Based on the available info from CES 2013, The NAD Viso HP50 is the new headphone introduction that I am most anticipating from the brief product description link below. While the flood of new headphone introductions from respected names in audio has been hit or miss over the past year, Paul Barton, the man behind PSB and the PSB M4U1/2, is also overseeing the launch of the NAD Viso HP50 which is being described as a PSB M4U1 with more bass! While the preference for more bass is subjective, I came away from my listening experience with the M4U2 thinking they were close to perfect if only there was a bit more bass presence (in passive mode which = M4U1). If they live up to this description, IMO, the HP50 will be hard to beat at $279.
From the picture, the headband looks smaller, more durable and flexible to address the headband cracking issues of the PSBs that seemed to be their Achille's heel, although it does not appear to fold like the M4Us (yes, I recognize this is an assumptive leap from a prerelease photo).
Anyone who has read any of my posts knows I am a huge M-100 fan due in part to the quality and presence of their bass in relation to the mids and highs. However, if the M-100 never existed, I would be a proud PSB headphone owner and I anxiously await the day I can A/B the M-100 with the HP50. I do prefer the classic, more mature look of the HP50 since I have the self-awareness to know I am much too old to look "right" wearing M-100s.
