I really wasn’t expecting this. While I liked KEF’s original M500 headphone when it arrived in 2013, I can’t say I was ever smitten by the sound. But the new M400 was quite the opposite: I loved it from the get-go and immediately connected with it. The newer model is a smidgen less expensive, and it features a cleaner design and deftly executed, mostly aluminum construction, deliciously ample ear pads, and a rich tonal balance.

THE VERDICT
The NAD Viso HP30 on-ear headphone’s plush midrange and punchy bass supply a visceral kick beyond the reach of most on-ears.

NAD rocked the audiophile world in the late 1970s when it introduced its astonishing 3020 integrated amp. That amp eventually became one of the best-selling of all time and established NAD as the brand that prioritized performance over superfluous features and glitzy styling, at affordable prices. That “sound quality first” ethos continued over the decades, and NAD recently scored another direct hit with its Viso HP50 over-the-ear headphones. So, I was eager to check out their new Viso HP30 on-ear model.

THE VERDICT
The EnigmAcoustics Dharma D1000 seamlessly melds dynamic and electrostatic drivers to produce ultra high-resolution sound.

Even though I was hearing good reports from friends about the EnigmAcoustics Dharma D1000 hybrid electrostatic/dynamic headphone, I was still more than a bit skeptical about how successful the blending of its two drivers could be. AKG made hybrid dynamic/electrostatic headphones in the late 1970s. I auditioned a pair just a few years ago and heard the electrostatic tweeter and dynamic driver as two separate sound sources. Thankfully, the Dharma D1000 aced the blend—the two drivers sound like one.

THE VERDICT
The PSB Speakers M4U 4 blocks a good amount of external noise, feels comfy, and sounds sweet. What’s not to like?

PSB Speakers’ Paul Barton is a quick learner. After decades designing his company’s speakers, he jumped into headphones with the PSB M4U 2 full-size, noise-canceling ’phones. The M4U 2 was hailed by critics and consumers alike, and his next design for NAD, the Viso HP50, was even better, Barton was clearly on a roll. Now, with the M4U 4, Barton may be the first celebrated speaker designer to ever tackle crafting an in-ear headphone.
