The NAD VISO HP70 headphone is the fraternal twin to the PSB M4U 8. Both have essentially the same internal components and specs, and both are equipped with the latest iteration of Paul Barton’s RoomFeel tuning. That is where the similarities end however, as their external design and aesthetics are about as different as can be.
With their modern design and crisp, clean sound, the NAD Viso HP50 headphones and PSB M4 U4 IEMs aim to be the go-to choices for today’s audiophile road warriors.
The NAD HP50 is the latest headphone design from Paul Barton, founder of PSB, a sister company of NAD, and features a new trademarked concept called RoomFeel. RoomFeel attempts to recreate the sound of listening to high-end speakers in a room. Most listening rooms add a low frequency bump to the sound that is often not taken into account when designing headphones. A room gain compensation transfer function was developed to add a +3 dB per octave boost from 200Hz down to 50Hz in order to replicate the fuller, warmer sound of a room. Clearly a lot of time and engineering has gone into the development of these headphones, the only question is, did it pay off? Yes it most certainly did.
