Review on Sony WF-1000XM3 Black Truly Wireless Earbuds with Mic, up to 32 Hours Battery Life, Stable Bluetooth Connection, Wearing Detection and Alexa Built-in for Noise Cancelling by Quc Bnh  (MC) ᠌

During active training, fall out of the ears. When using a treadmill, jump rope, or CrossFit, these headphones are NOT for rocking. As the earpiece's bulk is OUTSIDE the ear, any shaking will cause it to gradually pull itself out of the auricle. These headphones lose a lot of sound directly, unlike all other headphones where the bulk is in the auricle. The second sort of ear pads (included in the kit) do not even initially hold on; they immediately slip out of the ears. They lack sufficient fastening in the ear because of their less "sticky" and more matte nature. I don't know why these are required. The control is incredibly tiny and simple to activate by simply touching ANY item inside the touch area. The similar issue exists with big brothers. They are unable to tell whether you accidently touched a T-shirt or collar with your finger or otherwise touched them.
