I'm sure you won't regret it.

I've had M80s now for about 2-3 months and every day when i listen to music i can't help but think "what definition! what incredible detail!
what is most wonderful is the definition in the high frequencies;
the cymbals and brushes on cymbals are super good, all detailed and smooth at the same time.
same for the mids, very detailed, smooth and linear.
can't say anything about the lows, as i use a sub all the time.
