eBay is running 10% / 12% off (eBay Plus) promotion at the moment so after 10% off, this headphone is only $29.69, it's still around $45 (on sale) in their official store plus shipping cost (RRP $108), https://www.xmpow.com/en-au/products/mpow-h12-ipo-active-noi…. Their official store has 12 months warranty.
Android Central rated this headphone "shockingly good" for something under $50 (https://www.androidcentral.com/mpow-h12-noise-canceling-head…)
Please note that the model "H12" uses micro USB charging but "H12 IPO" is the upgrade version which uses USB C fast charging.
I have eBayplus and this seller doesn't seem to offer free delivery.
