VK-X ANC MICROPHONES

PRIMO Noise Canceling Microphones received in Paris

 

Good afternoon everyone!

 

Lucas here. I hope my blog post finds you well. Last week, we received the microphones for the VK-X Noise Canceling system. I am happy to share some pictures of them and to present how we placed them. If you have any question, please post them below!

 

 

2,300 PRIMO Microphones

 

 

The Noise Canceling microphones are part of the components for which the sourcing was impacted due to this year’s electronic shortage. Luckily, Baptiste managed to find an identical reference from Japan-based and famous PRIMO brand and secured a 2,300 units stock that we received last week at the workshop. Each pair of VK-X headphones will house 2 PRIMO microphones for its Active Noise Canceling system. Those microphones are pretty small: 2mm wide and 6 mm round, – they did not clutter up the workshop yet, but we’re still counting 😉

 

 

 

 

How are they placed inside the VK-X?

 

 

Feed-Forward Noise Canceling microphones need to be perfectly isolated from the inside of the headphones to record properly the surrounding sound, which will be electronically canceled when playing your music. As you can see in the mechanical renders that Alexandre created for this post, we placed them on each earcup, behind the little 4 points grid located on the back side of the VK-X (the renders are showing the left side of the VK-X), which appeared to be an ideal compromise between design and recording position.

 

The ANC microphones are isolated from the inside of the headphone thanks to a custom Silicone Joint, itself held in the Internal Plastic Shell that fits inside the External Aluminum Cup.

 

 

 

How are they connected to the main Electronic Board?

 

 

Each ANC microphone is being soldered by hand at the workshop to its connexion cables as you can see on the close-up picture below. On the left side of the VK-X, the microphone is connected directly to the main “doughnut” electronic board. On the right side, the microphone is connected first to a small slave electronic board, that is then connected to the main electronic board through the headband.

Hey, Awesome, looking forward to it. One thought: have you planned on implementing various levels of ANC? That would be a nice touch, especially considering ANC does sometimes influence sound. Though of course, I trust with the unique little marvel that is your sound signature, you will have been nitpicky enough to have anticipated that. Also, seeing their design I assume the headphones will have pretty good passive NC to begin with, so have you thought of a “transparent” mode where outside noise is let in? I am sure I would get a great deal of mileage out of that… Read more »
