Query: A bargain

The sony MDR 7506 is the best headphone for this price. It is very precise and not too bassy unlike monsters beats models. It's great for FLAC files and reveals a lot from such compressed music. I think it is better to use them with a DAC/AMP. On the other hand, they are foldable so good to put in a bag and travel.
