Hippo VB (Variable Bass)
Enter the Hippo VB. They have the deepest bass of the bunch, or at least appear that way because they
lack a distracting midbass hump. Their bass is also quite controlled and rich in texture, more like a
good full-sized phone, and clearly performing way above its price range. Dare I say it? … Ok, here we
go: their bass is more or less as refined as the one coming from the $1150 UE11 – but the VB put less
weight on midbass and provide more real sub-bass, so they win. At the same time they also have the
best clarity of all five phones in this review. That’s quite a feat, not a lot of IEMs can pull that
off easily. Their midrange appears linear, without peaks and valleys, and it’s “lush” and “sweet” like
the Shure SE530. Their treble can be a tiny bit harsh at times, same as the other phones reviewed here
– but it’s not overly distracting. Since the VB have open sound canals, one can stuff some foam,
cotton wool, or similar materials in it to tune the treble response to one’s liking. All in all the
Hippo VB are like beefier, more “substantial” Head-Direct RE0 with better bass, more or less equal
midrange but slightly less refined treble – and they’re perhaps a full step up from phones like the
Atrios. The best, albeit a bit far-fetched, comparison I can think of is that the VB sound like the
Ultrasone HFI-780, but with more forward sounding midrange.
