Portable DAC/AMP suggestion for 250 Ohms headphones

[shafirpl]

Greetings,

I am looking for a portable DAC/amp recommendation for driving my Beyerdynamic 250 ohms headphones. At home, I use a Soundblaster Omni surround with my MacBook pro. But I am looking for something that is portable, that I can use with iPhone XS max as well as my work laptop (MacBook air) at the workplace or when I am walking around, so it should be portable and easier to put into pocket/carry.

My budget is around 100-150 USD and I reside in Vancouver, Canada. So amazon.ca or eBay I think will be my source for purchase.

Do you guys have any recommendation? Thanks

First link is the dac/amp, second is so you can use it on your phone.

Not sure but I believe a fiio k1 should work
