Are the MC-150 good for recording vocals?

Yes. The closed-back cups reduce bleed into the mic, and the detachable cable means a snagged cord won't yank the headphones off. They are a common pick for tracking sessions.

Do they fold up for travel?

They collapse into a folding design and come with a soft carrying bag. That makes them easier to pack than fixed-cup studio headphones.

Can I replace the cable?

Yes. The 9.8 ft single-sided cable is detachable and locks into one earcup with a 3.5mm stereo mini-jack. A replacement cable can be fitted if the original wears out.

How do they compare with the ATH-M50x?

The MC-150 has larger 50mm drivers and a longer 9.8 ft cable, and it folds with a bag included. The ATH-M50x has a longer studio track record and a more compact fold, so the choice comes down to cable length and brand familiarity.

Do they need an amplifier?

No. The 3.5mm jack works with phones, laptops and interfaces, and the included adapter covers larger headphone outputs. A dedicated amp helps mainly on quiet sources.
