Does the DT 240 Pro need a headphone amp?

No. At 34 ohms and 119 dB sensitivity it plays loudly from a phone, laptop or camera output. An amp only helps if you want more headroom or a lower noise floor.

Is it good for recording vocals?

Yes. The closed-back cups keep sound from leaking into the microphone, and the light weight helps during long takes. The coiled cable is short, so you may need an extension.

How does it compare with the DT 770 Pro?

The DT 240 Pro is lighter, folds flat and is easier to drive from portable gear. The DT 770 Pro has larger velour pads, a wider soundstage and comes in higher impedances for studio amps.

Can the cable and pads be replaced?

The cable detaches, so a replacement is straightforward. Pads are user-replaceable, though the pleather ones wear faster than velour.

Does it fold for travel?

Yes. The cups fold flat on hinges, which makes it easier to pack, but no case is included.

Is it noise cancelling?

No. It is passive closed-back isolation only, which cuts some surrounding noise but not engine drone like active models.
