Sennheiser CX 890i in-ears for $51 w/free S&H

Deal-fishing at Tanga also finds the new condition, in retail packaging, Sennheiser CX 890i in-ears for $51 with free shipping, with a limit of eight. They are available in black only. The white color scheme sold out. The details page says “30 day warranty” instead of the usual two year Sennheiser warranty. Not sure if it’s a typo or not.
