Beware of factory USB-C cable !!
I bought the famous UMIK-2, an excellent product recently. Bought a laptop for measurements too (Dell Latitude) so I thought I can finally start my serious DIY loudspeaker building journey.

Well, this UMIK-2 gave me connection errors in REW: sometimes the mic was ready, sometimes it just disappeared from the system completely (not only in REW).

I checked USB power options, didn't help. Checked with another laptop, didn't help. Checked with a desktop PC, didn't help.

Then I tried a different USB-C cable, borrowed from my Raspberry Pi4, a thick, quality USB-C cable from Varta. And voilá, it works like a charm.

The factory supplied USB-C cable is still good for my phone interestingly, charging works, data works. But the UMIK-2's USB-C input connector and the factory supplied USB-C cable don't like eachother... - a unique feature of the cable (or the UMIK-2).

So I STRONGLY recommend anyone who buys a UMIK-2 to separately buy a very good quality USB-C cable for the mic else he can have issues with the factory supplied cable's connector (I assume the cable's connector is cheap and not so good, not the UMIK UBS-C input).

Anyway, having tested the UMIK-2 with a quality cable, no connection and plug-unplug issues anymore, the mic is working like a charm and it's a real joy to finally use it as intended.

A note to MiniDSP: check your supplied usb-c cable's connectors, next time I'm willing to pay $1 more (lol) for a stable, working cable.

I was afraid I would need to RMA this mic to Audiophonics in the upcoming days but it seems the cable's connector doesn't fit very well into the UMIK's USB connector but since the UMIK is working fine with a better, more robust cable, I assume this is a cable issue and the UMIK is fine. :)

Works as expected for loudspeaker measurements with REW. It was packaged well and is of good quality for the price. Cable has USB-C connector for the microphone but USB-A at the other side, so I needed to use an adaptor to plug it into my Macbook.

Fonctionne très bien
Le microphone fonctionne très bien avec le logiciel REW et le fichier de calibration téléchargeable, ça donne des mesures très précises même dans les graves et à moins cher que les bidules de Big Sonomètre qui coûtent plus de 1000 voir 2000€ où en plus il faut payer encore des centaines d'€ pour avoir l'analyse avec des octaves plus précises, ici c'est moins de 300€ et toute la précision qu'on puisse vouloir raisonnablement et +
Il faut faire attention cependant car il est recommendable de l'utiliser sur un pc portable alimenté par batterie, sur un fixe on manque de portabilité et il peux y avoir des interférences

Perfect
Très bien...utilisation professionnelle...

Excellent product, easy setup, accurate results
Perfect service by Audiphonics, excellent measurment microphone, easily set up for working with Room EQ Wizard on Windows via ASIO driver. No problem in obtaining the individual calibration files from MiniDSP. All in all, five stars.
