I was hoping for some help in choosing some headphones for a gift. Budget is $100-200 and as it says in the title the user has an Essence STX and listens mainly to Rock with some gaming and TV streaming too.
Any suggestions appreciated.

The Mad Dogs do not need amplification beyond basic needs. They can be powered by an iphone/ipad. They can scale with better equipment. But let's not make it sound like they are not efficient, when they're highly efficient.
Also, the STX which the OP stated is the source has more than sufficient current output for the MadDog, and most headphones.
