Sennheiser MZC 1-2 GOLD Large Frequency Cap

The Sennheiser MZC 1-2 GOLD (Article Number: 509492) is a factory-original original equipment manufacturer (OEM) acoustic modification accessory designed for professional subminiature condenser microphones, specifically the Sennheiser SL Headmic 1 series and MKE 1 lavalier microphones.

When dealing with theater actors, corporate presenters, or broadcast speakers, vocal clarity can occasionally be masked by thick clothing, heavy costume materials, or a performer's physical posture. This specialized slip-on gold-plated cap changes the acoustic physics at the diaphragm inlet, physically boosting upper-mid and high frequencies to maintain pristine speech intelligibility without digital equalization.

Key Architectural and Acoustic Attributes

  • Passive High-Frequency Presence Treble Boost: Sweeping from the upper-midrange into high frequencies, the large cap physically contours air currents entering the capsule chamber. This accentuates presence, adding a clean treble lift that helps speech cut through dense musical mixes or large live public address (PA) venue reflections.

  • Premium Gold-Plated Aesthetic: Finished in a polished, low-friction gold plating, this cap complements matching gold-chassis headset variants. It delivers an elegant, high-end presentation look for broadcast hosts, musical theater leads, and executive keynotes.

  • Integrated Secondary Moisture Deflector: Beyond acoustic tailoring, the cap functions as a mechanical shield over the subminiature capsule ports. Its precise micro-grille alignment deflects stray moisture, sweat, and hairspray away from the internal pre-polarized condenser elements, preserving the lifespan of the mic.

  • Built-in Wind Shielding: The geometric design provides structural protection against direct air movement, cutting down sudden low-level breath pops or drafts by roughly 15 dB without needing a bulky foam windscreen.

Field Configuration and Application Advice

When to Deploy the Large Cap: Choose this Large variant (1-2) if your microphone is hidden inside a performer's hairline, taped under heavy wardrobe fabric, or if the speaker has a naturally deep, dark vocal timbre that lacks definition. If the microphone is positioned close to the mouth and only needs a minor presence lift, consider using the smaller MZC 1-1 variant instead.

Tool-Free Slide Installation: Installing or swapping a frequency cap requires no special tools. Gently slide the cap directly over the tip of the subminiature microphone capsule until it locks firmly into place over the friction collar. To ensure consistent audio performance and prevent buildup, periodically remove the cap and wipe it down with a dry, lint-free cloth to clear away skin oils, sweat, or stage makeup.

Hard to put on but easy to come off
Size: 12-18 Months Toddler, Color: Sebastian Shark Blue
As the title says, the shoes were a bit hard to put on and perhaps that was because we were doing it for the first time . However, they would come off super easily and so we lost one of the shoes the second time the baby wore them. That was a bummer as they aren't particularly inexpensive. We didn't really get to try them out as much as we'd have liked but based on what we saw, they looked comfortable and durable. Baby loved the shark design.

Held up for well for 5 months. Fit my son’s chubby feet like no other shoe.
My son has been wearing this shoe since he was 9 months old and was cruising furniture. I bought the 6-12 month size. He started walking at 10 months and is 14 months now. He’s still wearing this shoe and it has held up well. I have him barefoot in the house and mostly use it for when he’s in the back yard, at the gym childcare and when we are out and about. He wears shoes for several hours a day at least, though I bought the Robeez sandals at the start of summer and have been switching between the two pairs. My son has wide feet and doesn’t really fit in anything but soft sole shoes. His feet are about 5” long now and these shoes are getting too small. It’s almost time to size up! They’ve treated us well. Plus they are super cute and match every outfit. He giggles when I put them on.

Cute, different, and good quality
I had these for my kids when they were little. I am now buying them for my first grandchild. They appear to be the same good quality they were years ago. I highly recommend : )

Great shoes for the little one taking his/her first steps
Great shoes for the little one taking his/her first steps!! I actually ordered 2 pairs, one for my son in the 12-18 months (even tho he was 10 months old) and a 6-12 month for a friend. The 6-12 month fit my son perfect!! (my son was in a size 5) but I knew they would only last a few weeks so I kept the 12-18 month ones and he started wearing them. He seemed to like them, never tried taking them off and they were easier to walk in than socks but for some reason the top of the foot area is HUGE! They stayed on no problem but lots of wiggle room in the top... He is now running and wears shoes with a thicker sole for the rocks but we still love these for inside when it is too cold to go barefoot. I would say the 12-18 month fit like an average size 6.
