Guided tours run on clear, uninterrupted communication between a
leader and the group. The YingMi 008S delivers that with
full-duplex 2.4G transmission, ENC noise reduction, and a headset
built to be worn all day.

Core Features
Two-Way, Not Just Broadcast
Most guiding intercoms only push audio one way — a leader talks,
the group listens. The 008S is full-duplex: while the host
broadcasts to the whole group, any member can request a call and
speak back once approved. That matters when a visitor needs to ask
a question mid-tour, or a guide needs to check in with someone
who's fallen behind.
Clear Audio in Real Conditions
ENC dual-microphone noise reduction keeps conversation intelligible
in the environments guided tours actually happen in — busy
exhibition floors, outdoor sites, factory walkthroughs — holding
system distortion under 1% even with input up to 110dB SPL.
Stable at 100m, Low Latency
The 2.4G band gives strong interference resistance across an
open-field range of up to 100 meters, with end-to-end latency as
low as 20ms so speech stays in sync.
Multiple Groups, No Crosstalk
Each host pairs to its own sub-units through a manual button step,
then locks that channel so outside signals can't interrupt it —
letting several tour groups run independently in the same venue.
Product Details
The 008S ships as a host unit (guide) and one or more sub-units
(group members), both built as the same all-in-one headset —
earcup, microphone, and controls molded into one piece, no external
wiring. Power on and each unit auto-connects to its paired
counterpart.
| Control | Host | Sub-Unit |
|---|
| Power | Long press 3 sec to toggle on/off and auto-reconnect |
| Volume | Short/long press, 6-level cycle |
| Pairing | Long press together with the counterpart unit to pair |
| Call | Double press to accept a call request | Double press to send a call request |
| Extra | Short press locks the channel to block outside interference | — |
| Type-C | Charging/firmware (5V/0.5A); auto shutdown after 10 min idle |
Battery is rated for roughly 10 hours of continuous use per charge,
spanning a full day of back-to-back tours, with a Type-C charge
taking about 2.5 hours.
Application Scenarios
Museum and exhibition tours, factory and corporate visitor
reception, scenic-area study tours, engineering-site coordination,
and outdoor training all share the same need: a leader who can talk
to everyone, and a way for anyone to talk back. The 008S is built
around that pattern rather than one-way-only broadcasting.
FAQ
1.Is this a one-way broadcast system or two-way?
Two-way. The host broadcasts to the group, and any sub-unit can
request a call; once approved, both sides speak.
2.How many people can one host support?
The system runs on a one-host-to-many-sub-units architecture, with
each sub-unit individually paired and channel-locked to its host.
3.Will it stay clear in noisy environments?
ENC dual-mic noise reduction keeps system distortion under 1% and
supports input up to 110dB SPL, which covers most outdoor and
industrial noise levels.
4.Can two tour groups run in the same building without crosstalk?
Yes. Each group pairs and channel-locks independently, so separate
tours don't interfere with each other.
5.How long does a charge last?
Around 10 hours of continuous use from a full charge, with charging
itself taking about 2.5 hours over Type-C.
