Red I want to plug these into a music player and hit play. I’m curious how that slim headband feels in use, too.
Nea Those orange cushions make me want to revisit some older albums. I wonder which record I’d reach for first.
A slim band and an on-ear fit
The adjustable stainless-steel headband holds cushions that rest on the ears rather than surrounding them. The earcups use an open-back design. Open-back headphones generally allow sound to escape, so nearby people may hear what you’re playing.
A headphone socket, not a Bluetooth connection
KPH40 Retro connects through a 3.5mm stereo mini plug. If your phone lacks a 3.5mm headphone socket, you’ll need a suitable audio adapter.
Japan sales are through TEAC Store
The Japanese price is ¥6,820 including tax, with sales exclusively through TEAC’s official online store in Japan.
