The Hollyland 3.5mm Air-Duct Earphone (Model: HL-ADE01) is a specialized, discrete replacement headset designed for the beltpacks of the Syscom 1000T and Mars T1000 full-duplex wireless intercom systems.

Unlike traditional over-ear production headsets that can be bulky and hot during long shoots, the air-duct earphone relies on security-style acoustic tube technology. This form factor delivers a professional, low-profile look that is perfect for directors, floor managers, and security staff who need to stay connected without drawing attention on camera.

Core Technical Features

  • Acoustic Air-Duct Isolation: The earphone features a clear, hollow acoustic tube that uses air to transmit sound waves from the driver housing up to your ear canal. Because there are no live electrical wires leading directly into your ear, it prevents electromagnetic interference and delivers a clean signal.

  • TRRS 3.5mm Connection: Built with a standard 4-conductor (TRRS) 3.5mm plug. It transmits incoming team audio and handles your outward microphone feed simultaneously through a single, solid connection point.

  • In-Line Capsule Microphone: Features a compact inline microphone unit housing a sensitive voice-frequency condenser capsule. It ensures vocal responses are localized and easily heard over the main intercom channel.

  • Ergonomic Comfort: The soft, silicone earbud tip is engineered for comfortable all-day use. It seals comfortably in the ear canal to offer passive isolation, helping you hear crew communications clearly over ambient stadium, concert, or studio noise.

Physical Dimensions & Layout

  • Total Upper Length: 45 cm from the primary speaker driver housing to the silicone earplug tip (plenty of slack for routing cleanly behind the neck or pinning to a shirt collar).

  • Total Lower Length: 95 cm from the 3.5mm audio jack up to the main driver housing.

  • Chassis Accent: Space Gray/Black cabling with a completely transparent, high-grade plastic air duct section for low visibility.

Operational Maintenance Tip: If your crew reports that team comms sound muffled or unusually quiet on this specific headset, check the clear acoustic tube before replacing the whole unit. Over weeks of live event use, moisture from sweat or standard earwax can easily build up inside the tiny air canal, blocking sound waves. You can quickly snap the clear tube section off the speaker housing, flush it with warm water or a blast of compressed air, let it dry completely, and pop it back on to restore full, crisp audio quality.

Great value: These are my go-to work from home shirt
Material Type: Recycled Polyester, Color: Blue, Size: X-Large
I’ve been pleasantly surprised by these shirts and wear them weekly for Zoom calls, since I’m still working from home these days. I figured at the price point it was worth trying them out, and now I’ve bought several in different colors. They aren’t super soft, but they are comfy and look nice. I’m 6’1” ~220 pounds, and the XL slim fit still has plenty of room. I imagine the regular cut is incredibly boxy and oversized. The difference between polyester vs recycled polyester is inconsequential. I typically buy expensive golf shirts, and these definitely aren’t as nice. They are a fraction of the cost though and a great “beater” work shirt / hang out shirt. It’s nice wearing something that looks and feels decent, but if something happens to it, you can toss and it and pick up another for the cost of a chipotle burrito.

Great price, not great quality
Material Type: Recycled Polyester, Color: Black, Size: Small
Simple, straight forward all black polo. I am a size medium woman (with some room since I don't like form-fitting) and bought a men's small. Fits perfectly for my frame. Long enough to tuck in for my part-time extra weekend job uniform. Also suitable for the golf course. A little thin, and if you hold it up to light you can sort of see through it. *Not* flowy, soft and smooth fabric like a rash guard/sun shirt - more structured than that. But it's cool and does the job for the price under $10.
