I recently bought a pair of Atrio M5 MG7 earphones. I bought them because of the rave of all the bass.
I listen to them through my Macbook pro and I listen to a bunch of different types of music (hip hop, electronic, trip-hop, etc) and almost all my mp3 files are 320 or v0.
I have burned them in for close to 50 hours so far.
I can hear the sub-bass for sure and the bass when its there is EXTREMELY controlled! For songs like those by Bassnectar there is definitely a ton of bass coming through the earphones but when I listen to just about any other songs by artists like Lupe Fiasco, Little Dragon, etc there is almost no bass/midbass coming through.
I have tried all the different silicon tips and the small and medium foams they came with. I settled on the medium foam since the silicon ones were just too uncomfortable for my ears.
I have recently also bought a pair nu-force ne-700x and they seem to have A TONNNN more bass. It is definitely not as controlled but they sound like bass monsters while the MG7s leave me feeling underwhelmed and feel like bass monsters at all. They don't seem to produce any midbass.
The Ne-700x also seem more fun and there is hard hitting bass. The MG7's dont seem to have much impact.
So if I had to describe the bass difference it'd be like this:
Sub-bass = Boom Boom
Mid-bass = Boom Boom
Mid-bass = BOOM BOOM
So is this difference due to the coloring of headphones I've been listening to or do I have a out of whack pair of MG7's?
Please let me know if theres any other info you'd like to know.
