I forgot that Yamaha is making speakers so these new pairs of headphones surprised me a bit. Anyway, Yamaha in Japan showed of these pairs of high-end headphones called the the HPH-PRO500 and PRO300. These headphones feature an iOS gadget remote and mic.
The Yamaha PRO300 features a 20Hz-20kHz reproduction bandwidth and fixed cord, a 40mm driver unit, a 53Ω impedance, and 107dB sensitivity. On the other hand, the PRO500 boasts of a 50mm diameter driver unit, 105dB sensitivity, 20Hz-20kHz reproduction bandwidth, and a 22Ω impedance.
Expect these Yamaha headphones to be released in December with prices ranging between $376 and $626.
