hey guys,
ultimate ears Ue-4vi are the way to go, I had the vmodas and i had the exact same problem, the left ear was WAY quieter than the right, I took them back and got store credit, then I purchased the UE's on Ebaay new for about $70. Im much happier with these over the vmodas. The UE's dont have as much bass, but they are much more crisp and clear than the vmodas. Also they have the mic control buton down low so its easier to use. i think the Apple store sells them for $150, but look on amazon and ebay and you can get a deal
