Yamaha HPH-150B

They feel a bit plasticky, but are otherwise light and comfortable. Unfortunately the sound quality is very poor in combination with my high-end Yamaha digital piano, especially when the piano's 'binaural sampling' is enabled... the sound is dull, with heavy mid-tones, and quite different to the piano's sound without the headphones. (By comparison: when I use Sennheiser Momentum 4 headphones in combination with the digital piano, the sound is clear and almost indistinguishable from the sound without headphones.)
