Full marks to The Equinox for its solid, chunky plugs. They give a super-snug fit without the more complicated mechanism of the Crystal Cu's WBT plugs.
The Equinox offers resolution befitting the price, but is let down by the lean, weak sound that it promotes. Bass notes need to be meatier and more substantial. The lack of bass means music sounds top heavy, with the treble dominating. It sounds like higher frequencies are leering over you.
