Does anyone know anything about these boasting 1000 resistors needs 5vdc and has internal relays ?
① The overall seal design, the use of aviation-grade aluminum alloy materials using precision CNC manufacturing aluminum forming. Shell with frosted gold process technology. long lasting.
② Using potentiometer control MCU high and low level, pure resistance circuit, exponential curve, adjust the sense of smooth.
③ With the Netherlands VISHAY one thousand high-precision chip resistors, with high reliability, anti-vibration ability. Solder joint defect rate and low. High frequency characteristics of superior. Reduced electromagnetic and RF interference to sound quality is a good guarantee.
④ Omron audio gold contact signal relay, with long life, gold-plated contacts mainly to improve the contact contact resistance, loss of long life, to ensure good contact.

This could be a stepping volume controller, using a signal relay to initiate a mute function.
Or it could be a relay selected stepping vol pot, but very unlikely in such a small case.
Or it could be codswallop since there is no specification against which to compare the product to what is (not) promised.

Sounds like an excellent way of emptying your wallet. Sales bullsh1t or what!
Looks like a standard cermet pot in the opening. If pure resistance as quoted, it would be passive, not active.

this does seem to suggest power is required, no?(6 to 9v but is that DC or AC?)would be interesting to see the insides.

and it states there is a relay.ebay link "Note: This potentiometer system requires a set of DC5V voltage"
That's why I thought here might be a mute

Well, the title says it all. It's a potentiometer with six feet. 😀
No, seriously, the description seems to imply somehow that it might be an R2R stepped attenuator. Maybe it's controlled via the small pot visible in the photos. But I wonder how that would fit into such small case. I guess there is only one way to find out...

+1 looks like one of these.

The "thousand" perhaps was meant to be thousandth in resistor precision.
The pot in the front could be a DC divider that tells the MCU about its angular position, so as for the latter to determine a relay combination for the stepping resistor network.
It appears to be a challenge for the given space, but with a flexible PCB it's probably doable.
