Hyper-realistic sex doll design has made great strides over the years. As the technologies that underpin these dolls have advanced, they become even more lifelike. The newest advancement in Irontech Doll’s Realistic Oral Structure (ROS) technology is ROS MAX. ROS MAX builds upon the already impressive ROS system to take facial expressiveness, anatomical detail, and overall user comfort to the next level.

What is ROS MAX?

ROS MAX (Realistic Oral Structure MAX) is the next step in Irontech Doll’s facial engineering process. With ROS, users gained highly customizable mouths that could move realistically and give impressive oral play. With ROS MAX, it’s as if Irontech Doll took the head back to the proverbial drawing board and reworked the entire inner and outer structure.

The original ROS upgrade came with an anatomically accurate oral canal, embedded jaw joint, and built in tongue and teeth, and ROS MAX takes each of these aspects to the next level, plus more! After reengineering the heads to add a high degree of expressiveness and further anatomical accuracy, functionality was next on the list of areas to see refinement. The internal structure of the eye socket has been overhauled for greater durability and realism while ROS MAX’s oral coloring is hyper-realistic and the mouth can be opened at various widths.

Core Features of ROS MAX

🔍 More Realistic Facial Details

  • Visible porcelain-like teeth, tongue, and tonsils
  • Slightly parted lips to show teeth naturally, mimicking human breathing
  • A subtle tongue-out expression for sensual realism
  • Teeth aligned perfectly with the lips, no awkward spacing or visibility

👁️ Movable Lower Eyelids

  • A newly engineered eye socket structure allows the lower eyelids to move independently
  • Maintains natural eye position even when the mouth opens. No more facial distortion
  • Enables soft expressions, blinking-like effects, and enhanced realism
  • Note: Users should wear gloves and use fingertips when adjusting eyelids to avoid makeup or silicone damage.

🦵 Upgraded Chin & Jaw Design

  • Improved jaw joint hardware makes articulation smoother and more durable
  • New placement allows for graceful, precise mouth movement
  • Chin now responds with light pressure and mimics real jaw support

⚖️ Reduced Head Weight

  • 500g+ weight reduction from the previous ROS design
  • Internal framework redesigned with a drop-proof tank and more stable base
  • Easier to handle, safer during play, and more comfortable on doll neck joints

🔮 Hyper-Realistic Oral Detailing

  • Carefully painted inner mouth with lifelike coloration
  • Teeth crafted to look like glossy porcelain—not plastic or flat
  • Combined with subtle tongue mobility for maximum oral realism

🤤 Orgasm Face

  • Adjustable eyelids allow for orgasm expression
  • More realistic experience

Optional Add-Ons Available

ROS MAX heads also support:

These add-ons elevate the sensory experience even further, making the oral interaction as close to human as current tech allows.
