I'd never listened to any iem's from Custom Art but had read good things about them on Head-fi so I decided to give these a try.
As it turns out it was a great decision, these are beautiful iem's with extended bass and superb treble the mids aren't bad either.
These are proving to be perfect for listening on the move and while working. They are detailed, have a great soundstage and are beautifully musical.
Very nice IEM for the price. Nicely balanced sound with great bass
