I am a big fan of on-ear headphones, which attitude bucks the noise-cancellation trend. The design is a nice compromise between over-ear and open-back styles—the latter of which can present the best soundstage. Cans that rest on the ears, rather than cover them, tend to be lighter and confer airier, more natural sound. However, they also leak noise both ways, which makes them less appealing for commuter trains or air travel.
Since I reviewed MW60 Wireless last week, I simply must point out that Master & Dynamic launched MW50 on-ear Bluetooth headphones today. Yes, I plan to review them in the near future. The company says the Fifty is one-third lighter than the Sixty, while adhering to the same, retro-design ethic and modern materials—aluminum, lambskin, leather, and stainless steel.
