Pro Replaceable MMCX cable
This is pretty common for even budget earbuds/IEMs these days, but it's still a feature that deserves to be called out when a lot of mainstream earbuds don't have this feature. It should be an unforgivable sin to not have a replacable cables at this point due to the ubiquity of the feature and for how common it is for the cable of a set of headphones you use with your phone to fail.
Con Vocals slightly shouty
This can be more accentuated before adjusting according to the set of tips, but it's definitely present. For an example of this, try listening to "Unknown Brother" by the Black Keys on a few sets of headphones. In that song Dan Aurbach is singing very emotionally, but isn't quite shouting. Headphones with shouty vocals will present it as him shouting. This is due to a very mild amount of distortion in the midrange frequencies.
