Bests & Worsts Reviews from Amazon

I must be the most unlucky person with these. I've payed for 4 pairs, only 2 have arrived. I don't know what amazon's problem is but they've lost two during prep for shipping, so they were "undeliverable." I had to call in to get my refund, 9 days later, even though they showed the record of undeliverable. Ridiculous. Shipping isn't the fault of the manufacturer, but quality is. I've had a black pair (bought retail at best buy, because amazon couldn't get me a pair, even when I paid) had terrible feedback and interference issues. Randomly during jogging, it would get garbled and have extremely poor distortion that was physically painful. So I returned those to Best Buy. Then the red version became available on amazon. Sure, why not, try once more. If this doesn't work out, I'll just move on to something else. Oh boy. So they were great. For 3 days. Then they lost their volume. Maybe it was a setting in my phone? I saw that was a thing online. Nope, and tried it on 5 other devices from tablets, to my computer, TV, direct connect to an echo device, etc. It was bad on all of them. Basically it wore itself out in 3 days. Had the tinny sound of a dying driver. Not exactly a good sign. So I have to give this the worst rating, as it is extremely poor in quality control. Nobody is making sure these are well made before shipping. I might be the 1 or 2 percent that slips through, but it happened more than once. I cannot say with any confidence that anyone should buy these terrible earbuds. Massive thumbs down. Until then, I'll go back to my big Sony Hear On 2's. I wanted something compact vs over-the-ear, but obviously Samsung has struck out.
