Strengths: Good balanced sound and bass. Good mic. Comfortable with supplied cushions.

Weaknesses: Cable reliability!

Summary: Right channel dead after less than 30 days of moderate use! AVOID purchasing the Vibe Duo until V-moda redesigns it. Warranty was only good for 14 days from vendor and void by V-moda since it was not purchased direct from them. Very disappointed!

Strengths: sound quality, cloth cord, snug fit

Weaknesses: clumsy button functionality

Summary: This set of headphones has been a pure joy. For me, there is no comparison between the stock ear buds and these. The sound is very clean, crisp and does not distort. I find the bass to be sufficient, but some may complain. Though, I suppose that these are a huge improvement regardless. All of that said, there is one characteristic I cannot stand. That is that the button to answer/end calls and pause/resume music is clumsy. I often find myself searching for it with my finger tips, were with the stock unit, it was no problem at all. Certainly something to keep in mind for the next model VMODA. (Sorry, down one star) In addition to all of this, I had an incredible experience with the tech support. After calling in and requesting a replacement pouch, they promptly sent the pouch and more ear adapters. They were very helpful and seemed to care about me as a customer and how I was satisfied with the product. I highly recommend these to everyone. Though the price is steep, it is well worth it. They even have a one year premier warranty. Maybe that is why they sent the pouch with no delay and I didn't have to talk to someone in another country to get it done.
