compatible with common vocal, reporting and instrument miking scenarios.

Suitable for

• Vocalists using handheld microphones in live or studio settings
• Podcasters and presenters seeking reduced plosive noise
• Field reporters and interviewers needing quick wind protection
• Instrument miking where a compact windscreen is preferred (acoustic guitar, brass, woodwind close miking)

Key specifications

• Material: closed-cell acoustic foam
• Shape: spherical foam windscreen (ball)
• Intended use: handheld and short studio microphones
• Functions: plosive reduction, wind noise attenuation, capsule protection from moisture and dust
• Mounting: elastic inner opening for push-on fit
• Weight: lightweight for minimal handling noise impact

How to use

Stretch the elastic opening of the Mozos PS-4 and push it evenly over the microphone head until it sits snugly against the grille. Ensure the foam covers the capsule completely and that the windscreen does not obstruct any switches or connectors. For best results, position the microphone at the typical performance distance for your application and check sound levels before recording or broadcasting. Clean the windscreen by removing it from the microphone and wiping with a damp cloth; allow it to air dry fully before remounting.

Usage recommendations

For critical studio vocal work where maximum high-frequency detail must be preserved, test the PS-4 on your microphone and adjust placement to find the balance between plosive reduction and tonal transparency. Replace the windscreen if foam becomes torn or permanently compressed to maintain protection and acoustic performance.
