As far as an upgrade goes I'm sure it's worth the money but more importantly how much of a sidegrade is it? If I go from the M1 to a B2 how different would the sound signature be?

THEY ARE BOTH 2 DIFFERENT SOUNDS.It's not gonna be a upgrade,but trying a new sound,as M1 is Dynamic Driver and B2 is BA.

Dual BA to be exact 

 
B2 signature is analytical, though not as analytical as Ety's, the low is tight and fast, though not very much in quantity.
 
This is my favourite IEM at the moment, so much so that GR07 sounded like pants to me compared to this (a bit unfair I know, but that's IMO)

So it'll be vastly different?

Very different mate
 
B2 is very analytical (detailed and very sparkly high and mids, but low very much lack in quantity, though it is fast and tight and solid)

To me, B2s are better in almost every aspects. Better details and soundstage, stronger bass, but the very sparkly high might fatigue some ppl.

I see. If I like the sound of the M1 do you guys think the M3 or maybe the upcoming M4 might be a good upgrade? Though the Mp4nation did say the M4 is like the B2's little brother so maybe not the M4.

What would you guys recommend for mainly rock and pop. Bands and artists like Mat Kearney, Paolo Nutini, James Morrison, David Choi, Sara Bareilles, Kina Grannis. They have a stronger focus on vocals and acoustic and I love vocals. I'm mainly looking at the Brainwavz because I want to be a fanboy but honestly I'm open to any recommendation. I was thinking of getting the M3 until I saw the M4 teasers and the special on the B2s

B2 don't have stronger bass.they have almost no bass at all compared to M1.Get M3 for an upgrade.or,take a chance with M4.

From the mp4nation forums, the M4 has better bass than M1 and is looking to be great from the early bird price. Should be great for rock music

I will recommend the B2 because it's very detailed and even it has little less bass than other IEMs. I will also recommend the EX600, HF5, MTP Gold and TF10Pro for these genres music and they are good upgrade over M1.
