Start with the lesound microphone factory walkthrough clip if you want the short version, and come back when you want the reasoning. A clip shows what the line looks like. It doesn’t show why each station is arranged the way it’s, and that reasoning is where most of the risk in a first order actually sits.
We shoot this footage on a working day rather than in a showroom, because a showroom can be arranged for a camera in an afternoon and a production line can’t.
Why a filmed walkthrough beats a catalogue page
A buyer choosing a microphone supplier is really choosing a set of hands. Two factories can work from a similar parts list and still turn out different products, because the difference lives in how carefully the hands treat a capsule, how many units get listened to before packing, and what happens to a body that comes out of the mould with a mark on it.
None of that fits into a spec table. A short film of the actual bench tells you more than a page of numbers, because you can see whether the person on the bench is working at a pace that leaves room for inspection or a pace that leaves none.
Ask any supplier to film a stage of production for you before you place a trial order. A supplier who can is usually a supplier who’s proud of the stage. A supplier who can’t is answering the question in a different way.
Station one, where the capsule goes together
This is the station that decides how the microphone sounds and the hardest one to capture in a photograph. A capsule is a diaphragm held under tension in front of a backplate, and that tension is set by hand at a bench rather than stamped onto a card by a machine.
What a buyer should ask to see here isn’t the parts but the check. Ask how a finished capsule is measured before it moves on, and ask what happens to one that measures outside the window. A factory that keeps everything has no window, and a factory that has a window and a scrap bin has a process.
Ask how capsules are stored between this bench and the next one as well. A capsule left open on a dusty bench is a capsule that gets blamed for a noise three months later, long after anybody remembers where it sat.
Station two, the grille and the metal that has to sit true
The grille is the part the customer touches and the part the camera sees, and it’s also the part that has to clear the capsule without ever touching it. Ask how the mesh is formed, because a grille pressed into shape too quickly springs back and a grille resting on the capsule is a microphone that has already failed.
Ask about the finish here rather than at the end of the line. A plating or a coating applied before assembly can be inspected while the part is still loose on the tray, and a fault caught at this point is a part that never enters a finished unit.
This is also where a buyer’s own logo normally lands. Raise it early, because a laser mark and a printed mark need different preparation, and the answer changes the lead time rather than the price.
Station three, the body and the wire inside it
Inside the body there’s a small amount of wiring, and small amounts of wiring are where intermittent faults live. Ask how the joints are made and how they’re checked, because a joint that passes a tug test today can fail after a season of being plugged and unplugged.
Ask what the switch bodies are if the model carries switches, and ask what happens when a switch wears out. A microphone that can be opened and serviced is one that stays in the customer’s rack, and a sealed body is a body that gets replaced.
Ask how the thread on the body is cut, because that thread holds the whole microphone on the stand. It’s a small part of the product and it produces the loudest complaint of any part when it strips.
Station four, the bench listen
Every unit gets listened to before it goes into a carton, and buyers find this the most interesting station because it’s the one a nice render can’t fake. Ask what the person on the bench listens for, and ask whether they listen alone or against a reference unit.
A bench with a reference unit on it tells you the listening is real, because the only reason to keep a known-good microphone beside you is to compare against it. Ask how often the reference is changed and what happens to a unit that fails the listen.
Ask whether the listen happens before or after the body is closed. A listen on an open body catches a wiring fault and a listen on a closed one catches everything else, and the two stations answer different questions.
What a buyer should ask to have filmed
If you can’t visit, the next best thing is a short clip of the one stage you’re worried about. Here is the list we’re asked for most often, and every item on it’s a reasonable request to make of any supplier.
- The capsule bench, including whatever the check looks like.
- A finished unit being listened to against a reference.
- The thread being cut on a body.
- The packing bench, with the accessories going into the box.
Ask for the clip dated and unstaged. Two minutes filmed on a phone during a normal shift tells you more than a produced video with music over it.
The sample, and how an order really starts
Almost nobody who visits a line orders a container on the spot. They order one unit, take it home, put it in front of the microphone their own customers use, and come back when they’re satisfied. That’s the sequence we plan for, which makes the sample the most important order we ship.
Ask what the sample includes. A bare microphone answers a question about sound and leaves the mounting question open, and the mounting question is the one that turns into a return. Ask for the sample with the mount and the screen that belong to it, so the customer tests a position rather than a part.
Ask how the batch is documented once the sample is approved. Photos of the actual batch rather than of last year’s sample, plus the packing list in the format your warehouse reads, will save a day at the receiving end.
The bundle that leaves with each microphone
A studio buying a voice position rarely stops at the microphone. The same order usually carries a Yinyu recording microphone for a second voice in the room, a OEM professional condenser microphone for a streamer who records away from the interface, and a OEM usb gaming microphone as a spare for a heavier body.
Audfine headphones travel with nearly every order of this kind, because the person who buys a microphone is the person who monitors the take, and the Yinyu cable range comes off the same workshop floor.
The questions a walkthrough always brings up
Can you film a specific stage for us?
Ask, and name the stage. Pointing a phone at a bench for two minutes isn’t a large request.
How many units get listened to?
Ask whether it’s every unit or a sample from the batch. The honest answer tells you what kind of line you’re dealing with.
What happens to a unit that fails the check?
Ask, because a real line has an answer and a staged one doesn’t.
Can the body be opened for a service?
Ask about the parts that wear. A product that can be repaired earns a second order.
Where the parts come in
The line starts at a receiving bench rather than at the first assembly station, and that bench decides a surprising amount of what follows. Mesh, capsules, tubes and switch bodies all arrive in trays, and a tray that gets checked on arrival is a tray that never puts a bad part into a good unit.
Ask what gets counted and what gets measured at that point. Counting is cheap and measuring is slow, so a factory that measures is telling you where it thinks the risk sits. Ask what happens to a tray that fails the check as well, because a factory with no failed trays has nothing to show you.
What the packing bench decides
A microphone is a shape in a box for several thousand miles, and the packing bench is where that journey is won or lost. Ask what sits between the microphone and the carton wall, and ask whether the accessories are boxed separately or thrown in beside the body.
Ask how the grille is protected specifically, because a dented grille is the damage that turns a good unit into one that can never be sold at full margin. A foam collar costs very little and it’s the difference between a batch that arrives clean and a batch that arrives with a claims conversation attached to it.
Ask what the master carton holds and what it weighs. A microphone is light and the carton around it’s what the freight is actually priced on.
The record that follows a batch
Ask what documentation leaves the factory with a shipment. A packing list in the format your warehouse reads, photos of the actual batch rather than of a sample from last season, and a note of any finish or thread deviation are all things a serious line produces as a matter of routine.
Ask how far back the records go as well. A factory that can trace a serial number back to a bench and a date is a factory that can answer a complaint instead of arguing about it, and that ability is worth more than any single figure on a datasheet.
Book a look at the line
Tell us which stage you want to see and which microphone your customers use, and we’ll film the first and quote the second. If you’d rather see the whole line in one pass, ask for the workshop clips rather than the exhibition ones, because the workshop clips were shot on an ordinary working day.
Condenser microphones in this range are made by Ningbo Lesound Electronics in Zhejiang, where the capsule bench, the listening station and the packing bench sit within a few metres of one another.
