TechPowerUp posted a review on the XENNS UP In-Ear Monitors
A quote from the article:
Mangird is now XENNS, and builds upon its impressive Tea IEMs with the newer XENNS UP. It is a tribrid set employing seven drivers for a promised extended frequency response coupled with audiophile tuning and technicalities, as well as individually hand-painted face plates that make for a unique set each time.XENNS UP In-Ear Monitors Review
