Shown above are the Ortofon e-Q7 (red one), EarSonics SM3 v2 and an 8gb Cowon J3. A simple, but definitely not lacking in power, portable system.
They quite share some interesting characteristics. Both have excellent midrange and treble response only differs in presentation.
The e-Q7 is the first IEM I've had and I must say that it change my view of how IEMs performs. Midrange is prominent but not as enveloping like the SM3. It's punchy and very detailed without sounding analytical (as opposed to the SM3) all nuances is presented cleanly and cohesively with a lot of musicality. Musicality and accuracy is how I describe e-Q7's mids. Treble on the other hand is as good as well. It's always sparkling and very snappy without exhibiting sibilance.
