I bought the DUNU titan 3 that are more mid centric and has less bass then titan 5 and I don't regret with his purchase, I heard the titan 5 and didn't like the amount of bass it has its more suitable for bassheads.
DUNU Titan 3 sound great for their price (89$ winter aliexpress sale).
I have the HD58x jubilee and the titan 3 are on par with them, soundstage thought much smaller on the titan 3.
Its important to give them at least 20-30 hour of burn in cause right out of the box they sound dull.
