I have the MDR7506 and would never take them riding, too big and the cord is the curled type which gets tangled and is big.
The sony pro line is nice but they don't have the smaller MDR's anymore which is a shame cos they were great.
I like the smaller consumer sony's too. Have had pairs last for years. These look cool, don't know much about them tho > MDR-PQ2 | Giiq Headphones | Sony Canada
They are the MDR line though so could be good...
