So, someone asked for a comparision between the Gratitudes, Havi B3 and the Piston 2.0.
I dont have a lot of time now so it'll hav to be the short short version:
The Gratitudes and The Piston has a similar general sound signature with a nice deep bass and very nice air to their sound. They also have a very nice attack and the sound is lively and in you face. There should be no surprise to anyone here that I really love the Gratitudes and regard them very highly. I think they're a gret fun to listnend to. As allready mentioned the Pistons offer much of the same. The biggest difference between the two would be that the Pistons has more bass quantity. It's not the ususal midbass hump but more of the subbass that makes the Gratitudes so great. The Piston also seem to be slightly airier overall compared to the Gratitudes. Vocals are also a bit more forward on the Pistons. The Gratitudes were said to bring a "live sound" when they were released and the Pistons does this even more. The bass of the Piston may be a little to much on some tracks but other than that they are truly great. I would have a really hard time picking a winner between these two.
The Havi B3's on the other hand are pretty much the opposit (if that's possible in sound) of the Piston's. They are much more well balanced. The bass doesn't reach as low but it never ever get near boomy or too much either. Still they doesn't feel bass light and belive me, I love my bass. Music is presented in a very relaxed way. The airiness of the Piston's is gone but instead there's a very nice weight to every tone. String instruments and voices are just amazing. Someone else metioned earleier that Infected Mushrooms sounded great with the B3's and that is very true. There's something in the way they present music that makes it feel very unforced if that makes sense?
One thing worth metioning about the B3's is that there apparently is/were several versions of them. I bought mine from a listing stating they were the "Professional" tuned ones and also got that confirmed from the seller when asking. However, since there's no visual signs to tell the diiferent versions from each other I cannot be 100% sure.
I've been listeing to all three from my Magni with the Fiio X3 line out as source and from my computer through the Udac2. I'm using Sony hybrid tips on the Piston's and Syny foam hybrid tips on the B3's. I've also struggled a bit with the fit on the B3's and finally ended up adding some earglides so I'm happy now.
