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.

The Acoustical Manufacturing Company’s Quad ESL-57 was the world’s first production full-range electrostatic speaker. It debuted in 1957 when hi-fi speakers were big boxes and used moving-coil drivers, so the ESL-57’s flat-panel, downright minimalist design not only looked like a radical advance, its thin-film diaphragm’s low-distortion and lightning-fast transient response sounded truly revelatory to 1950s audiophile ears. The speaker’s introduction came not so many years after the transition from 78-RPM records to higher-fidelity LPs took place. The market was primed for a more transparent transducer technology, and Quad had the best-sounding speaker of the age.

THE VERDICT
Audiophiles on a budget need look no further than Sennheiser’s HD 569 headphones.

My long-running fascination with Sennheiser headphones dates back to the first ones that I bought in 1972: the HD 414 with canary yellow ear pads. I can’t remember how or why they vanished from my collection decades back, so I recently bought an ancient pair of HD 414s on eBay, and the sound was even better than I remembered. I still have the company’s HD 580, which I bought in 1994—another model I keep coming back to. Listening to the company’s relatively new HD 569, I have the feeling they’ll still be cherished by their owners decades from now. They’re that good.

The Sennheiser HD414 was a game changer in 1968. In those days hi-fi headphones were all big and bulky, closed-back designs, and the compact HD414 was the industry’s first “open aire,” on-ear (supra-aural) headphone. It looked, felt and sounded like nothing else and forecast the future direction of headphone sound.
