Sound quality is great... iPad app?

The sound quality is GREAT! Wish they would update the headphone database. They are many new headphones out there which are not in the list. Also, would love for an iPad app. I cant seem to adjust the treble manually with the iPhone app on the iPad. Would gladly give it 5 stars if those were available.
