Thank you all for your replies. I'm still researching like crazy. But I'm not sure how to tell from the specs of the portable amp/dac which one has the most driving power. Because I've found so many but can't tell which is the most powerful. Like for example the Topping NX5. Looks powerful...

I guess there would be no way to know the difference between powering them according to the "formula" and giving them as much power as they need. So the ifi hip you think would be enough?Do you know if there's a doable way of converting t50rp mk3's to balanced?

Thanks that's really helpful. Do the Fiio BTR5 and ES-100 have more or less power than the q1? Also, to use the balanced port, do you just need to buy a balanced cable and swap it out, or is there something you need to do to the headphone itself? Thanks!

Thanks so much for the reply! So you don't think the q1 mk2 would cut it? How can I tell how much power I need from the amp to meet the specifications of the headphones? I know there's that calculator but I don't really understand how to use it.

Not necessarily with bluetooth. Just something that I can take around and not have to worry about pluggin in. Thanks for your reply!
