Bass:
BLON>UrbanFun
The beefiness and weight of the bass slam is much more satisfying than the UF's. The BLON's bass is less controlled but better hitting. The UrbanFuns have a more contolled bass but leave much to be desired. Imo the bass on the UrbanFuns cant touch the BLON's
Treble:
UrbanFun>BLON
The treble on the UrbanFuns are very forward and more present than the BLON's. Cymbal crashes have a nice sparkle to them. The BLON's with the right tips can give you a nice treble spike that can come close to the UrbanFun's, while I like the timbre of the treble more on the BLON's, the UF's take the cake because it has a better sparkle. The UF's might be a bit too bright for some people.
Fit
UF>BLON
The fit on these are much better than the BLON. Not much to be said here, I find them both comfy but the UF's don't rest on my tragus as the BLON's do.
While each set has it's pro's and con's I have yet to decide which is the best set. The UF's are a brighter, more detailed, airier, more analytical, less bassy version of the BLON's. If that's what you're looking for look no further. I think these are two very different monsters that deserve respect, but they're very different sonically so it's hard to say which is the better set, really depends on what you're looking for in an IEM.
Bassheads stick to the BLON
If you want more treble and a better fit go with the UF's
