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.

Good quality pillows
Color: White, Size: Queen Size Set of 2
These are very soft and supportive as advertised. W find them a little too thick for my taste (why I only gave 4 stars), but personal preference is very subjective with pillows. They are well made and high quality, and am happy with my purchase.

Overall, not that comfortable!
Color: White, Size: Queen Size Set of 2
Only okay. I find these pillows to be heavy, and not very conforming. Overall, not that great.

goose down pillows.
Color: White, Size: King Size Set of 2
Since receiving them, these king-size white goose down pillows have truly transformed my sleep. They are incredibly soft and fluffy to the touch, so plush it's hard to believe they hold their shape. Sleeping on them is like lying on a cloud. The 100% cotton cover adds extra comfort: it feels cool to the touch, breathes well throughout the night, and helps me maintain a comfortable temperature while I sleep. Furthermore, the "reinforced fiber" structure is noticeable: after several weeks of use, the pillows retain their support; they don't clump or lose their shape, ensuring consistently good rest. I find they have the ideal balance between firmness and softness: firm enough to support my neck and head, yet plush enough to adapt to my posture without creating pressure. This has improved my nights; I sleep more soundly and wake up with less stiffness in my neck. In short: these pillows combine luxury, comfort, and durability. If you're looking to improve your sleep quality with soft, firm, and breathable pillows—especially in king size—these are perfect. Definitely one of the best investments you can make for better sleep.

Hotel-like comfort at home I bought these pillows from Beautyrest and they really exceeded my expectations. They are very soft but at the same time have good support, which helps you rest better throughout the night. They feel like luxury hotel pillows, especially because of their down-like filling. The jumbo size is perfect and they come well filled, they are not easily crushed. In addition, the cotton cover feels fresh and of good quality. They arrived quickly and well packed. After using them for several days, they maintain their shape and comfort. I definitely recommend them if you are looking to improve your rest without spending too much.
