Cons
Con Limited inline controls
The inline remote only allows you to play, pause, and skip tracks. You can’t control volume levels though.
Con Mids may be too in-your-face
The boosted mids may make the music sound unnatural if this is a sound signature that you are not used to. Vocals may be too loud, and guitars, especially with distortion effects, can be abrasive.
Con Non-standard remote function activation
Activating the functions with the remote takes some getting used to as it's different from other remotes. For example, you need to hold down the volume button for 2 seconds instead of the usual double tap to skip to the next song. This can get annoying if you're used to the standard way.
