DAC/AMP for 24 ohm headphones

[Kasenumi]

Hello everyone

I got SONY MDR XB550 headphones as a gift to use with my smartphone/tablet and outside the house. The sound of these 24 ohm headphones is nice but comparing to Beyerdynamic DT990 600 ohm paired with external DAC and AMP it is hard to enjoy the music. I need something (might be DAC and AMP combo, 2 in one) to make as much magic of 50$ headphones as possible.  

The question is rather what should I buy to make that magic than if I need to buy anything at all, because I need it. I am sure there is something that exists for such cases. 

Thank you for your answers and advices.

for lower impedance headphones you wont get much of a difference with an amp. 25 ohm  is rather easy to driv eand you can drive it off a phone or motherboard no priblem but if you just want a portable DAC/amp the meizu hd pro is pretty decent and sounds better than most dongles
