Frequently Asked Questions
The 400S are more budget-friendly, but the 300 Pro generally offers a more refined soundstage and slightly better build quality.
They will, but you might find them a little quiet; a portable amp can really open them up.
While decent for casual monitoring, the limited frequency response and closed-back design aren't ideal for critical mixing work.
