Should I buy the O2/ O2+Odac or the little dot mk3 ?
 
I plan to use it with a sennhiser hd 600

Do you want an amplifier or a sound effect distortion machine that glows nicely in the dark ?

You need to do your due diligence and research both. During this time, one will stand out and appeal to you. Once you check the reviews, you will know if you made the right choice. Once this is done, you are ready to purchase.
 
Good luck on your journey!
