Overall, V-Moda does an excellent job with this headset adapting the finest qualities of their high-quality Vibe earphones into this twin Vibe Duo headset. They have also integrated a very capable microphone with passive noise cancelation for telephony use. Anyone with an Apple iPhone who is trying to enjoy the best sound possible would really do themselves a favor by grabbing up a set of these high-quality and extremely comfortable headphones. We can only hope to see more “all-in-one” mobile devices like the iPhone so that more users can take advantage of these great dual-purpose headphones...
