Simgot EP5

Then theres Simgot EP5 that's also meant to be good for wired with a debatable mic.

Add a Simgot EP5 to it.

or the Simgot ep5 (closed back).

Check out Simgot ep5 for budget choice.

Check out the Simgot ep5/FiiO JT1 as well if wanting a more budget option.

Simgot ep5 would be my recommendation.

And if that’s not quite in budget or he wants closed back I would recommend the Simgot EP5 (closed back, not studio reference, they are harman tuned)

Simgot EP5 should be available for you in that budget and will be a big improvement of the Razer kraken by a big percentage

Simgot EP5 would be my recommendation for you. Around your price range that’s what I would recommend.
