The EVR and VE5 were both designed for vocalists specifically, but I have never heard the VE5. I will say that I personally enjoyed the EVR very much, it was one of my favs in the earlier phase. It combines a clear sound with a delightful touch of sparkle, and was to me somewhat reminiscent to iems as the NT6pro and Gemini. It's an iem I enjoyed listening to classic rock or acoustic music with, as a slight lift in its upper treble lets string instruments sparkle and shine. Its bass is fairly linear and will not necessarily be a showstopper, but it's there doing its thing. Despite it being targeted at vocalists, the vocal body is not as large or forward as something like the Phantom or Zeus; both the instruments and vocals are fairly neutral in terms of body and forwardness. Overall, one could say the EVR is a playful deviation of neutral.
The ESR is designed to be very flat, where neither the bass, mids, or treble standout from one or another. The mid-bass is tight and resolved, but not overly present or impactful, the midrange has a nice tone, but is not overly bodied or forward, and the treble is fairly linear, without being overly sparkly nor laidback. It offers a clean, well-separated sound with precise imaging. In a way, it is kind of a prototpye of what an iem should do right, without necessarily failing or excelling in any area for that matter. This is more of a classic 'neutral' iem, taking over the role of Spartan.
Normally weekends are reserved for a very strict Netflix binge-watching schedule with the gf, but she has to grade some papers tomorrow so maybe I will try to race Daniel for some impressions on the other hybrids
I just finished editing a large majority of the photos, commenced on the introduction aaaaaand I have to wake up at 5.30 AM for church/work tomorrow. But, never fear; free time is an old friend, and I tend to work just that little bit harder in the face of competition.
