My budget for headphones is around €150. I don't mind if the headphones don't have good Active Noise Cancellation (ANC) or Noise Cancelling (NC) features. I just need the sound quality to be decent or good, and the headphones should not leak sound.

I will mainly use the headphones for listening to various types of music, but the vocals of a track are the most important to me.

I intend to wear the headphones while working at the office or running, so I would prefer headphones that have a sturdy build quality.

A huge bonus would be if I could effortlessly and problemless connect two devices to the headphones. i.e. my phone and laptop at the same time. Would be willing to up the budget to 200 for this.
