VS Unique Melody MEST mk2:
Yes, these two IEMs are in totally different sides of the spectrum, driver configuration wise but are priced closer. MEST mk2 sells for $1599 while the VE6XC asks for 1650 Euros.
The single DD of the mk2 has better volume but does not have the sub-bass reach. In comparison it lacks a bit with weight. Decay speed is faster. Mid bass is more dominant where the XC has sub-bass tilt. Mid range is slightly recessed with the MK2 as the bass and treble have more energy and unlike the XC I can feel the crossover points at both ends. XC has better body and a bit less energy with the notes while the mk2 delivers more attack. Vocals of the XC are in a totally different level. The organic and emotional feeling of the XC is superior. MK2 delivers better transparency with micro details. Treble is where the MK2 gets aggressive, it has more energy and sparkle.
Imaging is another area where these IEMs differ a lot. Notes on the MK2 are less tall with wider base and sharper tip emulating a more detailed sound. Where the XC has a defined area for instruments and they either go vertically or horizontally, mk2 has most of the instruments placed at the edges of the stage and they project inward.
VS Vision Ears VE7:
VE6XC in short is an IEM much easier to fall in love with. It sounds clean and detailed with the X2 while the X1 has bass and full bodied notes. It is a level headed IEM without any temper or tantrum while delivering one of the most organic and cohesive sounding nnotes. It has a few short comings too.
It is not a budget IEM, spending 1650 Euros should mean you must know what the weak points of the IEM are. VE6XC lacks some attack, if you are used to chi-fi tuning this is going to sound a bit less attacking and not a lot engaging either. Do you miss out on any details, not at all, but the slight lack to extra energy at the finishing area of the note gives is a more level headed feel. If you want shimmery notes with more ring and cotrast, there are a lot many IEMs one can consider and the similarly priced VE7.
But if it’s the tranquility and calmness you are after, obviously without sacrificing any details (yes, it is not sharp or on the face), VE6XC is the only IEM I will recommend.
