Received my Velodyne VTrue tonight!
First impressions out of the box (my first impressions usually don't change much after extensive evaluation)
Portability: They are heavy and bulky, plus they do not fold. My M-100 feels feather light after wearing the VTrue. Their weight feels comparable to Beats Pro. Build quality is top shelf- solid aluminum and plush leather. Since they were fresh off the UPS truck, the thick metal was very cold. I had to search for plastic on this headphone and it is only around the dual cable inputs. Cables are high quality cloth and seem relatively tangle-free. Despite size and weight, they are reasonably comfortable. They are very cool looking in person and feel luxurious. VTrue is driven reasonably well from my Iphone and responds well to amping.
Sound: These are clearly basshead cans. Bass rivals my M-100 in terms of quantity and quality, maybe even a little more punch with VTrue without being boomy. Mids are detailed and are also comparable to M-100 and UE6000. Mids also seem more forward. Highs are noticeably rolled off compared to the M-100 and even slightly compared to the UE6000, but not as dark as something like the Aiaiai TMA-1 or some of the Pioneer DJ headphones. I would say these are excellent sounding headphones, but I need more time with them to determine if they are for me. I consider my M-100s to be my go-to, multi-genre audiophile headphone even though they have been categorized as basshead cans. I am actually looking for a secondary quality basshead can and will see if these meet my needs over the next few weeks. If you are looking for a basshead can with deep, tight bass, good midrange detail and don't mind rolled off highs, you may want to check them out. If I had to compare them to another headphone sonically, I would say they are a classy, improved ATH-PRO700MK2. These have a luxurious feel that you don't experience with synthetic materials and Velodyne didn't skimp on the build quality.
