I have the mh1 and the Monster Gratitudes are a significant upgrade in every aspect: detail, imaging, etc......and I think you will love the bass (one of the best attributes). A $300 phone that has been discontinued and now can be found for $60. A ridiculous value at that price point!
I see it differently. I see it that marketing has convinced you the Gratitude is worth $300, when it really is just a very good $60 earphone.
