Do the HAS-30 headphones need an amplifier?

No. At 32 ohms and 100 dB sensitivity they run from a phone, laptop or audio interface headphone jack. An amp is optional, not required.

Can I use them for recording vocals without bleed?

Yes. The closed-back design limits sound leaking into a microphone, which is why they suit tracking and voice-over work.

Yes. The 9.5 ft straight cable detaches, and the box includes a 3.5 mm to 6.3 mm adapter for studio gear.

No. Isolation is passive, from the closed-back cups and leather pads. They reduce noise but do not cancel it electronically.

They work for both through the wired connection, but there is no boom mic. You would need a separate mic or a cable with an inline mic.

They are easier to drive and cost less than many 250-ohm studio models, but they trade some fine detail and build refinement for that convenience.
