Mic Windscreen Comparisons

Wind noise can really shatter the illusion of a field recording, so windscreens are a boring but essential part of every kit. I’ve been testing windscreen options for a few years, so I’ll park that knowledge here.

Goals

I’m primarily testing windscreens that are small, practical, and relatively inexpensive or DIY. I’m not interested in on-camera dialog, so concealment doesn’t matter. I just want something I can take out of my bag in a reasonable wind and get a great recording. Most of the items below are furry covers that fit over the foam that usually comes with a mic. They are known as windjammers, dead cats, dead kittens, etc.

A blimp is a larger cage that completely surrounds the microphone. They are much more expensive (and effective) than the options I list in this table. I don’t intend to test blimps here, but I’ll add them if I come across them.

Summary

  • Best Lav Windjammer
    Movo WS10m. A sleeper. It’s cheap and more effective than the expensive options from Rycote and Bubblebee.
  • Best Stereo Windjammer
    The Rycote windjammers in a variety of sizes are well-made and they perform great.
  • Best Budget Stereo Windjammer
    The Zoom WSU-1 works very well on a variety of recorders and stereo mics, and is cheaper than similar Rycote options.

DIY Note: If you are inclined, you can make windscreens that are more effective than the options above. All you need is fake fur, a sewing machine, and some time. See the table below for more info..

Name Size/Type Cost (each) HF Cut @ 10kHz + Wind Effectiveness
(Scale: 1-5)
Notes
Window Air Conditioner foam Raw Material 0.5 dB Very open foam, might be useful for interior of blimps?
Spandex Raw Material 0.7 dB Intended as outer layer for DIY blimps
Sports Mesh Raw Material 1 dB Intended as outer layer for DIY blimps
Foam Windscreen Raw Material 0.5 dB 1 A catch-all entry for the foam covers available for all microphones. Makes a good base layer for fur, but otherwise useless outdoors.
Rycote Windjammers (various) Stereo $40 – $100 3 dB 5 The practical “gold standard” for effectiveness and minimum attenuation. I’ve used several models and they are all good.
Auray WRW-H4N Stereo $35 7 dB + 4 B&H “house brand” windjammer intended for small Zoom recorders. Effective, but major HF cut. Avoid.
Zoom WSU-1 Stereo $30 2 dB 4 Long fur with inner lining. Great balance of effectiveness and HF response.
Zoom h1n: fits over foam.
Chromlives Wind Muff for Zoom H1 Stereo $13 8 dB + 2 Avoid! Insane HF roll-off and minimally effective.
Movo WS9 Stereo $15 3 Zoom h1n: fits over foam.
Bestshoot Deadcat Wind Shield for H1n Stereo $10 3 Zoom h1n: fits without foam.
Rycote Lavalier Windjammer Lav $23 3 dB 2 HF cut similar to larger Rycote windjammers, but effectiveness is worse than cheaper options.
Movo WS-RD10 Lav $5 5 dB Rubber insert to fit nicely on 10mm capsule, but weird midrange resonance and steep HF cut disqualifies it.
Movo WS-G10 Lav $5 5 dB (and steep cut above 10kHz) 2 2-piece set designed for specific mic, but sizes are useful for many others. HF cut disqualifies it, though.
Movo WS10m Lav $2 1 dB 4 (Sometimes listed as WS10n) Best commercial lav windmuff I’ve heard. Cheap, very effective and minimal HF cut.
Comica CVM-MF1 Lav $3.30 2 dB (but steep cut at 15 kHz) 2 (Comes in black or grey) Nice draw-string closure, but not very effective.
Bubblebee Windbubble (size 4) Lav $27 2 Under-performed relative to price, didn’t bother to test HF cut.
Zramo 6-10 mm Muff Lav $1 2 Ineffective, Didn’t bother to test HF cut.
DIY Lav (Alaskan Husky) Lav $ 1 (varies) 3 dB 5 Made with “Alaskan Husky” fur from Big Z Fabrics, which I found to be the best of several fake fur options. Larger, but more effective windjammer than any commercial options I tested.

Test Methodology

HF Cut

  • I used REW software to plot a sine sweep with a speaker and a 10mm omni mic capsule to determine how each windscreen alters the frequency response of the mic. The table shows the amount of high-frequency reduction around 10kHz, along with any notes about other frequency anomalies.

Effectiveness

  • For lavalier windjammers and raw materials, I set up a 10mm omni capsule at 0.5m from a fan running at a constant speed to produce 5-6 mph wind speed at the microphone. I made test recordings of each sample with matched gains, then compared the recordings subjectively to assess effectiveness. A rating of 5 means that I would happily record with that setup, and any wind noise would be minimal or nonexistent.
  • For stereo windjammers, I did a similar test with a Zoom H1n recorder. Note that the directional mics on the Zoom are naturally more wind-sensitive, so I haven’t found a windjammer that I would rate as a “5”. It really requires a larger “dead air” space like a blimp would provide.
