Terrible product- is also not returnable and do not waste your money. - AXIL XCOR Pro Hearing Protection Ear Buds

AXIL Xcor Hearing Protection Ear Buds are difficult to properly fit/position in ears, did not block loud sounds adequately using the recommended foam inserts, in noise reduction setting earbuds hummed/had crackle sound which was annoying, volume buttons are difficult to set, earbud speaker quality is extremely poor frequency range and completely unnatural sounding, bluetooth function does not have an off button (must turn off bluetooth from paired device and light will blink 5 minutes if not paired). Recommend getting another brand of earbuds, over the ears headset or just use cheap high quality foam ear plugs instead.
