Just a bit of info which might be useful to some. I had a pair of AKG phones which I broke and looked around for some new ones. I’ve bought a pair of Yamaha HPH-150 Headphones which Yamaha say are made for using with keyboards and pianos. Just wanted to say I love them, much better than my old ones, very light to wear, the only thing to watch is the pads are quite soft so need looking after. I know that headphones, loudspeakers and the rest are a very personal choice but for me they are great.
